This product contains 28 clip cards. Each card has an subtraction sentence (from 10 or less). The child can use the number line at the top of each card to solve and then clip the correct answer. Just print, laminate and cut out. You will need mini clothespins. I like to store mine in a plastic sandwich container. These are great activities for early finishers, math dessert and/or math centers. If you would like to make them self-checking, just add a dot or a sticker behind the correct answer.
Hope you find them useful in your classroom! Feedback is always appreciated! Enjoy!
