Bowling!

1. Bowling! Students in a grade 7 class were raising money for charity. Some students had a “bowl-a-thon”. This table shows the money that one student raised for different bowling times. What patterns do you see in the table? How long would the student have to bowl to raise $72?

2. Divisibility Rules What is meant by “divisibility rules”? A way to divide numbers quickly by following a pattern. Why is it important? Divisibility rules help us find the factors of a number.

3. Copy down the following numbers. Circle the ones that are divisible by 2. Place a square around the ones that are divisible by 5. Draw a triangle around the ones that divisible by 10.

5. Activity: Hundred's Chart • Choose 3 different colors. • Using one color, circle the numbers that are divisible by 2. • 3) Using a different color, circle all the numbers that are divisible by 4. • 4) Using your last color, circle all the numbers that are divisible by 8. Be able to discuss the following: Describe the patterns that you found.

6. Carroll and Venn Diagrams Sort the following numbers based on the divisibility rules for 3 and 5 using both Carroll and Venn Diagrams. 6, 8, 10, 15, 18, 25, 26, 36, 40, 45, 120
