This Mathematics unit addresses the concept of measuring, comparing and ordering length using informal units.
It consists of 5 lessons of approximately 60 minutes duration.
The sequence of lessons and suggested time frames should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.
An assessment task for monitoring student understanding of the unit objectives is included and will require an additional lesson.
This unit plan includes the following resources:
- To measure and compare lengths of objects using informal units.
- To measure, compare and order height using informal units.
- To apply knowledge and understanding of length to a real-world context.
- To revise and consolidate the concept of length.
Preparing for Learning
Prior to commencing the unit, create a measurement display in your classroom. Display teaching resources in the classroom that will stimulate the students’ interest and assist in their learning. For examples of teaching resources to display in your classroom, browse the Length collection on the Teach Starter website.
Some of the resources which accompany this unit plan will need to be prepared prior to teaching. For this reason, it is advised that teachers browse through all lessons before commencing the unit.
Common Core Curriculum alignment
Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it wi...
Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
