Explore, discuss and identify shapes that are and are not rectangles
Lesson details
Learning outcome
I can say if a shape is a rectangle or not and explain why.
Key learning points
- Rectangles have 4 straight sides.
- Rectangles have 4 vertices that are all the same. They are square corners.
- A square is a special type of rectangle with all sides the same length.
- An oblong is a rectangle with 4 sides that are not all equal.
Keywords
Rectangle - A 2D shape with 4 sides and 4 vertices that are all the same.
Square - A special type of rectangle with 4 equal sides.
Sides - The edges of a shape.
Vertices - The corners of a shape.
Straight - A line or surface with no curves.
Common misconception
Children may not see that a shape can have two different names e.g. a square is also a rectangle.
Use sorting hoops to sort rectangles and not rectangles. Then use a smaller hoop inside the 'rectangles' hoop to help identify the squares.
Teacher tip
The concept of right angles will be taught in KS2. At this stage, they are referred to as square corners to support children's understanding of rectangles. Children should explore the idea that the 4 vertices on a rectangle are always the same.
