Identifying Sides and Vertices in 2D Shapes for Year 2 Geometry Session

undefined
 
YEAR 2 – GEOMETRY
 
Session 1 – identifying sides and vertices in 2D
shapes.
Recap
What are the names of these 2D shapes?
 
Circle
 
Triangle
 
Square
 
Rectangle
How many sides does a rectangle have?
 
To find this out we need to know 2 things.
 
Side
 – this joins together two 
vertices.
 
Vertex
 – you many have called this a corner. A 
vertex
 is where two sides met at a point.
When we are talking about more than 1 vertex we call these 
vertices
.
 
Sides -
 
a rectangle has 4 sides.
 
Vertices -
 
a rectangle has 4 vertices.
How many sides does a square have?
 
Sides -
 
A square has 4 sides.
 
Vertices -
-
 
A square has 4 vertices.
 
What is the same about a square and a rectangle?
 
They have the same number of sides and the same number of vertices.
 
What is different about a square and a rectangle?
 
In a square all the sides are the same length. In a rectangle a pair of sides are longer than the
other pair of sides.
How many sides does a circle have?
 
Sides -
 
A circle has one side that goes all the way around.
 
Vertices -
 
A circle as no vertices as it doesn’t have 2 sides that meet at a point.
What is this shape? How many sides does it have? How many
vertices?
 
Sides -
 
There are 5 sides.
 
Vertices -
 
There are 5 vertices.
This shape is called a
pentagon.
What is this shape? How many sides does it have? How many
vertices?
 
Sides -
 
There are 6 sides.
 
Vertices -
 
There are 6 vertices.
This shape is called a
hexagon.
What is this shape? How many sides does it have? How many
vertices?
 
Sides -
 
There are 7 sides.
 
Vertices -
This shape is called a
heptagon.
 
There are 7 vertices.
What is this shape? How many sides does it have? How many
vertices?
 
Sides -
 
There are 8 sides.
 
Vertices -
 
There are 8 vertices.
This shape is called an
octogan.
 
All these shapes are called 
polygons
 
A polygon is a 2D shape with straight sides.
 
A circle is not a polygon as it doesn’t have straight sides.

  1. YEAR 2 GEOMETRY Session 1 identifying sides and vertices in 2D shapes.

  2. Recap What are the names of these 2D shapes? Square Triangle Circle Rectangle

  3. How many sides does a rectangle have? To find this out we need to know 2 things. Side this joins together two vertices. Vertex you many have called this a corner. A vertex is where two sides met at a point. When we are talking about more than 1 vertex we call these vertices. Sides - a rectangle has 4 sides. Vertices - a rectangle has 4 vertices.

  4. How many sides does a square have? Sides - A square has 4 sides. Vertices - - A square has 4 vertices. What is the same about a square and a rectangle? They have the same number of sides and the same number of vertices. What is different about a square and a rectangle? In a square all the sides are the same length. In a rectangle a pair of sides are longer than the other pair of sides.

  5. How many sides does a circle have? Sides - A circle has one side that goes all the way around. Vertices - A circle as no vertices as it doesn t have 2 sides that meet at a point.

  6. What is this shape? How many sides does it have? How many vertices? This shape is called a pentagon. Sides - There are 5 sides. Vertices - There are 5 vertices.

  7. What is this shape? How many sides does it have? How many vertices? This shape is called a hexagon. Sides - There are 6 sides. Vertices - There are 6 vertices.

  8. What is this shape? How many sides does it have? How many vertices? This shape is called a heptagon. Sides - There are 7 sides. Vertices - There are 7 vertices.

  9. What is this shape? How many sides does it have? How many vertices? This shape is called an octogan. Sides - There are 8 sides. Vertices - There are 8 vertices.

  10. All these shapes are called polygons A polygon is a 2D shape with straight sides. A circle is not a polygon as it doesn t have straight sides.
