Adding 1 to a number takes you to the next highest number on the number line. For example, 2 + 1 = 3. Any number added to zero equals the same number because "zero" is the same as "nothing." Doubles are problems that involve adding two of the same number. For example, 3 + 3 = 6 is an example of an equation involving doubles. In the example below, you learn through mapping what happens when you add 3 to 5, 2 and 1. Try the "add 2" problems on your own. Learn to add 3 numbers together to get a number larger than 10. Learn about regrouping 1s into the 10s place, 10s into the 100s place, etc.  Add the numbers in the right column first. 8 + 4 = 12, which means you have 1 10 and 2 1s. Write down the 2 under the 1s column. Write the 1 over the 10s column. Add the 10s column together.
