Ms Cogan’s class went on a Math’s Trail on Thursday 29th September 2011. We were fortunate with the weather ..blue skies and brilliant
sunshine!
We found a 1D shape!
The line that separates the shadow of the storage container from the bright green grass
2. Then we searched the school grounds for 2D shapes
Square window Rectangular
windows
Circular centre in the flower
2D shapes have length and width
Can you see the 2D shape? Yes a semi-circle!
Will the rat be attracted to the circular entrance in the rat trap ?
2D means 2 dimensions
Squares have 4 equal sides and 4 right angles
A semi-circle!
2D shapes….
I see a pentagon ….Can you?
Another trapezium
Maths all around us
A semi-circleA trapezium is a quadrilateral
We found a perfect right angle!
Vertical line
Horizontal line
Parallel lines
And some final 2D shapes…….
Square
An isosceles triangle
Can you spot the trapezium ?
Next we looked for 3D shapes
The storage container is a cuboid
The water container is another cuboid
A 3D shape has length, width and depth.
Look at the cylinder
Two more cylinders!
Some more 3 D shapes!
Another cuboid
I found a cylinder
More 3D shapes………..
Can you find the cube…at the top of the chimney?
The Bath Road block of houses are a pentagonal prism
Length, width and depth = 3D
Can you spot the sphere …..on top of Bremore Castle?
Could the roof in the Mill Shopping Centre be a trapezoidal prism??
We found some angles
See the right angle
Right angle at the corner of the step
See the reflex angle of 270 degrees
When 2 lines meet they make an angle
straight angle
Straight angle
We learned that shape, lines and angles are all around us….
