Spatial Sense – Measurement (Gr3)
Skills:
- Length – use appropriate units of length to estimate, measure, and compare the perimeters of polygons and construct polygons with a given perimeter (6:03)
- Length – use appropriate units of length to estimate, measure, and compare the perimeters of curved shapes and irregular shapes (4:27)
- Length – explain the relationships between millimetres, centimetres, metres, and kilometres as metric units of length, and use benchmarks for these units to estimate lengths (4:26)
- Length – use non-standard units appropriately to estimate, measure, and compare capacity, and explain the effect that overfilling or underfilling, and gaps between units, have on accuracy (2:16)
- Length – compare, estimate, and measure the mass of various objects, using a pan balance and non-standard units (1:23)
- Length – use various units of different sizes to measure the same attribute of a given item, and demonstrate that even though using different-sized units produces a different count, the size of the attribute remains the same (9:45)
- Time – use analog and digital clocks and timers to tell time in hours, minutes, and seconds (10:31)
- Area – compare the areas of two-dimensional shapes by matching, covering, or decomposing and recomposing the shapes, and demonstrate that different shapes can have the same area (1:18)
- Area Perimeter – use appropriate non-standard units to measure area (6:31)
- Area – the effect that gaps and overlaps have on accuracy (3:35)
- Area – use square centimetres (cm2) to estimate, measure, and compare the areas of various two-dimensional shapes, including those with curved sides (3:06)
- Area – use square metres (m2) to estimate, measure, and compare the areas of various two-dimensional shapes, including those with curved sides (1:43)
