We've decomposed numbers before to make them easier to work with, like how we decompose the number 12 into 10 + 2. That same concept is really helpful when working with angles, too!
Now that you know what angles are, you're ready to start measuring them! The tool we use is called a "protractor", and in this lesson we'll review how to use it, and how to read the numbers on a protractor to measure any angle.
Do you need to learn about the different types of angles in 4th grade? This educational kids math video shows upper elementary math students how to classify different angles!
This activity uses coloured yarn to make shapes. Choose the yarn and then stretch it across the pegs. Students can make line segments or shapes and then work out the perimeter, area, angles, and more.
Polygons are formed by several parts: sides, vertices, angles and diagonals. Also, they can be regular (all sides and angles equal) or irregular (not all sides or angles equal).
We have been rocking it with rectangles, squares and triangles! But what makes a square different from a rhombus or a rectangle or even a trapezoid? Let’s dive into the world of quadrilaterals!
Understanding different kinds of shapes can help you better understand patterns and how to create and design objects. Let's take a peek at this video to learn what makes a shape a polygon!
From spirals to spots to fractals, nature is full of interesting patterns. Many of these patterns even resemble geometric shapes. One of the most common? Hexagons. Why do we see this six-sided shape occur so many times in nature?
