Students will love counting the footballs and matching the amount to the correct number. These puzzles are self-checking because the pieces can only match up to the correct answer. It includes puzzles for number 0-20. This is a great activity to include as a math center or even use it as a pocket chart activity or an assessment. All you have to do is print, laminate, and cut the cards apart. You can find more freebies, such as this, on my blog at http://lessonplansandlollipops.blogspot.com/
