Reliable Length: Informal Units, Metres and Centimetres

Create a 6-slide Grade 6 Mathematics review deck for a 9-minute teacher-led synthesis after a group measuring investigation. Slide 1: estimate versus measure. Slide 2: accurate placement rules using clear visuals: align the start, units end to end, no gaps or overlaps, record number and unit. Slide 3: informal units including hand spans, paces, pencil lengths and counters, with a note that results may differ between people. Slide 4: metre sticks or one-metre lengths of string for longer objects. Slide 5: rulers and centimetres for shorter objects, showing the zero mark correctly. Slide 6: a worked example that estimates, measures, compares and orders three objects using the same unit, followed by a reminder that no metre-centimetre conversions are required. Include concise teacher prompts and age-appropriate examples; do not turn the deck into a worksheet or require written responses on slides.
