  2. Let’s start with something easy! 6 3 + 3 = Now, let’s learn some new words. 3 + 3 = 6 The numbers you are adding are called addends.The answer is called the sum.

  3. You can check a Math problem to see if your answer is correct. 3 + 3 = 6to , Subtract one of the addends from the sum. The answer should be the other addend. If not, try again. 6 – 3 = 3

  4. Try this: 14 7 + 7 = Now let’s it! 14 – 7 = 7 CORRECT!

  5. Now, try these: 4 + 4 = 6 + 6 = 8 + 8 = 5 + 5 = 2 + 2 = 9 + 9 = Now, let’s them.

  6. 8 - 4 = 12 - 6 = 16 - 8 = 10 - 5 = 18 - 9 = 4 - 2 =

  7. Are you correct? 4 + 4 = 8 6 + 6 = 12 8 + 8= 16 5 + 5 = 10 2 + 2 = 4 9 + 9 = 18 WAY 2 Go!
