Now that your kids are all warmed up it’s time for them to recognize number patterns. Start by providing each student with a hundreds chart and clear chips. If you don’t have clear chips…. no problem… simply laminate the boards and give each student dry erase markers. Students should work in pairs during this activity to explore and discover different number patterns.

#### Discovering Number Patterns – Skip Counting by 5’s

When you first introduce students to this activity it’s important to start with familiar numbers. Ask students to place clear chips on the following numbers: 5, 10, 15, 20, 25, 30. Then give them time to discuss patterns they notice with a partner.

Several students may notice that each number ends with a 0 or 5. They may also notice that they are five numbers apart. After students discuss with their partner, select a few to share with the class.

Give students another opportunity to place clear chips on familiar numbers like: 45, 50, 55, 60, 65, 70. Continue the same process as above.

#### Important Questions to Ask During this activity include:

- What patterns do you notice?
- How did you see these patterns? Prove it by showing it to us.
- What do you think will happen if I change the first number from 45 to 44? Will the pattern remain the same or will it change? Will you still skip count by the same amount?
- Do you notice any patterns with the digits in the numbers? What are they?

To wrap up, allow students to create their own patterns that skip count by 5.

On another day, allow time for students to look at less conventional patterns that skip count by 5’s like 23, 28, 33, 38, 43 and 48 (check out the picture below). Use the same guiding questions from above to provide meaningful discussions.

Remember the most important part of this activity is to allow your students time to discuss the patterns they notice.

Now apply the same process when skip counting by 10’s.

This wraps up 3 engaging ways to use hundred charts. Be sure to check out part two of this post. In that post I share three more helpful ideas for implementing hundred activities in your class.
