4 ideas in Class 1 Mathematics, explained in plain words, with games and quizzes to practise.
Tall and Short
Part of: Comparing size and distance
Tall and short compare heights. The tallest person is taller than everyone else, and the shortest is shorter than everyone else. A child can be taller than mother but shorter than father.
Why it matters. Comparing heights is children's first measurement. It teaches them to observe, order and describe the world.
Try it in two minutes
- Stand family members back to back and ask: who is taller?
- Order three people from shortest to tallest.
- Ask: who is taller than mother but shorter than father?
Try at home. Ask your child to find the tallest and shortest person at home by standing together.
Long, Thick and Near
Part of: Comparing size and distance
Long and short compare length, thick and thin compare fatness, and near and far compare distance. The longest rope, the thickest book and the nearest shop each win their own contest.
Why it matters. Each thing needs its own comparing word. Children who mix them up say a rope is thick when they mean long.
Try it in two minutes
- Lay two pencils side by side. Ask: which is longer?
- Hold a thread and a rope. Ask: which is thicker?
- Point at home and school. Ask: which place is nearer?
Try at home. Ask your child to bring the longest spoon and the thickest book from the kitchen shelf.
Measuring with Body Units
Part of: Comparing size and distance
A handspan is the spread from thumb tip to little finger tip. Fingers measure tiny things like seeds, and footspans measure floors and rooms.
Why it matters. Body units let children measure anywhere without a ruler. They also show why fixed rulers were invented: hand sizes differ.
Try it in two minutes
- Spread your hand and measure a book in handspans.
- Measure a seed with finger widths.
- Walk heel to toe across the room counting footspans.
Try at home. Measure your table in handspans and a key in finger widths, then compare notes.
Heavy, Light and Holds More
Part of: Comparing size and distance
Heavy and light compare weight: a full bag beats an empty one. Holds more compares capacity: a bottle that fills 6 cups beats one that fills 4. Small jobs need small water, like a mug for brushing.
Why it matters. Weight and capacity guide daily choices: what to carry and how much water each job needs. It also builds care against wasting water.
Try it in two minutes
- Lift a full bag and an empty bag. Ask: which is heavier?
- Fill two bottles cup by cup and count the cups.
- Ask: brushing needs a mug or a bucket?
Try at home. Compare a full bottle and an empty bottle by lifting, then count cups to see which holds more.
