Students solve number comparison cards and use their answers to uncover a mystery riddle! This interactive activity combines numbers to 20 practice with a motivating riddle format that keeps students engaged as they review.

Students can use connecting cubes or other math manipulatives to model the numbers, compare quantities, and cover the correct answers on the included recording mat.

Students will practice:

• Comparing numbers to 20
• Identifying which number is greater
• Identifying which number is less
• Using number sense to solve comparisons
• Representing numbers with manipulatives
• Recording answers to reveal a riddle

This activity is designed for kindergarten and first grade. Use it for whole-group practice, small-group instruction, partner work, or an independent math center.
