Mass and Measurement of Fruits

The video tutorial for grade four students focuses on solving a multi-step word problem involving a balance scale. The objective is to use addition and subtraction to find the mass of an apple, given the mass of a pineapple and other fruits. The lesson involves creating a tape diagram to model the problem, calculating the mass of a lemon by subtracting from the mass of an orange, and finally determining the apple's mass by subtracting the combined mass of the other fruits from the total mass.
