I created this for my kindergarteners to practice their addition. Differences range from 1-9 and they color accordingly once the math is completed. I like color by subtraction because my students are all at different levels when it comes to subtraction skills. Some can already do all of these math problems mentally, and others use their fingers or their numberline. This activity is wonderful for numberline practice! The best part is that since students get to color the St. Patrick's Day picture after the math is complete, they look at it as something fun to do and don't even realize that they're practicing their math facts!
If you like this one, be sure to grab my color by addition version as well! Enjoy!
