This activity is designed as a self checking math center for students to measure using Unifix cubes, paper clips, inchworms, and rulers (measuring to the inch and half inch). It is a great connection to use between non-standard and standard measurement. Additional supplies needed would be the materials to measure listed above, clothes pins, and stickers to mark the answers on the back. An answer key is provided. My students love these math centers and it is a great comfort to know they are getting the answer right! If you like this activity please check back in the future for additional Clip It centers!
