Count on, make ten, and add it up!
First grade is the big addition year. Kids add within 20 using smart strategies instead of counting every single dot: counting on from the bigger number, making ten (8 + 5 = 8 + 2 + 3 = 13), and using doubles they already know. They learn that order does not matter (3 + 9 = 9 + 3), add three numbers, find missing numbers like 6 + ? = 11, and solve story problems. They also add tens and ones within 100. The click moment is when the equal sign stops meaning "the answer goes here" and starts meaning "the same as".
Strategies first, speed later. These moves help 1st graders add with understanding and then with confidence.
Give kids a ten frame and two colors of counters. For 7 + 5, they fill the frame with 7 red, slide 3 yellow in to finish the ten, and see 2 left over: 10 + 2. After a week of building it, kids start doing it in their heads.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.
Try it withAdding to Ten with Fluency WorksheetWorksheetsOpen it →Use a short addition song like adding 1 as a warm-up or a transition. Kids hear the pattern again and again without a worksheet in sight. Songs are especially great for the plus 1 and plus 2 facts that become automatic first.
Why it works: words set to a repeating melody are easier to recall than the same words spoken (Wallace, 1994).

Why it works: the brain holds on to what it meets again and again over time; spaced practice was rated among the very best methods (Dunlosky and colleagues, 2013).

By the end of 1st grade, most kids add within 20 and know facts within 10 by heart. They also add a two-digit number and a one-digit number or a multiple of ten within 100.
Kids break apart one number to fill up a ten. For 9 + 4, they move 1 from the 4 to the 9 to make 10, then add the 3 left over to get 13.
Fingers are fine at first. Teach counting on from the bigger number, then doubles and make-ten facts, and practice a few facts a day. Fingers fade as the facts stick.
It is an equation with a blank in the middle, like 5 + ? = 12. It helps 1st graders see how addition and subtraction are connected.
