Classifying 2D Shapes
📋 What it is
Shapes are sorted by their sides and angles — triangles by side/angle type, quadrilaterals by their special properties.
🗣️ Coach says
Naming shapes isn't memorising — it's noticing. Count the sides, check if they're equal, check the angles. A square is just a rectangle with all sides equal, which is just a special parallelogram. Shapes are families.
🧠 Memory hook
A square IS a rectangle IS a parallelogram — going up the family tree, each keeps the rules and adds one more.
😂 Giggle
What did the triangle say to the circle?
"You're so pointless!"
😲 Whoa!
There are only 3 regular polygons that tile a floor with no gaps — the triangle, the square, and the hexagon. That's why bees build hexagons.
✅ Quick check: A four-sided shape with both pairs of opposite sides parallel — what family is it in?
Say your answer out loud first — then reveal.
A parallelogram (squares, rectangles and rhombuses all live inside it).
"Both pairs of opposite sides parallel" is the exact definition of a parallelogram.
