I edited the file over the weekend to include a couple of bonus pages that will allow you to differentiate your instruction. The bonus pages will allow you to work with students who are only working with numbers to six. They can help the snowmen make six instead of ten.
If you have this file already, pop over to TpT to grab the additional pages. Click on the image below to find it.
Another game in my store - called 'Make 20 and 10 Snowman' will extend your higher level students. You can find it HERE
