Mathematics 6: Geometry & Measurement

Let's explore the difference between similar and congruent figures (similarity vs. congruence) in this conceptual mini-lesson.

This video explains what rotational symmetry is and how to find the order of rotational symmetry of a shape. Practice questions and answers are at the end of the video.

In this video, you'll learn that symmetry has a lot to do with cutting shapes in half. With some shapes you can only have one line of symmetry but other shapes have more. Why?

Symmetry doesn't just apply to simple geometric shapes. We can create a line of symmetry for many complicated objects!

On this lesson on lines of symmetry, you will learn about reflection symmetry, vertical line symmetry, horizontal line symmetry, and examples of line symmetry.

All shapes have a two-dimensional property called area. Learn how to figure out what the area of a shape is in this video!

A parallelogram is like a rectangle that's been nudged over. You know how to find the area of a rectangle... length x width. It's not that different from finding the area of a parallelogram.

The area of a parallelogram is base x height. In this video we are given the area of the parallelogram and the height. What will be the base? We will take the area and divide it by the height. And this will give us the base.

When it comes to area, a parallelogram is a lot like a rectangle -- just as alike as Fred and George Weasley. Watch this video to confirm it!

A great review for students working on finding the area of geometric objects

Finding height of a parallelogram isn't as hard as potions class, but you do need to pay attention if you want to get it right.

Whether you're just starting out, or need a quick refresher, this is the video for you if you're looking for how to find the area of a composite rectangle.

When we determine the area of a composite shape made of rectangles, we separate the shapes first. Guess what we do with composite shapes made up of one or more triangles?

In this video, students will learn how to calculate the area of a parallelogram and a triangle.

If you want to master Arithmancy like Hermione, you'll need to learn about triangles, their angles, and their area.

In this lesson, you will learn how to find the side length of a square given its area by using what you already know about squares to guess and check.

If you want to find the volume of a rectangular prism using unit cubes to visualize the problem

Today, we'll learn that volume is a characteristic of all 3D objects. We'll learn how to determine the volume or space in 3 dimensions that an object takes up.

In this video, you'll learn a simple formula for calculating the volume of a rectangular prism.

In this video, students will see why four sided objects will tessellate.

This video explains WHY there are only three regular polygons that tessellate on their own. It demonstrates visually and mathematically that only triangles, squares, and hexagons will be the only regular polygons to tessellate.

What is a tessellation in Math and how to calculate if a shape will tessellate to form a pattern.

This site has easy to follow instructions for making simple to complex geometric shapes.

Pentominoies are shapes made by joining five squares together. There are 12 of them in total, and they can be used for various geometry and interdisciplinary art activities in math.

There are countless different shapes that can be created using the seven Tangram tiles. What can you and your students come up with?
