Purpose
The purpose of this activity is to engage students in using standard measuring tools in a non-standard manner.
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.
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.
- addition and subtraction basic facts
- metric measures of length
- converting between mm and cm
- using a ruler (cm and mm)
- working with numbers to one decimal place
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.
