This document discusses multiples and using a hundreds chart to solve problems about callers winning prizes in a radio contest. It explains that the 6th caller would not win a prize because 6 is not a multiple of 3 or 7. The 14th caller would win a hat since 14 is a multiple of 7. A hundreds chart is used to circle the multiples of 3 for t-shirts and cross the multiples of 7 for hats. More callers will likely win t-shirts since there are more multiples of 3 than 7 in the lower numbers. Key learnings are that multiples are found by counting on by the given number and a common multiple is a number that is a multiple of two or more numbers.

Unit 2 exploring multiples
- 1. Math 6:Whole Numbers Exploring Multiples
- 2. Getting started A local radio satiation held a call-in contest. Every 3rd caller won a t-shirt Every seventh caller won a baseball hat. Suppose to were the sixth caller. Would you win prize? How do you know? Would you win a prize if you were the 14th caller? How do you know?
- 3. Hundreds Chart You can use the hundred chart to help solve the problem! But how? – Draw on the board Circle the 3’s and X the 7th caller
- 4. Explore Why does the 21 have both colours on it? Common multiple Do you think more callers will winT-shirts or hats? Explain.
- 5. Hundreds Chart Count by 4. These are known as multiples of 4!
- 6. Key Math Learning 1)The multiples of a number can be found by starting at the number and counting on by that number 2) A common multiple is a number that is a multiple of each of two or more given numbers.
