Question 1

Name one non-standard unit of length.

Accepted Answer

A hand span (or a footstep).

Question 2

How many centimetres are in 1 metre?

Accepted Answer

100 cm.

Question 3

Which is longer: 1 m or 50 cm?

Accepted Answer

1 m, because 100 cm is more than 50 cm.

Question 4

Why do we use standard units like cm and m?

Accepted Answer

Because they give the same measure for everyone, which makes measuring fair and reliable.

Question 5

In a table, 6 children like juice and 4 like milk. How many children in all?

Accepted Answer

6 + 4 = 10 children.

Question 6

Where should you start measuring on a ruler, and why does it matter?

Accepted Answer

Start at the 0 mark; starting elsewhere gives a wrong length because the count would not begin at zero.
