Measurement is a subject that can be easily overlooked but is very important for developing real life skills. Within the National Curriculum measurement includes measuring length, mass, temperature and volume/capacity. But it also includes money and time. For several year groups we have separate categories for money and time as they are each large topics in themselves.
Three very different aspects of measurement are the subject of our latest sets of worksheets for Year 4 children. The first looks at tricky mass/weight problems.
A typical example is:
An apple and a pear weigh 210 g.
Two apples and a pear weigh 0.305 kg
1. How much does one apple weigh in grams?
2. How much does one pear weigh in grams?
Why is this tricky?
For two main reasons.
Firstly, the weights are given in grams and kilograms and need converting to the same unit – in this case grams would make more sense.
Secondly the second answer can only be worked out if the first has been answered correctly.
These questions are typical of the type being promoted by ‘Mastery of Maths’ advocates and they certainly make children think about what they need to do to reach an answer.
The second set of worksheets takes a look at negative numbers in the context of reading thermometers or number lines.
The third set is all about converting minutes to hours and minutes and vice versa, again a process that needs two steps; dividing by 60 and working out remainders (or multiplying by 60 and adding).
