Planning and Activities
Day 1 Teaching
Show children a chair and a cube. How many cubes high do they think the chair will be? Estimate then measure the chair height in cubes (10s and 1s). Repeat, to measure the height of other objects in cubes.
-- Measure classroom objects with cubes.
-- Estimate and measure using a (30cm) ruler.
Day 2 Teaching
Use a 20-bead string to measure a child’s hand span in beads. Measure other hand spans, estimating the length first. Then work in pairs to estimate and measure each other’s foot lengths in beads.
-- Make a play dough worm family within a certain length.
-- Find objects longer/shorter than 20 beads.
Day 3 Teaching
Take children to the hall. Pass metre sticks around. Ask children to feel their length. These are one metre long. Explain that these are a standard unit. Measure the length of the hall in metres by laying sticks along one side. Repeat to measure its width.
Use the ‘Make a stick’ in-depth problem-solving investigation below as today’s group activity.
Or, use this activity:
-- Find objects longer/shorter than a metre stick.
