Identify one more or one less of a given 2-digit number with this set of 36 match up cards.

Put on your algebraic thinking caps! 🧙

In our 1 More, 1 Less Match-Up, students will be using their pattern recognition skills to find card combinations that either add or subtract by one.

## Counting One More One Less with 2 Digit Numbers

Use this resource in your math center, as a small group activity, or a whole class exercise (see below) to practice naming the number that is one more or one less of a given 2-digit number.

To play, students will take turns flipping cards to find number pairs that are one more or one less than each other.

## Scaffolding and Extension Tips + Additional One More One Less Activities

Challenge students who already understand the concept to find the numbers that are 10 more or 10 less than the number, or 100 more or 100 less than the number. They can also make their own one more and one less match-up cards using three or four-digit numbers.

Students who need help understanding the concepts can use a number line or a hundreds chart. You can also highlight the digit in the ones place to help students focus on that place value.

Use this resource as independent practice for fast finishers, and for full-class learning opportunities like scoot activities, lesson reviews, formative assessments, and more.

### Jump in the Line

Have students stand up and provide each with a number card. Then challenge them to silently put themselves in numerical order.

### Swat!

During small group instruction, create a grid of 5 cards on top of a table and give each student a fly swatter. Say 1 more or less than a visible card on the table. The first student to swat the corresponding number card sets the card aside in their own pile to keep score. The student with the most cards wins.

### Go Fish

Shuffle the cards and pass out 7 to each player. The remaining cards go in the center of the play area. Taking turns, players ask each other for one more or less than a card in their hand.
