## Using Nets to Understand 3-D Figures

#### Aligned To Common Core Standard:

**Grade 6 Geometry** - 6.G.A.4

How Are Nets Used to Understand 3-D Figures? Understanding the two categories of shapes is very important for kids. There are only two categories of shapes that we come across in life, and these are two-dimensional or 2D, and three-dimensional or 3D. Rectangles, circles, squares, triangles, trapezium, rhombus, etc. are all examples of 2D shapes. Cube, cuboids, spheres, cylinders, and pyramids are examples of 3D shapes. 2D shapes only have a length and width, while 3D shapes have a length, width, and depth, as well. It is easy for the kids to understand 3D shapes through two-dimensional nets. These are geometrical nets that are made of basic 2D shapes and can be folded into 3D shapes. Using a two-dimensional pattern to form a three-dimensional figure can clear the concepts of three-dimensional shapes that a lot of kids find it difficult to understand.

- Nets in Shapes Step-by-step
Lesson- I haven't seen nets in years. The core curriculum brought
them back.

- Guided Lesson - I cover
a lot of different shapes in this one.

- Guided Lesson Explanation
- I tried to use as many shapes as possible.

- Practice Worksheet - I
never thought of many of these shapes.

- Matching Worksheet - Another series of great shapes that we have to match. I like this one.

#### Homework Sheets

This was one of the coolest standards ever invented!

- Homework 1 - What shape will this net make?
- Homework 2 - What is the value of n? We know that a regular prism has 3 pairs of identical faces. Each face is a rectangle.
- Homework 3 - We can fold a net to make a 3-dimensional figure.

#### Practice Worksheets

These took me forever to design. I got the hang of it after a while though.

- Practice 1 - What is the volume of the shape?
- Practice 2 - We will add the 6 faces together to find the surface area.
- Practice 3 - A pass through the process for you.
