Today, I will work in a small group to apply my knowledge of odd and even numbers.
Materials One student recording sheet for each group. One marker or crayon for each group.
Prep
The recording sheet is divided into 4 sections. Each section is numbered 1-4.
Example:
1
2
3
4
Check for Understanding
Are students able to collaborate in a small group?
Are the students able to skip count by 2s?
Are the students able to pair objects together to see if the number is an odd or even number?
Are students able to articulate what they would do differently to solve the problem? (Error Analysis)

Grade 2 Unit 10 Lesson 3 T TE
Verbal Instruction *MP1: Make sense of the problem and persevere in solving it! *MP8: Find a strategy to help solve the problem.
Section 1 :
Determine whether the number 19 is an odd or even number. Draw a picture to prove your thinking.
Section 2:
Determine whether the number 28 is an odd or even number. Draw a picture to prove your thinking.
Section 3:
The number 20 is an even number. Draw a picture to prove this. Then, write an equation to represent 20 as the sum of two equal addends.
Section 4:
The number 14 is an even number. Draw a picture to prove this. Then, write an equation to represent 14 as the sum of two equal addends.
Group Presentation *MP3: Do you agree/disagree with what
said?
*MP6: How do you know your answers are correct/reasonable?
How did you solve Section 2? Did you have to draw pairs for every number? Why or why not? How did you solve Section 4? What were the two addends? What would you do differently to solve the problem correctly in the future?
Reflective Closure
Were students able to work together as a group?
Were students able to verbalize the mathematical content?
