Students have started learning about four american Tall Tale Icons.  They will be doing a characterization of each legend  and coloring a map of their travels across the United States.








John Luther "Casey" Jones (March 14, 1863 – April 30, 1900) was an American railroad engineer from Jackson, Tennessee who worked for the Illinois Central Railroad . On April 30, 1900, he alone was killed when his passenger train collided with a stopped freight train at Vaughan, Mississippi on a foggy and rainy night. Casey's actions saved many lives and made him a folk hero who became   popular in ballads sung by his friend Wallace Saunders. Due to the enduring popularity of this classic song, he has been the world's most famous railroad engineer for over a century.

Paul Bunyan is a mythological lumberjack who appears in tall tales of American folklore. He is usually portrayed as a giant as well as a lumberjack of unusual skill. The character originated in the work of American journalist James MacGillivray who wrote the first Paul Bunyan article in 1906, and an expanded version of the same article for the Detroit News. Historically, the character has been popular in the northern region of the United States, around Michigan, Wisconsin and Minnesota.  Watch the cartoon below to learn more!


                                

                                 
                                                                                                                                                                                                  
        


Johnny Appleseed was a legendary American who planted and supplied apple trees to much of the United States of America. Although throughout the years the stories of Johnny Appleseed have been exaggerated, he was a real person.

Johnny was a skilled nurseryman who grew trees and supplied apple seeds to the pioneers in the mid-western USA. Appleseed gave away and sold many trees. He owned many nurseries in Ohio, Pennsylvania, Kentucky, Illinois, and Indiana, where he grew his beloved apple trees. Although he was a very successful man, Appleseed lived a simple life. It is said that as Johnny traveled, he wore his cooking pot on his head as a hat!
Johnny Appleseed was born in Leominster, Massachusetts, on September 26, 1774. His real name was John Chapman, but he was called Johnny Appleseed because of his love for growing apple trees. 
Johnny died at the age of 70; he is buried in Fort Wayne, Indiana. He had spent 50 years growing apple trees and traveling to spread his precious trees around his country.

The truth about John Henry as the strongest man alive is obscured by time and myth.  His most famous feat was said to be when he was able to tunnel through a mountain faster than a drilling machine.  In truth there was a real John Henry that could be seen hammering railrod spikes along the Chesapeake and Ohio Railway in Talcott West Virginia.  
John Henry statue
In 1972, Michigan sculptor Charles Cooper completed this eight-foot bronze statue of John Henry. It stands in Memorial Park above the east portal of the Big Bend Tunnel near Talcott, West Virginia.

Big Bend Tunnel Most accounts have set the ballad of John Henry at the Big Bend Tunnel, near Talcott in Summers County. Originally called the Great Bend Tunnel, it was built between 1870-72 for the C & O Railroad.

Now that spring is upon us, (weather permitting) we will go out for ten minutes to allow students to earn hole punches on a card for each lap around the play field.  Once they have reached ten punches they get a healthy snack (some sort of fruit or vegetable or cheese).  Students are learning the importance of exercising their bodies as well as their brains at school.

Students are learning the TREE Writing Strategy for writing an opinion paragraph.  If you think about the parts of a tree, it will help you remember the parts of a good opinion paper.  The Trunk is like your topic sentence -- everything is connected to it.  The Roots are like your reasons -- they support your Trunk. It is important to examine the Roots. If they are strong, the trunk and whole rest of the tree will be strong.

Topic Sentence
Reasons
Examine Reasons
Ending Sentence


Students will be using to write an opinion paper about why a book should get your vote for our family book caucus night in May. 





Students are using a paragraph planning sheets to help them right a cohesive paragraph.  The example below is an example the class did together about why Fruit Gushers make a tasty snack.    This is the same form students will be using to organize their thoughts about why their book deserves someone's vote during our book caucus.
                                         nyla_tree.jpg





Click Here to get a copy of the paragraph planning sheet.



























Attention:  Keep reading 10 minutes every night (including weekends).  As soon as your student completes a recording sheet have him/her bring it in to class.  Remember the next goal is to complete four sheets (400 recorded minutes).

Students during reading rotations have decoding practice, read stories to build fluency and comprehension, and independent seatwork practice of whole group phonic skills that have been taught.  The stretch and shrink technique is being taught to students when coming across decodable words that they don't know.  The stretch and shrink method is when students slowly merge the sounds of a word together upon saying the whole word.   This year your student will be working on the following skills:

           

 Catch That Sound Phoneme Isolation 
 
 1.  Tell the student a word.  
 
2.  Have the student break the word into phonemes by bouncing the ball each time they hear a different sound.

High-frequency and non-decodable words are an essential aspect of reading fluency.  Students will be introduced to five new words each week to master.  The words come from E.W. Dolch's list that make up from 50 to 75 percent of the reading material encountered by students.   A flashcard and picture cue for each word will be made by each student.  The students will do "Sight Word Spelling" on Friday which will be sent home in your student's weekly envelope. The words are introduced in order of decreasing fluency and the weekly and cumulative lists will be posted here.

