How can 2D shapes be classified?

2D shapes can be classified as closed shapes and open shapes. A closed shape means its sides are connected from end to end with no break in the connection. Comparatively, an open shape means at least one endpoint of one side is not connected to the rest.

What is a 2D shape with 5 sides?

pentagon
A pentagon is a five-sided polygon (2d Shape), and it can be regular or irregular.

What are some 2D figures?

Some common 2D shapes are square, rectangle, triangle, circle, and hexagon. In comparison to these, a 3D (three-dimensional) shape has three dimensions – length, width, and height. For example, a dice is three-dimensional because it consists of a length, a width, and a height.

What are the standards for classifying two dimensional figures?

The standards that require students to classify two dimensional figures based on their properties and create a hierarchy of shapes. Let’s break down this standard so we understand the why behind this concept.

How to create a hierarchy of two dimensional figures?

The standard 5.G.4 takes this a step further and has students create a hierarchy of two dimensional figures based on their properties. This just means that students are using a visual representation to thoughtfully organize the ideas and groupings students discussed in the previous standard. PIN THIS POST!

What are the geometry standards for 5th grade?

If you’re anything like I was when I first started teaching 5th grade math, then you probably aren’t too excited about those dreaded geometry standards. You know which ones I’m talking about… The standards that require students to classify two dimensional figures based on their properties and create a hierarchy of shapes.

Can a student create a hierarchy of figures?

It will be impossible for students to create a hierarchy of figures if they are unable to identify their properties. The purpose of this activity is to break students of the “it looks like this, so it must be this shape” mindset by taking away their ability to actually see the shape.
