Yesterday we started a measurement unit in maths.
Our first lesson focused on mass. Mass is defined as the quantity of matter in an object. Mass is measured in grams and kilograms.
Our learning focus was:
- I am learning how to estimate and record using grams and kilograms.
Our success criteria was:
- I can make estimates about the mass of an object using grams and kilograms.
- I can make conversions between grams and kilograms.
Students were presented with a variety of supermarket items. They had to estimate the mass of each item and record their estimations. We also had lots of weights in the classroom so students could make informed estimations.
Today, we discovered the actual mass of each supermarket item. We compared our estimations and reflected on how close or distant our estimations were.
