This product is great as a center-- this center is designed in black/white so that it can save ink and be printed on colorful cardstock. Simply print on cardstock, cut, and laminate.
*Rulers not to scale*
Use these cards to help students practice measurement, especially when an object does not start at the end of the ruler. I have my students circle the number where the object begins and ends, and then draw bumps from each inch tick to count how many inches long it is.
