An addition table can help you memorize sums.

Can you use the table to find the sum for 2 + 4?

Then draw a line from the 4 going to the right .

Stop at the number where the two lines meet. That's the sum of 2 and 4, 6!

We can write our answer as an addition equation like this:

Adding by 1 is like skip counting up by 1.

We use addition to put numbers together to make a sum.

Adding by 2 is like skip counting up by 2.

Can you figure out all the pairs of numbers that add up to 10 using this addition table?

Tip: The = is an equals sign. It means that what's on its left  is equal to what's on its right .

Now, start the practice. Once you're done, you'll have your addition table memorized.

Tip: When you show two things are equal with an equal sign, =, you're writing what math people call an equation.

You can think about addition like counting up on a number line.

If we start at 2 and count up 4, we get 6.

This is the same as the addition equation 2 + 4 = 6.

Now that you understand addition, the next step is for you to memorize the sums up to 10.
