Description:

This activity allows students to learn about measuring by measuring.

To measure something students need to work through the following steps:

• Identify the attribute that is to be measured, (in this task it could be the length, perimeter, which is also a measurement of length, or area).
• Select the unit of measure (in this task start with informal units before moving to formal units of measure).
• Compare the object to the unit (this could be by covering, matching or some other way depending on the attribute being measured).
• Find the number of units (this can be done by counting, using instruments and eventually using formulas). Students need to name and number the unit for a measurement to have happened.

The use of informal units is an important step in order to develop understandings of what it looks like when measuring the attributes of length, perimeter and area.
