## Envision Math Common Core Grade K Answers Key Topic 11 Count Numbers to 100

Essential Question
How can numbers to 100 be counted using a hundred chart?

enVision’STEM Project: Ant Colonies
Directions Read the character speech bubbles to students. Find Out! Have students find out how ants live and work together in colonies. Say: Talk to friends and relatives about ant colonies. Ask about the different jobs ants in a colony might have that help them survive. Journal: Make a Poster Have students make a poster. Have them draw an ant colony with 5 groups of ants. There should be 10 ants in each group. Then have them count by tens to find how many ants there are in all. Hove students use a hundred chart to practice counting by tens to 50.
