Lets Practice Here is a ruler broken down into its different parts 1 inch 1/2 1/4 1/8 1 2 3 4

Lets put it together now Here is the same ruler. Now lets go down the line and decide what length I am pointing to. 3 ½ inch 2 1/8 inch ¼ inch 5/8 inch 1 3/8 inch 2 ¾ inch 3 7/8 inch 1 2 3 4

Measuring Number your paper 1-5 and then as the ruler comes up write how big it is. At the end we will be checking them and you will get a quiz grade for today.
