CalcMonkey › Kids math games › 1st grade
First graders are discovering that numbers can be put together and taken apart. These free games give them lots of quick, playful practice adding and subtracting within 10, then stretch to 20 on the number line and into tens and ones. Every right answer earns a banana for their monkey, Mochi, and bananas unlock dress-up outfits and adventures.
Catch the banana with the right answer to facts like 6 + 3 and 9 − 4.
Play ▶Pop the balloon with the answer before time runs out.
Play ▶Each right answer hops your monkey closer to beating the parrot.
Play ▶Drag each banana to the monkey whose problem it answers.
Play ▶Hop forward to add and backward to subtract, all the way to 20.
Play ▶Build numbers like 34 from bunches of 10 bananas and single bananas.
Play ▶🎪 Eight more ways to practice the same facts: Vine Swing, Ice Cream Tower, Present Surprise, Ski Lift, Penalty Kicks, Sing-Along, Planet Hop and Crown Jewels.
These games line up with these Common Core State Standards for Mathematics:
In most U.S. schools, first graders learn to add and subtract within 20 (with quick recall within 10), understand tens and ones in two-digit numbers, compare numbers, and solve simple story problems.
Start with strategies — counting on, doubles like 4 + 4, and making ten — then practice a few minutes every day. The quick-fact games here mix addition and subtraction so kids also see how the two connect.
