Children build towers and make them equal.
Tap a step to mark it as done.
Place towers side by side for visual comparison. This makes the concept of equal immediate and concrete.
Use flat rows of objects on the ground instead of towers for children who find stacking difficult.
Do children count to check equality or rely on visual comparison? Can they adjust a tower to make it equal?
Stones, sticks cut to similar lengths, or any stackable objects work. If stacking is impractical, use flat rows of objects on the ground.
Children sometimes judge towers as equal by visual height without counting — a tower of large blocks may look the same height as a taller tower of small blocks but contain fewer. Always count as well as look.
