Students round numbers and use their answers to reveal a mystery riddle! Each task card asks students to round a whole number to a specified place. Students locate and color each answer on the included number grid to uncover the riddle’s solution.

This activity gives students repeated rounding practice in an engaging format while providing an easy way to check their work as the hidden answer appears.

Students will practice:

• Rounding whole numbers
• Rounding to the nearest ten
• Rounding to the nearest hundred
• Using place value to determine rounded values
• Locating answers on a number grid
• Applying rounding skills independently

This activity is ideal for third and fourth grade. Use it for independent practice, partner work, math centers, small-group instruction, or rounding review.
