Measurements
Hazelle was a grade 3 student. Her favorite subject was Mathematics. One day she came across the term ‘measurements’, and wanted to know what it meant. She asked her father who was a Mathematics teacher at her school. He took her to their kitchen, and pointed to some containers of water. He asked her how much water the vessel could hold. Hazelle said two litres. Her father told her that two litres was the volume of the vessel. Thus began Hazelle’s foray into the world of measurements.
