Lesson details
Key learning points
- Using the known fact that 100 cm are equivalent to 1 m can help us convert between cm and m.
- Partitioning and using the relationship between 1 m and 100 cm can help us convert between cm, and m and cm.
- It is always important to estimate so you know if your answer is near to the real value.
Keywords
Equivalent - When something is equivalent, it is equal in value.
Convert - When we convert, we change the unit of measurement between metres and centimetres, but the value remains the same.
Common misconception
Some children may think that 300 cm is bigger than 3 m because 300 is a bigger number than 3.
1 m is equivalent to 100 cm. So 3 m is equivalent to 300 cm. 3 m and 300 cm are equal in length or height.
