Presentation transcript:

LO: To learn about properties of 2D shapes Sides Vertices curved -A line that is not straight straight - A line or edge which has no curves is straight.

Draw the curved edge in the air… draw the strait edge curved -A line that is not straight straight - A line or edge which has no curves is straight.

Vertices (corners) The point where 2 sides meet.

Rhombus (diamond) Parallelogram Trapezium Semicircle Ellipse (Oval) Pentagon Hexagon Octagon 1) Polygon – only strait sides 2) Quadrilaterals – 4 sides and 4 vertices (tell them 1 and 2, ask them to find one, and a counter example) New shapes – semicircle pent hex octa trapez paralella rhom ellipse Square & Rhombus/Diamond- (square on its side) equil length sides Rectangle & parallelogram – cerial packet to demonstrate how it changes Right angles – squ and rect

What shape can you see?

Main activity

What am I? I am flat. I have 4 straight sides of equal length. I have 4 right angles What am I? They can write their own, challenge partner. Time limit. Make sure they know to feed back after – random name generator.

LO: To learn about properties of 3D shapes Vertices Edges Faces Teacher input Vertices – like a corner but to make a sharp point. Faces – use a 3D shape, stick childrens faces on them Edge – next slide strait or curved Shapes in middle of table – (name generator) can you find a .... Show me- hold in air

face Flat and curved – talk about cylinder What shape are the faces – cube has square

edge Strait or curved Cylinder curved Sphere = none Cube = straight

edge face  vertex Is this right? Talk partners (10 seconds timer) Explain why not?

vertex  edge  face Were they right?

Polyhedron – flat faces and straight edges

What do you think this shape is called? Give picture clue Northern southern clue Reveal Talk about properties.

What shape am I? How do you know? sphere

Prisms – oposite faces are the same

pyramid

I have one curved face. I have no edges or vertices. What am I? Test eachother

What shapes can you see? Mouth – irregular octagon Eyes – square Head - cube Arm/leg/body – cuboid Minecraft cant make a perfect circle – square sunset -

Is it possible to make a circle on Minecraft?
