Chapter Summary
Students should be able to accurately read and interpret various types of analogue weighing scales to determine the weight of an object, understanding the increments and starting points.
Students should be able to choose the most suitable unit (grams, kilograms, or milligrams) for measuring the weight of different common objects based on their typical size and weight.
Students must understand the relationship 1 kg = 1000 g and be able to convert weights between kilograms and grams, and also express combined units (e.g., 3 kg 500 g) solely in grams.
Students should be able to compare different weights expressed in various units (kg, g, or combined) and arrange them in ascending or descending order using comparison symbols (<, =, >).
Students must understand the relationship 1 g = 1000 mg and be able to convert weights between grams and milligrams, including expressing combined units (e.g., 4 g 100 mg) solely in milligrams.
Students should know the relationships between kilograms, quintals (100 kg), and tonnes (1000 kg or 10 quintals), and be able to perform simple conversions involving these units.
Students should be able to add two or more weights, including those expressed in combined units (kg and g), correctly carrying over or regrouping grams into kilograms when the sum exceeds 1000 g.
Students should be able to subtract weights, including those expressed in combined units (kg and g), correctly borrowing or regrouping from kilograms to grams when necessary.
Students should be able to multiply a given weight (in kg and g) by a whole number, either by multiplying each unit separately and then combining, or by converting to a single unit first.
Students should be able to divide a given weight (in kg and g) by a whole number, either by dividing each unit separately or by converting to a single unit first, to find weight per part.
Students must understand the relationship 1 l = 1000 ml and be able to convert capacities between litres and millilitres, including expressing combined units (e.g., 1 l 400 ml) solely in millilitres.
Students should be able to add and subtract capacities, including those expressed in combined units (litres and millilitres), applying correct carrying over and borrowing/regrouping principles.
