This activity is about solving word problems related to length.

A pencil is 10 cm long.

A hammer is 30 cm long.

Example 1

How long are 3 pencils and a hammer?

Answer

10 + 10 + 10 + 30 = 60 cm  

Example 2

Which is longer: 4 pencils or 2 hammers?

Answer

4 pencils are 10 + 10 + 10 + 10 = 40 cm  

2 hammers are 30 + 30 = 60 cm

60 is bigger than 40

So, 2 hammers are longer.

Let's try some questions now.
