Addition combines two or more amounts to find the total (the sum).
In class: Start by counting on from the larger number, then move to partitioning into tens and ones and adding each part, and finally column addition with regrouping.
This Grade 3 addition set is free to print or save as a PDF, and its answer key is computed in code, so it is never wrong.
