This game helps students practice multiplying by 10, 100, and 1,000 in a hands-on and engaging way. By rolling the die and multiplying different numbers each time, they’re challenged to think critically about place value shifts and develop fluency with these operations in a fun, interactive setting.
Objective:
Students will practice multiplying numbers by 10, 100, or 1,000 using a fun, interactive game that reinforces the concept of place value shifts.
Materials:
- Dice (1 six-sided die per pair or group)
- Index cards or paper slips with numbers (ranging from 1 to 999)
- Large place value chart (optional)
- Dry-erase boards and markers (or scratch paper)
- Multiplication mats (simple charts showing x10, x100, and x1,000 columns)
How to Play:
1. Setup: Create a set of number cards by writing different numbers (from 1 to 999) on index cards or slips of paper. Shuffle and place these in a pile. Each student or group needs a dry-erase board (or paper) and a die.
2. Roll for Power: Each player/group rolls the die. The number they roll determines the multiplier:
- Roll a 1 or 2 = Multiply by 10
- Roll a 3 or 4 = Multiply by 100
- Roll a 5 or 6 = Multiply by 1,000
3. Pick a Number: The player draws a number card from the pile.
4. Power Up the Number: Using the dry-erase board or scratch paper, the player writes the number they drew and multiplies it by the number of powers determined by their die roll. For example, if they drew "34" and rolled a "3" (multiply by 100), they would calculate: 34 x 100 = 3,400.
5. Show Your Work: Players must explain how they arrived at their answer by discussing how the digits shifted when multiplying by 10, 100, or 1,000. Encourage them to think about moving digits left and filling in zeros as placeholders.
6. Earn Points: Correct answers earn 1 point. Bonus points (1 extra) can be given if the player provides a clear explanation of how the place value shifted.
7. Repeat: Play continues with students drawing new number cards and rolling the die. The first player or group to reach 10 points wins.
Optional Variations:
- Challenge Level: Add in decimals to increase difficulty, having students multiply numbers like 4.2 or 13.75 by 10, 100, or 1,000.
- Relay Race: Set this up as a team game where students must race to complete each step (draw, roll, multiply) and then pass the board to the next teammate.
- Craft Version: Have students create and decorate their own “power-up” dice with fun, colorful designs representing each multiplier (x10, x100, x1,000).