Sometimes the students will make a sight word game board to play with a partner.  Not only do the students have to read the word on the space that they land on, they also have to use the word in a sentence.
    Click Here For The Official Rules!


 
One way to have students practice automaticity with words is to make a game of it.  Students play the game Roll, Say, Keep to practice high frequency words.  Click on the Dice to view the rules and print a game board and cards.  To make it a little more competitive we have also played with each student having their own board and trying to be the first to clear their entire board by rolling the die and reading the corresponding word.  Of course sometimes students roll a number without a word on it and lose their turn.  

Click here to be able to print out the game board and cards.

We will also play games using to Dolch Words in context phrases.   

The students will learn to play "Sight Word Battleship."  The game is similar to the version that many people are familiar with, however students use sight word phrases as grid points on their boards.

Reading Comprehension:  As students become more fluent in reading, it is important to switch our emphasis from decoding to comprehension.  The students are learning to use the following checklist  when given a passage during a test taking situation.  Click on the picture at the left for a sample of a completed reading passage. 







Check the tasks as you complete them. 

_______ Read the questions first

_______ Highlight the keywords

_______ Read the questions. Cross-off the answers you are sure are wrong.

_______ Choose your answer.

_______ Put the number of the question where you found your answer.

There are no nations that begin with W or X. So They Might Be Giants made-up the nation of West Xylophone for their song. An interesting note is that
West Africa is said to be of the earliest places on Earth were the Xylophone was played.








The students have been learning about the flag of each nation in our alphabet of nations.  click on the flags to the left to do some online coloring of nation flags from around the word.

You may have noticed your student has been writing numbers in red and green.  Red Light, Green Light is an activity to slow the students down when they are forming their numbers.  We want the students to get a feel for the correct formation of each number and commit it to muscle memory. 

    





Katya circled her best of each red light, green light number. 



We are also working on matching numerals with the corresponding word by playing a memory match game.

Throughout the year all 100 of the addition facts and 100 of the subtraction facts will be introduced and practiced with the goal of mastery.   All of the math facts that will be learned this year are in Quiz Section of the website. The students can practice and check their answers. Just click on the tab labeled "Practice Quizzes" at the top left of the website.  The sequence starts at the bottom with Set A and works upwards to Set Z.  In December we completed Addition Facts Set Z and then moved on to subtraction.  We have currently completed through subtraction facts set Z and have moved on to double digit addition and subtraction with no renaming.
 
Students are using independent learning when mastering their math facts.  As a part of our morning routine, students come in and begin working on math facts using math flashcards they have made themselves to check their own work.

Students are also using cooperative learning with their math facts.  You might also notice that your student has dots that are circled next to each math problem.   Each student puts a "double check" dot next to each problem before giving their paper to a partner.  The partner then checks each problem and circles the "double check" dot if answer is correct, or circles the answer if they find a mistake.  The partner will then give the paper back and explain any errors that they may have found.  Once any errors are corrected, the partner will sign their name to the back of paper indicated that the work has their seal of approval.  The students are learning that we all make mistakes and it a good idea to get someone else's to check your work.  At the same time students are finding out that looking over someone else's work is an important job that needs to be taken seriously.

                                             Balance and Motion Unit


october_032.jpg
Our unit on balance and motion moved forward with the construction of mobiles made with index cards, rubber bands, straws, and paper clips.  It took a lot of patience and a delicate for the students to make their mobiles balance just right.  They are currently hanging up in the classroom on display.

 What's Oscar's trick for balancing his pencil on a craft stick?                                    Simple:  He attaches a wire to the pencil and clips on two counterweights.
 


Balancing objects is not as tricky as it may appear.  There is science behind what makes objects stable.   Some key  concepts that the students learned are: 

·      Something is balanced when it stays in a position on its own without being held there. 

·      You can tell something is in a stable position if the counterweights are below the balance point.  

·      The trick to balancing anything is to add counterweights below the balance point.

And this year we explore the principles of balance and motion by examining the science behind what makes a good roller coaster work.  Some of the facts that the class found out are:


1.   
To make a coaster travel all the way around the track it must start high and end low.


2.   
 The hills or loops the coaster encounters must be in order from highest to lowest to give it enough force to travel up and over each hill or around the loop without being pulled.

Some of the things we will find out about spinning and rolling objects are:

         ·      You need force to start a top spinning.

                                                                                                      Nyla                                                  

·      Fast-Spinning tops are more stable than slow ones.  You can use a guide (paper clip) to steady your spinning top.

 

·      “Bigger” tops are more stable and spin longer.  Bigger can mean using large disks instead of small disks, or using lots of small disks.

                                                     P.J. and Cody
 

·      Both tops and zoomers spin.

 

·      Tops are put in motion by pushing the straw around.  Zoomers are put in motion by pulling on the string.  Both need a force to start.

