Adding Within 20
Grade 1 · Math · Addition · Indiana, USA
Lesson Summary
Practice adding two numbers that give a sum up to 20.
Explanation
Now that you can add small numbers, it is time to work with bigger ones. When you add numbers that go past 10, you can break one number apart to make a 10 first. For example, 8 + 5 can become 8 + 2 + 3, which is 10 + 3 = 13. This trick of making a 10 helps you add faster and more accurately.
