# Standing Order

Purpose

The purpose of this activity is to engage students in applying their number knowledge to compare measurements of the same type but given in different formats.

Achievement Objectives
GM3-1: Use linear scales and whole numbers of metric units for length, area, volume and capacity, weight (mass), angle, temperature, and time.
NA3-1: Use a range of additive and simple multiplicative strategies with whole numbers, fractions, decimals, and percentages.
Description of Mathematics

In readiness for this problem, the students should have familiarity with each of the following components of mathematics. The problem may be solved with different combinations of these components.

• metric units of length
• converting between cm and m
• fractions
• decimal place value
• ordering values

This activity may be carried out with guidance, or by allowing the student to follow their own method of solution. The approach should be chosen in sympathy with students’ skills and depth of understanding.

Activity

Three friends measured their heights:

• Jayne is one and a half metres tall.
• Chris is 1.6 metres tall.
• Amy is 1 m 58 cm tall.

Who is the tallest and who is the shortest?
Show how you know.

• The student is able to convert measurements to a common format in order to make a comparison.
