FREE MATH LESSON – “FREE Place Value Game | Decomposing in More than One Way | 2nd Grade”
by Math Coach’s Corner
1st – 3rd Grade
⭐ Give students the chance to decompose two-digit numbers in more than one way while working with a partner in this engaging place value game! In Closest to 200, students roll dice, decide how to arrange the digits to create a two-digit number, and strategically try to get as close to 200 as possible after five rounds. They model each number with base-10 blocks in more than one way, encouraging hands-on learning and math talk. This partner game is perfect for math centers and helps students compose and decompose numbers flexibly while also building problem-solving and decision-making skills.
✨ Why it matters
Being able to compose and decompose numbers in more than one way builds deep place value understanding and number flexibility—skills that support addition, subtraction, and mental math. Adding a layer of strategy helps students think critically and make intentional choices about numbers.
✨ How it helps
This resource turns abstract place value ideas into meaningful, engaging practice. Students not only model numbers in multiple ways but also reason about which numbers will get them closer to the goal—encouraging strategic thinking, comparison, and discussion.
✨ Ways to use
- Math centers to encourage partner collaboration and strategy talk
- Small-group lessons for targeted place value instruction
- Whole-class modeling and shared problem-solving
- Intervention or enrichment to develop flexible number sense
✨ What’s included
- Student recording game sheet
- Teacher directions for easy prep
