I don't know about you, but I have a few students, especially my ELL students who are fairly new, who just do not grasp the concept of adding to 10. It gets boring doing the same old thing, so they love anything to do with elves this time of year. Any child can appreciate and have fun with the magic of elves, especially the ones that are not related to Santa. Our elves that visit our classrooms have cousins that work for Santa, but they do not. They are school elves who look out for good behaviors, kind words, special deeds for others, etc.
These math worksheets are done in different forms so that you can differentiate as needed. Also, there is a blank page that you can fill in as you desire, or use as a dice game. If you are interested in me adding frames so children can go up to 20 I will do so, just leave a comment. I have a few more elf items to go up this week, so please return to my site.
