About this resource
Description
Place value is the idea that every digit in a number has a job. In the Let’s Make a Number Hundreds Tens One Activity, students learn that the three digits of a three-digit number stand for hundreds, tens, and ones, so 706 means 7 hundreds, 0 tens, and 6 ones. Moving one digit to a new place changes the whole number, and this game makes that idea easy to see and fun to practice.
How to Use This Activity
Each player gets six number cards and a Number Builder Mat with a Hundreds, Tens, and Ones spot. Players pick three cards and place them on the mat to build the greatest number they can. Everyone reads their number out loud, the greatest number wins the round, and players record their numbers on a score card. After six rounds, the player with the most stars wins. Sixteen Challenge Cards add a hundreds tens and ones game for early finishers: build the greatest or least three-digit number from three digits, then check the answer key.
What’s Included
- Colorful cover and a How to Use page with simple steps
- 30 number cards (0 to 9, three of each)
- 16 Challenge Cards (greatest and least numbers)
- Number Builder Mat with hundreds, tens, and ones spots
- Score cards, two per page
- 2nd grade practice worksheet with base-ten models
- Answer keys for the Challenge Cards and the practice worksheet
Why This Activity Helps Kids
First, children connect each digit to its place, which builds the number sense they need for adding and subtracting larger numbers. Second, comparing numbers each round gives quick, repeated practice with greater and less. Third, the game keeps students talking about math, explaining why a 9 belongs in the hundreds place.
Ideas for Teachers and Parents
Use the Let’s Make a Number Hundreds Tens One Activity in a math center, with a small group, or as a family game night at home. For 1st grade, start with the mat and say each place out loud together. For 3rd grade, ask players to write their number in expanded form on the back of the score card. Laminate the mats and cards so the set lasts all year.
