How do you teach first graders to add double-digit numbers?

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.

What are addition strategies for first grade?

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.

Frequently Asked Questions

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).
