About this resource
Description
The first grade standard 1.OA.2 asks children to solve word problems that add three whole numbers with a sum of 20 or less. This 1.OA.2 Common Core Activity turns that standard into a card-matching game: children read a short story, find the three numbers, and add them by making a ten or a double first.
The pack has 12 Story Cards about everyday things like apples, ducks, crayons, boats and books, and 12 lettered Answer Cards. Every sum is different, so each story matches just one answer. Children read a Story Card, write the number sentence on the Story Log, add, and find the Answer Card with the same sum. This 1st grade addition activity works well in a math center, with partners, or in a small group, and 2nd graders can use it for quick review. A 1st Grade practice worksheet then gives four new story problems with boxes for the three addends and the sum.
What’s Included
- A How to Use page with prep tips, steps and an extension idea
- 12 Story Cards with three-addend word problems (sums 7 to 18)
- 12 lettered Answer Cards
- A Story Log for writing each number sentence and matching letter
- A 1st Grade practice worksheet, a card answer key and a practice answer key
Why Kids Love It
- Matching a story to its answer card feels like a game, not a test.
- Every story has exactly one answer card, so children can check their own work.
- Making a ten or a double first gives children a quick strategy they can use again and again.
Ideas for Teachers and Parents
Before playing, model one story aloud and show how to circle two numbers that make ten. Use the 1.OA.2 Common Core Activity in a math center, then invite children to write their own three-number story for a partner. Keep the cards in a zip-top bag for a quick warm-up all year.
