Lesson 27 Concept Development and Problem Set

You are having a birthday party! You need to have 10 party hats for your friends. Draw 10 simple hats. Color some hats red and some blue. Make a number bond about your picture. Turn and talk with your partner. Do your pictures look the same? Explain to your partner how you decided which way to color your hats. Talk about how your number bonds are the same or different.

Benjamin had 10 bananas. He dropped some of the bananas. Fill in the number bond to show Benjamin’s bananas.
Savannah had 10 pairs of glasses. 5 are green and the rest are purple. Color and fill in the number bond.
Create your own 9-cube stick and fill in the number bond to match.
Xavier had 10 baseballs. Some were white and the rest were gray. Draw the balls and color to show how many may be white and gray. Fill in the number bond.
There were 10 dragons playing. Some were flying and some were running. Draw the dragons. Fill in the number bond.
Create your own story of 10. Draw your story and a number bond to go with it.

1. Look at the baseball problem. How did you know which numbers to write in the parts of the number bond? Are there other ways you could have done it?
2. What strategies did you use when you were making up your own story?
3. How did the bracelets help in finding the partners to 10?
4. Who can use this bracelet to teach someone how to make number bonds at home tonight? Tell me how you will do it.
