Instructions: Read each problem with a teacher or helper. Draw or write your answer. Use kind and safe choices.
  1. 1

    Circle the item that belongs in the trash can: a candy wrapper, a flower, or a bird.

    Look for the thing people throw away after eating candy.

    The candy wrapper belongs in the trash can because it is litter and should not be left on the ground.
  2. 2

    You see paper on the playground. What should you do if it is safe to pick up?

    If it is safe, I should pick up the paper and put it in the correct bin.
  3. 3

    Draw one place where litter does not belong.

    Think about a place where you play or walk.

    Litter does not belong on the ground, in water, on the playground, or in a park.
  4. 4

    Choose the cleaner choice: Use a reusable water bottle or throw away many plastic cups.

    Using a reusable water bottle is the cleaner choice because it makes less trash.
  5. 5

    A banana peel is on the floor. Should you touch it with bare hands or ask an adult for help?

    Safety comes first.

    I should ask an adult for help because some trash can be dirty or unsafe to touch.

    Look at the picture. Put an X on the litter.

    The litter is the trash on the ground, such as a wrapper or empty bottle.
  7. 7

    Name one thing you can do to help keep water clean.

    Trash should stay out of water.

    I can keep water clean by putting trash in a bin and not throwing it into rivers, lakes, or drains.
  8. 8

    Which bin should a newspaper go in if your school recycles paper?

    A newspaper should go in the recycling bin if the school recycles paper.

    Finish the sentence: I can keep my classroom clean by ____.

    Think about what you do after snack or art time.

    A friend drops a snack bag on the ground. What kind words could you say?

    I could say, Please put your snack bag in the trash can to help keep our playground clean.
  11. 11

    Circle the things that can hurt animals if left outside: plastic bag, toy car, orange tree.

    Look for trash that can blow away.

    The plastic bag can hurt animals if it is left outside because animals might get stuck in it or try to eat it.
  12. 12

    Draw a clean beach. Add one trash can to your drawing.

    A clean beach has sand and water without litter, and a trash can helps people throw trash away.
  13. 13

    Which action helps the air stay cleaner: walking a short way with an adult or sitting in a car with the engine on?

    Cars can make smoke from their engines.

    Walking a short way with an adult helps the air stay cleaner because it does not make car smoke.
  14. 14

    Sort these items by saying trash or recycle: empty paper box, used tissue, plastic bottle.

    The empty paper box can be recycled if it is clean. The used tissue goes in the trash. The plastic bottle can be recycled if your school accepts it.

    Write or draw one promise you can make to help stop litter.

    Choose one helpful action you can really do.
