Topic E: Decompositions of 9 and 10 into Number Pairs

Lesson 25 Concept Development and Problem Set

There were 9 flowers in Casey’s beautiful garden. She had 2 vases. Draw one way she could have put all of the flowers into the vases. Show your picture to your partner. Did he draw the flowers in the vases the same way? Are both ways right? Are there other ways you could have shown the flowers?

There are 9 shirts. Color some with polka dots and the rest with stripes. Fill in the number bond.
There are 9 flowers. Color some yellow and the rest red. Fill in the number bond.
There are 9 hats. Color some brown and the rest green. Fill in the number bond.
There are 9 jellyfish. Color some blue and the rest a different color. Fill in the number bond.
There are 9 butterflies. Color some butterflies orange and the rest a different color. Fill in the number bond.
Draw 9 balloons. Color some red and the rest blue. Make a number bond to match your drawing.

1. What strategies did you use to fill in the number bonds in the problem set? Did you count each of the parts, or did you think in a different way?
2. How did you figure out how many bears were in the cave during your partner game?
3. How did know you where you should write each part when you were drawing your number bonds on your personal board?
4. Seven bears are sleeping and 2 are in the honey tree. Here is the number bond. What if there were 2 bears sleeping and 7 in the honey tree? Would the number bond change? Does the story change?
5. Thumbs up if you think you are getting really good at putting together and taking apart numbers to 5. (Ask a few addition and subtraction questions such as 3 + 2, 5 – 1, 4 + 1, and 3 – 2.)

Lesson 25 Homework
