Counting on is a simple addition strategy where you start with the larger number and then count up by the smaller number. When adding 1, 2, or 3, this method is quick and easy. For example, to solve $5 + 2$, start at 5 and count on 2 more: 6, 7. So, $5 + 2 = 7$. It's like using a number line in your head! You can also use your fingers if it helps!
This worksheet will help you practice counting on with 1, 2, and 3. Get ready to become a counting-on superstar!
