Sort 3D objects and 2D shapes by one attribute, and identify the sorting rule
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
Sort by shape: circle, square, circle, square. How many groups?
📘 Worked solution
✓2 - circles and squares are two different shapes, so they form two groups.
And one from the hard end
You have 8 shapes: 3 triangles (2 red, 1 blue), 3 squares (1 red, 2 blue), 2 circles (both red). Sort by color first, giving group sizes - then explain how sorting by shape instead changes the groups, and give the new group sizes.
