These clip cards are a great way for students to practice their knowledge of one less using a multiple choice system. 43 cards are included which cover the concept of one less using various visual representations, with missing addends and on a number line. Each card has three possible answers. Students select the correct answer by clipping a clothespin, peg or paper clip to it. I like to laminate these cards so students can simply circle the correct answer using a dry erase marker. Alternatively, you can print these on paper to hand out to your class at the end of the lesson; pupils circle the correct answer and hand in as a great exit ticket or plenary to the lesson.
