Common Mistakes

MISTAKE: Counting incorrectly, like starting from 7 and counting 7 as the first step (making it 7, 8, 9, ... 13) | CORRECTION: When adding 7 to 7, start counting from the number *after* 7. So, it should be 8, 9, 10, 11, 12, 13, 14 (seven steps).

MISTAKE: Confusing addition with subtraction, and thinking 7 + 7 might be 0 | CORRECTION: Remember the '+' symbol means to combine and make a bigger number, not to take away. The answer will always be greater than or equal to the numbers you started with.

MISTAKE: Forgetting to count all the steps or numbers when adding | CORRECTION: Use fingers, draw dots, or imagine objects to keep track of each number you are adding. Double-check your count to ensure accuracy.
