This is a PPT that can be used for comparing numbers. One each slide there are different objects, the student goal is to figure out which group of pictures has more, less, greatest, least, etc. There are ? buttons to click to reveal answers. There is also a lesson on how to use <,>,= signs when comparing numbers (uses 'alligator mouth' example). My 1st graders LOVED this PPT! I am also going to set this PPT up at my computers for a math station activity.
