How to Play the Multiply km and m Game

1. Read the Problem
   The game displays a distance in kilometers (km) and meters (m), along with a multiplier (the number of times that route is traveled).
   Example: 12 km 450 m multiplied by 3.
   

2. Multiply the Meters
   Start by multiplying the meter number by your multiplier.
   450 m × 3 = 1,350 m.
   

3. Regroup
   In the metric system, 1,000 meters = 1 kilometer.
   If your meter total is 1,000 or more, “bundle” the thousands into kilometers.
   Take 1,350 m. Since there is a “1” in the thousands place, it becomes 1 km and 350 m.
   

4. Multiply the Kilometers
   Now, multiply the original kilometer number by the multiplier.
   12 km × 3 = 36 km.
   

5. Final Arrival
   Add the kilometers you “carried over” from Step 3 to your kilometer product.
   36 km + 1 km (carried) = 37 km.
   Final Answer: 37 km and 350 m.
   

Example:
Problem: 5 km 600 m × 2
Multiply meters: 600 × 2 = 1,200 m.
Regroup meters: 1,200 m becomes 1 km and 200 m.
Multiply km: 5 × 2 = 10 km.
Add Carry: 10 + 1 = 11 km.
Result: 11 km 200 m.
