Scale Read Intervals

Print: Ages 8–9 · 1–2 min · Core · Measurement intervals · Independent practice · Exact reading

Watch: Watch whether the learner counts the two spaces between 100 mL and 200 mL before entering a value. An answer near 33 shows that marks were counted instead of intervals; 50 shows the scale step and target were read correctly.

Misread: An answer of 100 mL or 200 mL suggests the learner copied a labelled mark instead of the water-line mark; 150 mL suggests they moved upward from 100 mL instead of one step down. A noun misread would treat the top label as cup capacity, while the scored action is to read the water level.

Curriculum: This task develops exact reading of a uniformly graduated capacity scale in millilitres. The scored skill is deriving one interval from labelled anchors, then applying scale direction to an unlabeled mark.
