Measurement of Area

In grade 1 and 2, children are introduced to the concept of area. The learning goal of the activities I prepare for them is for them to measure the surfaces of objects using non-standard units of measure and in class I usually offer them math manipulatives such as pattern blocks and interlocking cubes. Parents, however, do not have these resources at home so I had to be a little creative with my task when planning a lesson for my students to do at home.

The curriculum does not state precisely what unit of measure children are to use, so I instructed the children to use a household object. I showed them an example that I did in which I used forks:

In addition, I gave my students the sentence starter to use when they wrote down their response. Translated, the sentence states: I measured a(name of object). The surface of the (name of object) is (number used) (name of household object used).

I liked seeing my students’ innovative choices of units.

Food played a role in some responses:

As did the games they play with:

Other responses included the use of business cards, Lego, and toilet paper rolls (I loved this one!).

I am sure these children will not forget what it is to measure the surface area of an object – even when thy have to use standardised units of measure in the higher grades.

What would you use to measure the surface of an area?