Life cycle of a cricket Crickets are jumping insects. Males of most cricket species make a loud chirping sound by rubbing their forewings together; they do this to attract females. Crickets chirp faster when the temperature is warmer. Crickets live under rocks and logs in fields, grasslands, and meadows. Many crickets are nocturnal (most active at night). The most common cricket in the US is the field cricket; the most common one in Europe is the house cricket (which is stockier).  Crickets undergo incomplete metamorphosis. They hatch from eggs that the female deposits in soil (or plant material) using her ovipositor. Immature crickets (called nymphs) look like small adults, but the wings and ovipositor (of the female) are not fully developed. They molt many times as they develop into adults.

april_030.jpgIn science we have also received our painted lady butterfly larvae.  The students are learning about the life cycle of a butterfly which is illustrated below.
                                  

may_001.jpg may_014.jpg





Painted Lady Butterfly Life CycleEgg: The Painted Lady begins its life cycle as an egg that is the size of a pin head. Eggs are pale green with 12 to 14 longitudinal ridges; they are laid on thistle, mallow, or hollyhock leaves. The incubation period is 3 to 5 days.

Caterpillar (larva)
: The caterpillar eats continually for 5 to 10 days before it pupates. The yellow-green striped, purple to black caterpillar has long spines on each segment. The caterpillar is up to 1.25 inches (3 cm) long. It builds a silky, webbed nest as it feeds, usually eating thistle, mallow, malva, hollyhock, sunflower, or canola. As the larva grows, it sheds its skin (this is called molting). The time between sheddings is called an instar; each instar has slightly different coloring.  

Chrysalis (pupa)
: When the caterpillar has grown to the right size, it pupates. It hangs upside-down from a leaf or branch, and attaches itself with a single silken string. An adult forms from the caterpillar, whose internal structure changes completely. The chrysalis becomes almost transparent when the butterfly is about to emerge. An adult will emerge about 7 to 10 days after the chrysalis has formed.

Adult
: When an adult emerges from the split chrysalis, it hangs upside down and pumps blood into its four wings, inflating them.Then it waits for its delicate wings to dry. It
can fly a few hours after emerging.

             Wow! That’s Biodiversity!

Worldwide, there are approximately 28,000 different species (types) of butterflies. 
Students became a scientist who found a new species of butterfly. They needed to
color and name their new species in order to share their discovery with the world. 
With discoveries of the students in Mr. Ritzen’s class, there are now 28,022 species of butterflies in the world. 
            



april_042.jpgBiodiversity is the word we use to describe the variety of like on Earth.

Species is the word we use to organize types of living things. 
For example: Worldwide, there are approximately 28,000 different species (types) of butterflies.

                                                                              Citizenship/Participation  (back to top)

This year students will be on the look out for other people in the class that demonstrate a hard work ethic and have demonstrated the ability to make positive choices.  Every Friday the Rocket Award will be given to a student and their picture will be placed on the classroom website.  During our weekly Friday meeting, the classmates of the Rocket Award winner will have an opportunity to share positive comments and observations about our honaree. All Rocket Award winners get to sign the special book in the office and their family receives a phone call from the principal.

Students are more than welcome to bring in a birthday treat for the class.  The class tradition is the birthday person gets to take the first bite after everyone else is served and sing happy birthday. The birthday person usually prolongs that first bite as long as possible making the others wait with anticipation.
   










                                             

                        Mariah slowly takes the first bite.







                                                                 Class Points

Students can earn a daily sticker for their sticker book if we accomplish everything on our list for the day. Along with the daily sticker ten points are awarded toward the classroom citizenship party. We need to reach 550 points for our party.  We are currently at 550 points for our last session and have an end of the year breakfast on June 16th.  Students can also earn sports and character cards for being consistent in their reading and taking on extra responsibilities.
 Once we have reached our goal we like to celebrate and set a new and higher goal.  

                                                  

september_016.jpg

Students can earn stickers and trading cards by following directions, meeting an academic challenge, studying independently, and by helping the class complete everything on our daily agenda.  Each student has a sticker/trading card folder in which they keep their cache.  On Friday, students are allowed a little time for trading stickers and cards.







 

          
            Nalida and Mikayla make a sticker trade.  

        
                        
                               


                                                                                    


Also on Friday (weather permitting) we will go out for ten minutes to allow students to earn hole punches on a card for each lap around the play field.  Once they have reached ten punches they get a healthy snack (some sort of fruit or vegetable).  Students are learning the importance of exercising their bodies as well as their brains at school. 
















In our computer lab students will learn many skills such as how to copy and paste and navigating and researching on the internet.

The students in Mr. Ritzen's class will be learning to be self-directed learners.   We do this by using the classroom system that emphasizes the importance of checking for accuracy in their work and listening with understanding.  We will really focus on the students becoming self monitors of their own work and behaviors.  We will be  using the following three point rubric that encourages students to evaluate themselves:  (1) Not Yet, (2) Sometimes, or (3) Often.

After reading some poems that were written in our Treasures Antholgy students learned how to write an acrostic poem.  An acrostic poem usese the letters in a topic word to begin each line.  All lines of the poem should relate to or describe the topic word.  Below is the acrostic poem that the class wrote together about winter.
