Lesson notes

Learning Objectives

Indicator: B2.3.3.1.2 - Develop an understanding of measuring as a process of comparing three or more items

By the end of the lesson, learners can:

Compare three or more objects by length, height, mass or size using the words smaller, smallest, longer, longest, bigger, biggest, heavier and heaviest.
Arrange three or more objects in order from smallest to largest (or largest to smallest) after direct comparison.
Use indirect comparison to order objects that cannot be placed side by side, using a non-standard tool such as a stick, piece of string or their own handspan.
Justify their ordering of objects by explaining the steps they took to compare them.
Work in small groups to collect objects from the environment and present their ordered set to the class with a clear explanation.
