We did a perimeter question: Hershey's is holding a contest on who can make the best 2D shapes that the perimeter will equal up to 24cm.

My strategy was to use what I know about even numbers. So what I did was I knew 2 was an even number so I counted by two's, 2+2+2+2+2+2+2+2+2, and after that I added a 1 and a 1, then a 4 to equal up 24. And my number sentence was 2+2+2+2+2+2+2+2+2+1+1+4=24. 

Perimeter means the length of an outside object.
