Splitting, Joining, and Moving Shapes
Year 2 Mathematics Exploring how shapes can change and transform
What Are Shapes?
Shapes are all around us They have special features like sides and corners We can name shapes by counting their features
Shape Hunt Around Us
Look around the classroom Find 3 different shapes Tell a friend what you found
Splitting Shapes
We can cut shapes into smaller pieces Each piece is still a shape Splitting creates new shapes from one shape
Let's Split Shapes!
Draw a circle on your paper Use a ruler to split it in half What new shapes did you make?
Think and Share
If you split a square in half, what shapes can you make? Can you think of different ways to split it?
Joining Shapes Together
Two or more shapes can be joined Joining creates bigger, new shapes The new shape might look completely different
Shape Building Challenge
Use 2 triangles to make a new shape Use 2 squares to make a rectangle What other combinations can you try?
Splitting vs Joining
{"left":"Splitting makes MORE shapes from ONE shape\nJoining makes ONE shape from MORE shapes","right":"Both create NEW shapes\nBoth are fun ways to explore geometry"}
Moving Shapes - Sliding
Shapes can slide to new positions The shape stays exactly the same Only the position changes
Moving Shapes - Flipping
Shapes can flip like turning a page The shape looks like a mirror image We call this reflection
Moving Shapes - Rotating
Shapes can turn around like a spinning wheel The shape stays the same size It just faces a different direction
