Lesson 34 Concept Development and Problem Set

Draw 2 plates. On your first plate, draw 8 grapes. On the next, draw 1 less. Write the numbers below the plates. Now draw 2 cups. In the first cup, draw 6 straws. In the next, draw 1 less. Write the numbers below the cups.

Read the story to the students. Have students cut out the robots. Read the story again as the students glue the robots in the 5-group mat.

10 robots were playing in a circle. 1 robot’s mom called and he had to go home. 10. One less is nine.
9 robots were playing in a circle. 1 robot’s mom called and he had to go home. 9. One less is eight.
8 robots were playing in a circle. 1 robot’s mom called and he had to go home. 8. One less is seven.
7 robots were playing in a circle. 1 robot’s mom called and he had to go home. 7. One less is six.
6 robots were playing in a circle. 1 robot’s mom called and he had to go home. 6. One less is five.
5 robots were playing in a circle. 1 robot’s mom called and he had to go home. 5. One less is four.
4 robots were playing in a circle. 1 robot’s mom called and he had to go home. 4. One less is three.
3 robots were playing in a circle. 1 robot’s mom called and he had to go home. 3. One less is two.
2 robots were playing in a circle. 1 robot’s mom called and he had to go home. 2. One less is one.
And he played happily ever after!

With a partner, take turns telling the story again. Partner 1 says, “10 robots were playing in a circle. 1 robot’s mom called and he had to go home. 10. 1 less is 9.” Then partner 2 says, “9 robots were playing in a circle. 1 robot’s mom called and he had to go home. 9. 1 less is 8.” See how far you can get with the story.

1. How many robots had to go home each time? What happened to the circle when he left?
2. Did you see a pattern after each robot left?
