What this lesson shows
36 strings of 250 centimeters from 30-meter rolls: 9,000 centimeters is 90 meters, so 3 rolls.
The worked example
The lesson works this one step by step: 36 pieces of 250 cm from 30 m rolls. Then your kid tries one like it on paper.
The steps
- Find the total
- Change units
- Answer in that unit
Helping at home
Find the total in one unit, then change it to the unit the question uses: 100 centimeters make 1 meter, so divide by 100. Then answer the question in that unit.
If your kid gets stuck
Change to one unit first.
