Last week we learned about prime and composite numbers. Please write a definition for prime numbers and list all the prime numbers from 1-100 (hint: look at the sieve of Eratosthenes). Please also write a definition for a composite number and give five examples.  We also talked about the number one. What did we say about it?

The easiest way to find the total number of items in equal groups is to use multiplication. Multiplication allows you to do repeated addition quickly and efficiently.

Write a multiplication word problem using two of the following factors: 75, 12,  34, 15, or 23.    For example:  Joe sold 75 boxes of candy for a fundraiser.  Each box was sold for $12.  How much money did Joe raise?
