LI: to use formulas to find out the area of a shape, and to understand the anatomy of 2D and 3D shapes.
This week for maths we have been learning about measuring area of 2D and 3D shapes and formulas.
A 2D shape (2 dimensions) is a shape that only includes height and width, such as a circle, square, a triangle, etc. A 2D shape is completely flat as it has no depth which cannot be physically held. A 2D shape also has a name that connects with the amount of sides and/or corners the shape has.
A 3D shape (3 dimensions) is a shape that includes height, width, depth, such as a cube, cylinder, triangular prism, etc. 3D shapes are multidimensional which means they can physically be held. Some 3D shapes have a name that can connect to how many corners and/or vertices (corners) it has.
An example of formula is
the formula to find the area of a circle is A=pi x radius squared. (Which means 3.14 multiplied by the radius.
I enjoyed this activity because I got to learn things that I didint know before.
