Visualizing and Naming Polygons
A really useful resource contains 116 slides covering basic geometric concepts related to 2-D or plane shapes. Shape properties, translations, reflections, congruence, symmetry, and grid work are all laid out in a comprehensive and...
Curated OER
The Shape Show
Define plane shapes by their properties, then use this game to reinforce those skills. Learners use given properties as clues to determine each shape. They work to name ten different shapes, six of which are polygons.

Classifying Polygons
A straight edge, a right angle, a number of vertices; sounds like it's time to classify polygons. That's right you and your class will learn all about the properties of polygons and how to classify them with this easy to follow...
Curated OER
Year 5 Unit D1
This presentation is intended to accompany an entire unit and covers a wide variety of concepts. Counting on, counting back, symmetry, properties of 2-D shapes, completing symmetrical patterns, and measuring angles are all covered.
Curated OER
Shapes: Art or Geometry
Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

Color the Right Shapes
I remember doing this activity when I was little. Learners color each shape the color indicated at the top of the page. Squares are blue, cubes are red, circles are green and so on. There are 30 shapes to identify and color.

Making Two-Dimensional Shapes- Matching Worksheet
Now that your learners recognize two-dimensional shapes, can they find what each half of those shapes would look like? There are seven shapes on this worksheet, bisected by a dotted line. Scholars examine these shapes and match them to a...
Curated OER
Some Shapes
Introduce the names and properties of basic 2-D shapes. Images and defining features of the circle, rectangle, triangle, and square are shown. Each image is colorful and includes a happy, smiling face, perfect for younger learners.

2-D Shapes: properties Review
Play to review the various properties that help us identify 2-D shapes. Five different shapes are presented first by their properties only, these clues are then used to identify each shape. This is a great warm up activity, especially...

Area of Regular Quadrilaterals
Can your class calculate the area of a regular quadrilateral? They can now, with this handy presentation which provides an explanation, the formula, and examples of finding the area of a regular 2-D shape.

2-D Shapes Show
As the green squares are removed, a little piece of the puzzle is revealed. What is it? A square, a triangle, a cow? Have your class guess their way to identifying five different plane shapes.
Curated OER
2-D Shape Recognition
How many of 2-D or plane shapes can your class identify? Can they get them all? Little learners view and review the names of nine different shapes, such as rectangle, square, triangle, and circle, to name a few.

Revise Identifying 2-D Shapes pg 1
The identification of 2-D shapes is the focus of this geometry activity. Students compare figures and match them to their shape name. Students identify eight different shapes.

What Shape Is That Object?
Before begining this instructional activity you will need to clarify if learners are to write the 2-D, 3-D, or both version of each shape shown. They are to write the name of the shape they see. Some may be cones, spheres, or pyramids...
