To continue with my study of 3-D shapes, I have created a lesson to begin exploring volume. Like surface area, this is something that is often rushed through, and students are told to just "plug it into the formula." But I have seen this lead to many unnecessary mistakes because students never actually understand where the formula comes from, and therefore they end up "plugging in" the wrong things. Understanding WHY the formula for prisms Keep Reading...

## Surface Area Practice Worksheets

Since I posted some lessons to help students learn and understand surface area last week, I thought I would add a couple of practice worksheets to go with it! These are simple and short, but I hope you find them helpful! The first has various prisms and cylinders, while the second covers pyramids and cones. I tried to use fairly simple examples so that they would be appropriate for middle school or high school, so if you are looking for more Keep Reading...

## Fun New Resource: Kidoku by Krazy Dad

How do you provide time for mathematical thinking, logic and problem solving outside of the textbook? How can we encourage students to think logically and problem solve, rather than simply memorizing facts? There are always ways to encourage higher order thinking in the math classroom, and I love it when I find resources that can encourage this kind of logical reasoning with my kindergartener! :) This week I have discovered a fun twist on Keep Reading...

## 3-D Shapes Worksheets! {FREE Printables!}

One Geometry topic that is introduced at a young age and then explored in more complex ways as kids get older is 3D shapes. Obviously, the first thing young mathematicians learn is to simply recognize the shapes, learn their names and discover them in the world around us. As kids get older, it's important to help them learn and understand polyhedron nets. Understanding what these shapes look like "flat" helps with spatial sense and reasoning and Keep Reading...

## The Importance of Math Vocabulary

Some of the most common errors I have seen teaching algebra occur because students simply cannot accurately "translate" words into mathematical models, or because they do not understand math "jargon" such as evaluate or simplify. I think this problem could easily be avoided, however, if one or two days were spent focusing on these skills. We cannot expect students to walk into class with a clear understanding of "math words" if they were never Keep Reading...

## Quadratic Equations Project (with FREE printables!)

One of the best ways to really learn something so that it sticks with you is to teach it to someone else. Giving students a project that gets them thinking through a mathematical process and allows them to express their creative side is always a win-win! The following example involves solving quadratic equations. A skill in Algebra that, while important, can very easily become boring and meaningless. And while I believe it is always helpful Keep Reading...
