Standard units are used to describe, measure, and compare attributes of objects’ shapes.
measurement, using standard units (linear, mass, and capacity)
linear measurements, using standard units (e.g., centimetre, metre, kilometre)
capacity measurements, using standard units (e.g., millilitre, litre)
Introduce concepts of perimeter, area, and circumference (the distance around); use of formula and pi to calculate not intended — the focus is on the concepts.
area measurement, using square units (standard and non-standard)
mass measurements, using standard units (e.g., gram, kilogram)
estimation of measurements, using standard referents (e.g., If this cup holds 100 millilitres, about how much does this jug hold?)
understanding concepts of time (e.g., second, minute, hour, day, week, month, year)
understanding the relationships between units of time
construction of 3D objects
identifying 3D objects according to the 2D shapes of the faces and the number of edges and vertices (e.g., construction of nets, skeletons)
describing the attributes of 3D objects (e.g., faces, edges, vertices)
identifying 3D objects by their mathematical terms (e.g., sphere, cube, prism, cone, cylinder)
comparing 3D objects (e.g., How are rectangular prisms and cubes the same or different?)
understanding the preservation of shape (e.g., the orientation of a shape will not change its properties)
