Primary 7 have been looking at a range of 2D shapes. They used geoboards to see which ones they could make. Primary 7 , pick a 2D shape and describe it in as much detail as you can. How many different shapes can we think of?

Hexagon
Polygon
6 Sides
6 Angles
decagon
polygon
10 sides
10 angles
a triangle-has 3 sides,3 angles and it is equilateral sides
by abbie
octagon
An octagon has eight sides and eight angles.
lauren ~ a hexagon is a 6 sided shape it is a polygon and has 6 angles and edges.
Ellie~ a heptagon is a 7 sided shape it is a polygon with 7 angles. I remember that a heptagon has 7 sides by remembering that a heptathlon has 7 events.
I picked a hexagon.it has 6 sides and 6 internal angles which are sometimes obtuse
a pentagon is a polygon and it has 5 sides, 5 points and five edges. it looks like a house that’s how I remember it. Max picked a rhombus, he said that it has 4 sides, it is a quadrilateral. Courtney peat picked a square. it has 4 sides, 4 edges and 4 points.
Decagon
A decagon has 10 sides and 10 angles.
a rhombus is a quadrilateral shape which some people mistake for a diamond or kite but is much different from a kite because in a rhombus all the sides are same and in a kite two are different.
a square has 4 sides and it is a equilateral shape.
a kite is a shape that looks like a real kite
pentagon has 5 sides and 5 angles. Its also called a polygon.
My 2d shape is a hexagon. A hexagon has 6 edges and 6 angles.
Triangle-
A triangle is a 2d shape with 3 sides and 3 angles. The different triangles are Equilateral, Isosceles and a scalene. There are also right angled triangles, acute angled triangle and a obtuse angled triangle. An equilateral triangle has 3 equal sides, you would use this if you were making a house roof.
A Pentagon has 5 sides and 5 angles mostly obtuse
my choice is a square it a quadliratical shape it has 4 right angles and it 4 corners. A square is a special type of rectangle. All of the sides are the same length.
We have been learning about a decagon a decagon has 10 sides and you would usally call it a polygon.
Triangle –
Triangles come in lots of different shapes and sizes such as equilateral triangle which has 3 equal sides , isosceles triangle has two equal sides and a scalene triangle which has no equal sides.
Wow Primary 7 you really know your 2D shapes!
heptigon
decigon
dodecahedron
nonogon
paralleligram
rhombus
scalene triangle
isosceles triangle
equelateral triangle
we also learnt the difference between a polygon and a quadrilateral
polygon ~ more than 4 sided shap
quadrilateral ~ 4 sided shape
