Volume is basically the amount of liquid that is inside of a 3D shape. It's SUPER easy to calculate. The formula for Volume is: V = L x W x H Check out the videos below to further develop your full understanding of what volume is, how to calculate it, and what it is used for!
Area can be found from 2D shapes. However, SURFACE AREA is only found on 3D shapes! To calculate the surface area of 3D shapes, you first must figure out what shape every face is. Find the area of every shape, and then add it all up. That's all there is to it!
So far this school year, we have mostly focused on 2Dimensional (2D) shapes. Examples of 2D shapes would be rectangles, squares, triangles, parallelograms, trapezoids, pentagons, hexagons, octagons etc. A 2D shape is flat and has no depth at all. Only area and perimeter can be found on these shapes. 3Dimensional (3D) shapes are different from 2D shapes. While 2D shapes only have two dimensions such as length and width (or base and height), 3D shapes have three dimensions. The third dimension is called DEPTH. 3D shapes not only have length and width, but they also have depth. This is why 3D movies kinda pop out at you, rather than a regular 2D movie that does not pop out at ya! 3D shapes are often referred to as prisms or pyramids. Both a prism and a pyramid is more specifically classified by the shape of their base (or bottom). Pyramids can be triangular pyramids, square pyramids, rectangular pyramids, pentagonal pyramids, and so on. Prisms can be classified as triangular prisms, square prisms (or cubes), rectangular prisms, etc. The main difference between a pyramid and prism is that a pyramid has a pointy top and a prism is flat on BOTH the top and the bottom. When a 3D shape is unfolded and all of it's faces are laid out flat, we call that a NET. (Nets are often used to find surface area  but that's for another post!) 3D shapes also have faces, edges, and vertices. Check out the images and videos below to further develop your understanding of these shapes and their components.
We are about to embark on a brand new unit about geometry! We will begin this unit by studying 2D shapes and their area  or the space that they would cover if they were laid out flat like a blanket on the floor! Then, we will move on to 3D shapes, nets, surface area, and volume. (I'll put those topics in a serperate post!) Below is some helpful information to help you study and to further your understanding of finding area, what area is, and how area is used in real life. Thanks  Mrs. R
Percentages are super easy! The word PERCENT literally means "per hundred", or out of 100. If you are given the fraction 13/100, then this would convert into 13%. If you are given the fraction 28/100, then this would convert into 28%. Percent is something "out of onehundred". Check out the videos below about basic percentages.
Finding the percent of a number is a little more complicated, but it's still not hard! You use a proportion and the "bat and ball" method to solve. Check out the images and videos below to assist you if need be! :)
The following items should be in your Math folder to be graded as part of your S.T.E.M. portfolio:
1.) Ocean Floor Depth Chart 2.) Ocean Floor Map Grid 3.) Metric Conversions/Word Problems worksheet 4.) Summary/Reflection Ratios are a comparison of two different amounts using the word "to", a colon (:), or a fraction. Ratio fractions can be reduced just like a regular fraction. They are used to describe relationships. Rates measure amounts or the frequency of something such as prices, speed, value, etc. A unit rate measures something against the number one. Often, the word "per" is used when explaining a unit rate. Per means "one" or "each". In fact, the word "unit" also means "one" or "per" or "each". Check out the videos and images below for more information on ratios and rates. As always, thanks for stopping by! Mrs. R :)
Many of you have asked to see a few pics of our recent trip to NYC. So here you go! I hope you enjoy! :)

Hello there! I am delighted that you decided to stop by our math page! Please feel free to email me at any time if you have questions or concerns throughout the year. I hope that you will enjoy looking through the photographs of me, my husband, and our three 4legged "children"! Their names are Howie (brown), Henry (black), and Hank (black and white and goofy). Lets have a great year and go Rebels!!! :)
