ACTIVITY: To estimate, measure and record the mass of 2-dimensional shapes and to use appropriate measuring instruments [LO 4.6.1]

To use appropriate measuring instruments [LO 4.6.1]

1. Have you ever paused to think about how many things we pick up and carry around with us every day? You can say whether something is heavy or light, but have you ever wondered what the mass of a particular article is, that you are carrying? Let us look at a couple of examples. Complete the following table. First estimate and then determine the exact mass. Use a kitchen scale!

Table 1
Item Mass in gram
  Estimated Measured
1.1 tin of cool drink _____________________ _____________________
1.2 hairbrush _____________________ _____________________
1.3 pencil box _____________________ _____________________
1.4 Mathematics book _____________________ _____________________
