This is a great way to provide a visual example for counting the days of school to 100. Use the caterpillar body parts to add a number each day and watch the caterpillar grow. I have included clouds that count by 5's and suns that count by 10's. You can create a separate number line for these or place them above the caterpillar body part when you get to the correct numbers.
Please let me know if you have any questions.
