Mass, capacity and temperature

For grown-ups: this lesson in words

Years 1 and 2 · Maths

Mass, capacity and temperature: I can measure how heavy, how full and how hot.

1. A melon is heavy. It weighs a lot.

   A leaf is light. It weighs very little.

   A brick is heavy. A balloon is light.

   Picture: Sorting into 2 groups: Heavy, Light. Heavy: Melon, Brick. Light: Leaf, Balloon.

2. Your turn: Which is heavier?

   Choose one:

   • mouse: mouse
   • elephant: elephant

   Answer

   The answer: elephant

   The elephant weighs more, so it is heavier. The mouse is lighter.

3. Here is a jug. It is empty.

   Now it is full. It holds 2 litres.

   Picture: A measuring jug from 0 to 2 litres, labelled every 1, with a mark at every label. It shows 2 litres. It went from 0 litres to 2 litres.
