Patterns in Addition and Subtraction Facts

These are charts I created to help my students with those tricky Addition and Subtraction Facts. What we would do is first write in the answers to each fact that we know right away (the easy ones). Then we would highlight the facts that we don't know right away (the hard ones). Then, we would fill in the answers to the hard ones by looking for patterns. It's really easy for them to see patterns using this kind of chart. Looking for patterns helps in understanding number sense instead of just memorizing the facts.
