I Can identify and extend patterns and use patterns to solve problems.

**Spark Your Learning**

Burmese cats have about 5 kittens per litter. The number pattern shows the number of kittens in 1, 2, 3, 4, and 5 litters. Choose any number of litters from 6 to 10. Using the pattern below, how many kittens are in the number of litters you chose?

5 10 15 20 25

Make a visual model to show the number pattern.

Answer:

There are 30 kittens in 6 litters.

Explanation:

Given that Burmese cats have about 5 kittens per litter and the number pattern shows the number of kittens in 1, 2, 3, 4, and 5 litters. So there are 30 kittens in 6 litters.
