Using rulers

This activity is one I created for my little guys to introduce the concept of using a ruler. Each page has a ruler and an object already placed on it as well as a line to reference where the child should be looking to find out how long it is. When a student selects the correct number (for its placement on the ruler) it has a reinforcing sound. It ends with a few pages of "which one is the longest/shortest" to help reinforce the topic.
