Question from Melissa, a parent: suppose you have 60 straws. How many of each shape could you make |
Hi Melissa.
If a straw can only be used for one shape at a time, you can just think of it this way:
(b) There are four sides to a square. So I need four straws for each square. I have 60 straws. So I have to divide them into groups of 4. 60 divided by 4 is 15. So I can make 15 squares.
Try the others now.
Hope this helps,
Stephen La Rocque.
