Let's use bar models to subtract! Follow the directions and complete the activities.

Bar models are like number puzzles made with blocks! The big block sitting on top shows the whole amount. Under it are smaller blocks that show the parts. Sometimes there are two parts, and sometimes there are more. If you know the whole and all the other parts, you can use subtraction to figure out the missing one. Why do we learn bar models? Because turning a math problem into a picture helps us see the numbers and solve it faster. Want to give it a try? Grab your pencil, and let's explore!
