    Indentifying even and odd numbers

    Indentifying even and odd numbers

    Overview

    This is a lesson plan will introduce 2nd graders to the concept of odd and even numbers through a fun story called Even Steven and Odd Todd.  Students will learn to pair manipulatives and count by 2's to see the difference between odd and even numbers.

    Background for Teachers

    Materials

     1.   Video on utube:  Even Steven and Odd Todd by Kathryn Cristaldi:  https://www.youtube.com/watch?         v=EdvpZYNmLqc&t=2s

     2.    30 small counters for each student (lima beans, cheerios)

     3.   Two pieces of construction paper for each student. (One colored and one white.) 

     4.   1 small whiteboard and a black marker for each student.

     5.   crayons, markers, or colored pencils for each student

    Learning Objectives

    Step 1 Goals and Outcomes

    State Standards:  2.OA.3 Operations and Algebraic Thinking,  Determine whether a group of objects (up to 20) has an odd or even number of members, (for example, by pairing objects or counting them by twos).

    Learning Intentions:

    Students will be able to identify a number as odd or even by pairing a group of up to 20 objects and counting them by two's. 

    Success Criteria: 

    Students will independently draw twenty pictures in groups of two or circle the 20 pictures into groups of two, count them by 2's and identify if the number is odd or even.

       

               

     

            

     

    Planning Instruction

      Students background knowledge:

     1.  Count objects up to 20 and write the number 

     2.  Draw 20 pictures in groups of two's.

     3.  Count by twos to 20 accurately or use a hundred's chart with the counting by 2's highlighted to count by 2's

     4.  Put 20 drawn pictures into groups of two's by circling them

     Strategies for diverse learners:

    1.  Students can use a 100's chart with the counting by 2's numbers highlighted to twenty to help them count.       

    2.  Students will be able to choose more than 20  beans during the independent activity.

    3.  Students will be able to choose to draw more than 20 objects to draw for the final assignment.

    4.  Students may circle pictures into groups of two on the final assessment

         

     

     

    Instruction

    Step 3 Instruction

     

    Teach:

    Before watching the video have students listen for the numbers that Even Steven and Odd Todd like.

    Watch the video of the book  Even Steven and Odd Todd by Kathryn Cristaldi  pausing several times to generate a list of things each boy likes including the number. 

    https://www.youtube.com/watch?v=EdvpZYNmLqc&t=2s

    After the video, ask the students to think about what the difference is between even numbers and odd numbers. Guide students to recognize that even numbers are counting by two’s numbers.

    Model with counters that even numbers can be grouped by two’s equally and odd numbers cannot.  You could teach that odd numbers always have one “ odd ball”  left over when you group them into two’s.

    (The video "Numberblocks Odd vs Even" may be used here if desired.) 

    Guided Activity:

    Have students see if they can find groups of things in the classroom that Even Steven would like and things Odd Todd would like and share their findings. 

    Next model under a document camera how to take the amount of beans they would like to use and put them on a workmat (colored piece of contruction paper). Next group the beans into two’s until all of the beans have been paired evenly or there is one left over.  Have the students silently count the beans by 2's, write the number on their whiteboard and if it is odd or even.  The students should keep their answer hidden until you ask them to show it. Count the beans with the students to see if they were correct.  Do this several times.   

    Independent Activity 

    Now have the students repeat this activity a few more times independently with some beans, a workmat, and a whiteboard at their desks.  Walk around and observe for understanding of the concept.  

    Assessment:

    Model for students how to do this final assignment.

    Give each student a piece of white construction paper.  Have them fold it in half and write Even Steven on the top of one half and Odd Todd on the top of the other half.

    Students will pick something to draw for Even Steven and something for Odd Todd like flowers, cookies, diamonds, hearts-anything that will be easy for them to draw in pairs. Once they have drawn as many objects in pairs as they would like, they will count them by two’s and write the number under Even Steven or Odd Todd.  

     

     

     

     


     

     

     

     

    Assessments

    Step 4 Assessments

    Formative Assessments:

    Students will be able to identify odd and even numbers correctly during the guided activities and independent activities.

    Summative Assessment

    Students will be able to complete a drawing of 20 pictures grouped by 2's evenly and  unevenly (one left over) write the number, and indentify if the number is odd or even.

    Students will be able to draw 20 pictures, circle them into groups of 2's evenly and unevenly, write the number and identify if the number is odd or even.
