Great St. Patrick's Day Activity. This product includes 6 shamrock addition practice worksheets with answer keys. The math problems are editable. I recommend you print these double sided to save paper. You could also place these in sheet protectors and have students solve the problems with dry erase markers. They can check their work, erase everything and grab the next one. This could be a center activity. Click the link below to watch my YouTube video on some tips on how to use this product in
