Lesson 9.3

Possible or Impossible

Read the story. Circle possible or impossible.

1. Jake pulled 9 from the bag.

possible impossible

2. It is impossible to pull a purple crayon.

3. Draw 6 . Color them

so that is it possible to

pull an orange but

impossible to pull a

blue .

Color the crayons to make the story true.

Draw and color to solve.

Stretch Your Thinking Draw a bag with 6 marbles in it. Then write your own problem like Exercise 3.

Check childrens work. Children must not color any of the crayons purple.

Check childrens drawings. Children must color at least 1 ball orange and color no balls blue.

Check childrens work. Pictures will vary.
