This winter themed SMARTBOARD lesson will allow students a fun opportunity to practice their basic addition facts with sums from 9-20. All slides are self checking by clicking on the snowman at the bottom of the slide. Students are presented with 3 numbers for the first addend and 3 different numbers for the second addend. They must put the two numbers together to equal the sum that is given. This can easily be used as a whole class activity, a game, a small group activity, or even independently in a center or station. It may also be used over and over as reinforcement. Created with Smart Notebook 11. Great for grades 1-5 as introduction, practice, or review to sharpen their basic addition skills.
