Lesson 11 Concept Development and Problem Set

Mary has 10 toy trucks. She told her mom she likes to spread them out on the floor. She said she doesn’t like to put them away neatly in the little toy box because then there are fewer toys. Can you draw a picture to prove to Mary that the number of toy trucks is the same when they are all spread out as when they are in the little toy box?

1. What do you notice when you look at your paper?
3. How many cubes did you put on your tower each time?
4. Did the number get bigger or smaller when you put one more?
How is the number tower you made the same as the Rekenrek you made? How is it different? 5. Fold your paper in half and look just at the green stairs. How are they the same and different than the stairs for the bigger numbers?

Lesson 11 Homework

Write the missing numbers. Then count and draw X’s and O’s to complete the pattern.
