Topic D: Subtraction from Numbers to 8

Lesson 23 Concept Development and Problem Set

Noah had 7 red balloons. Two balloons popped as he and his kitties played with them.
Draw Noah’s balloons. How would you show that 2 of them popped in the picture? Can you make a number sentence about your story? Try to draw a number bond to go with it!

Say the number sentence. Fill in the blanks. Cross out the number.
Cross out 2 dots.
Cross out 5 dots.
Cross out 4 dots.

Draw and fill in the number bond and number sentence.
Draw 7 dots. Cross out 2 dots.
Draw 7 dots in a 5-group. Cross out 3 dots.
Draw 7 dots in a 5-group. Cross out 4 dots.

1. Look at the Problem Set. Why is there a 7 at the top of each number bond? Where is the 7 in the number sentence?
2. Which dots is the number seven talking about?
3. Compare with your neighbor the dots you put an X on. Did you put the X on the same dots as your neighbor? Did it change how many dots were left?
4. How can the number bond help you when you are taking away part of a number?
5. How do the number bonds and number sentences go together?

Lesson 23 Homework

Fill in the number sentence and number bond. Cross out 5 dots.
Draw 7 dots. Cross out 3 dots.

Draw 7 dots in a 5-group like the first problem.
Cross out 4 dots.

On the back of your paper, draw 7 dots. Cross out some, and write a number sentence and a number bond to match.
