Learn about measuring mass using non-standard measures.

This lesson includes:

  • two slideshows
  • two activities

Created in partnership with Twinkl.

Learn

Begin by taking a look at the slideshow to help you understand how to measure with non-standard units of measurements.

A balance scale has been set up in the classroom to compare the weights of different objects. Click through the slideshow to see how to balance the objects.

A set of empty balance scales on a desk in a class room.

When both sides of the scales are the same height, this means the scales are balanced because the mass is equal on both sides. We usually use the words 'weigh' and 'weight' when we are talking about mass.

Have a look at this other slideshow to see another example of comparing the mass of different objects.

A set of balance scales weighed down on one side by a glue stick and two rubbers on the table.

This time the fruit has been changed to a glue stick and rubbers. How many rubbers do you think the glue stick will weigh?

Practise

Use these activities to help further develop your understanding of measuring mass.

Activity 1

The first activity builds on using more non-standards units of measurements to compare the weights of different objects. This activity requires a helping hand from a parent or guardian.

Take a look at the answer sheet when you've done.

Activity 2

Now, why not try creating your own playdough using a simple recipe? This activity is aimed to help you measure with standard units.
