Multiplication and Division

Mrs. Henderson is placing her family pictures in an album. Each page holds 8 pictures. She has 487 photos. How many pages will be in her album?

*A strip diagram can help with this problem but first you need to know what to do? Are you going to multiply or divide? Do you know the total amount of photos Mrs. Henderson has? If you do, then your answer cannot be greater than her total.

*You also need to remember when we talked about the bus and leaving 8 students behind. Will we need another bus or will we call for another one so the 8 students left over can join us?
