Doubles Facts Practice

Work the example at the top of the page together, then let your child try the first problem alone. Ask which strategy they used and why it fits the numbers. If a strategy feels slow, go back to the ten frame or number line page for that skill.

Add doubles within 20, then find the double for each total. Doubles are addition facts that add the same number twice, like 4 + 4. Problems on the page include 2 + 2, 7 + 7 and 3 + 3. The directions on the page read: Add to find each double. Then, find the double for each total and write the same number in both boxes. The page opens with a worked example, and the answer key shows every answer.

Yes, both. We made it for 1st Grade addition, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with addition strategies. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

The main ones are counting on, making ten, and using doubles and near doubles. Each gives a quick way to find a sum within 20 without counting every object from one.

For 8 + 5, take 2 from the 5 to make 8 + 2 = 10, then add the 3 that are left to get 13. The make ten sheet gives boxes for each step so students can see the ten.

A near double is a fact like 6 + 7. Double the smaller number (6 + 6 = 12), then add 1 more to get 13. Knowing doubles well makes near doubles quick.

They support 1.OA.C.6, which asks students to add within 20 using strategies such as counting on, making ten, and doubles and near doubles.

By the end of first grade, students should fluently add within 10 (CCSS 1.OA.C.6) and solve addition problems within 20 using strategies like counting on, making ten, and decomposing numbers. They should also add within 100 using place value understanding (1.NBT.C.4).

Start with adding a two-digit number and a one-digit number, then progress to two two-digit numbers. Use place value understanding: add the tens first, then the ones. Base-ten blocks and place value worksheets make this concrete before moving to abstract equations.

Key strategies include counting on from the larger number, making a ten (e.g., 8+5 becomes 8+2+3), using doubles (6+6=12) and near-doubles (6+7=6+6+1), and decomposing to known facts. Worksheets that practice each strategy separately help students build fluency.
