SUGGESTED USES OF MY COLOR BY NUMBERS:1. Use as a classroom assignment when you have time to spare2. Give to early finishers who need a challenge3. Assign as homework4. Use as a fun sub lesson5. Use as a quiz6. Give to students who have ISS (In School Suspension)7. Give to students during a long station activity. Students who finish

their station early can work on the color-by-number. This will help stations flow and minimize behavior problems due to idle time.

8. Save for Fun Fridays or Rainy Days9. Make it a fun group challenge. See below for directions.

There are many different ways you can use my color-by-number activities. Here are some ideas to help you utilize this resource.

GROUP CHALLENGE DIRECTIONS:1. Copy the question sheet and blank coloring page front to back.2. Announce to students:

• “You will be receiving a paper that includes questions regarding the Nitrogen Cycle. Your job is to work in teams to correctly answer the questions. It is important that you discuss each question as a team. Everybody will receive their own question sheet, but all team members should have the exact same answers. If you do not know an answer, make your best educated guess. The team with the most questions answered correctly will get a prize!”

3. Pass one assignment to each student and send them to their team (either assigned or let them choose their teammates). I recommend teams of 3-4 students.

4. Give the class approximately 20-30 minutes to complete the questions.

5. Once time is up, tell students to get out a pen and review the correct answers. I would just allow students to grade their own papers but emphasize that it is important for them to grade honestly.

6. You can give the team with the most correct answers a prize such as early to lunch passes, extra credit, or whatever reward you have on hand.
