TIMS Challenge

This DPP can serve as Problem of the Week.

1.

The first circle contains numbers which are multiples of 2, 4, and 8. The middle circle contains numbers that are multiples of 2, 3, and 6. The last circle contains numbers that are multiples of 3.

2.

24 and 48 are multiples of 2, 3, 4, 6, and 8.

3–4.

Sets will vary.

N. Add to the Set

Write your answers to the following on a separate sheet of paper.

1. What do the numbers in each circle have in common? Write two more numbers that belong in each circle.
2. Why are 24 and 48 in all three circles?
3. Draw a circle and write your own set of numbers that are alike in one or more ways. Then exchange your circle with a classmate. Ask him or her to add two numbers to the set. Before beginning, think about the different things you have learned about numbers such as primes, factors, multiples, and divisibility rules.
4. Add two numbers to a set of numbers that a classmate wrote in a circle. Explain why your two numbers belong in that set.
