Subtraction with Regrouping

To help those students who are struggling with the concept of subtraction or addition with regrouping. Many times this occurs simply because the concept is to generalized and broad form them. After trying the mommy, daddy, child story or "Do I have enough chairs?"  I created this little booklet out of paper to help students fully understand what is occurring when they are subtracting with regrouping. 



1. Take 4 pieces of paper, after creating my model I used laminated construction paper to make the booklets. 
2. Fold the 4 pieces of paper into 4 rectangular pieces. 
3. Stagger the pieces of paper on top of each other. 
4. Using the top piece of paper as a guide cut the piece of paper in half (opposite of the folds). 
5. Cut the halves along the folded creases. 
6. Staple the 8 booklets. 

 

7. Write the problem with each color of the paper to be a different place. (If the paper was laminated use an expo marker). 
8. Solve the problem by using one of the riddles of your choice.
9. Once students borrow they can solve the problem on the side to "see" what they are subtracting.
10. Once the entire problem is solved one value at a time the booklet closes to show the actual problem and the process for solving it.
11. Student's write the steps that they took to solve the problem.
