Guess what? After many, many months of working on mapping out memory work and designing Cycle Memory Books, we finally have some new content to release. Geometry songs are now posted on our__ Math songs page__! (You must be an All-Access subscriber to play the songs.) Many of these songs have been set to familiar tunes, so they should be easy to learn. We also finished our "__Skip Counting__" series with a song for the cubed numbers through 1000.

I'm especially excited about our songs that correspond with specific shapes. Not only do they describe the properties of each shape, but they also include how to find the area/perimeter of each shape within the same song. Some of the songs include additional information as well, such as how triangles are classified or the value of pi. As with all of our songs, I have posted lyric videos with visuals to accompany each song. However, the songs can also be streamed directly through the __Music Player__. I've posted our "All About Squares" song as a sample at the bottome of this post

Below is an overview of the content in each new song. Happy Fall, Y'all!

**Volume** is the amount of space occupied by a three-dimensional object such as a sphere, cube, cylinder, pyramid, and cone. (Cycle 1 & 3, Week M)

**Area **is the amount of space taken up by a two-dimensional (flat) surface. **Perimeter **is the length of the boundary around a two-dimensional shape. (Cycle 1 & 3, Week N)

**Properties of a Square**: a quadrilateral with opposite sides parallel, four right angles (90°), four equal sides, and four vertices. The **area of a square** is length of its side squared (s²). To find the **perimeter**, add all the sides or multiply 4 times the length of one side. (Cycle 1 & 3, Weeks O-P)

**Properties of a Rectangle**: a quadrilateral with opposite sides parallel, opposite sides are equal, and four right (90°) angles. The **area of a rectangle** is length times width. To find the **perimeter **of a rectangle, "add all the sides." (Cycle 1 & 3, Weeks Q & R)

**Properties of a Triangle**. A triangle has three sides, three angles, and three vertices. The sum of all internal angles is always equal to 180°. **Triangles can be classified by their angles or their sides.** Equilateral= 3 equal sides; Isosceles=2 equal sides; Scalene = no equal sides; Acute= all angles are less than 90°; Obtuse= one angle is greater than 90°; Right = one angle is equal to 90°. The** area of a triangle** is half of the base times the height. To find the **perimeter **of a triangle, "add all sides." (Cycle 1 & 3, Week S-U)

**All about Circles**. The **radius** of a circle is the distance from the center to any edge. **Diameter **is the distance across a circle through the center point. Diameter is always equal to 2 times the radius (D=2r). **Circumference **of a circle is the distance around the edge.

Circumference of a circle is 2πr (2 x pi x radius). The **area of a circle **is πr2 (pi x the radius squared). The **value of pi **(π) is 3.14159. (Cycle 1 & 3, Weeks V-X)

**Cubed numbers through 1000. **

1, 8, 27, 64, 125, 216, 343, 512, 729, 1000 (Cycle 1-4, Week K)

Sample "All About Squares" available on YouTube or with the sample songs on our site!
