In this practical task, students estimate, and then measure, the weight of two objects using a number of multi-link cubes, a balance scale and weights.
This practical task requires students to lift a 1 kg weight and then estimate whether a range of everyday objects weigh less than, about the same as, or more than 1 kilogram.
From diagrams of four original and enlarged drawings to be used for Christmas wrapping paper, students identify the scale factor used and find a missing length on either the enlarged picture or the original picture.
From three different sized animal pictures and their enlargements, students are required to identify the scale factor and the length of an unknown side.
