It's here, friends! Pi Day 2015, where we get to celebrate a once in a century event!! Today on March 14, 2015 at 9:26:53 we experience the first 10 digits (3.141592653) of the number pi! Today has become especially meaningful to me, not just because I'm a math geek, or just because I love pi(e), (though both of those things are true!), but because of my little "pi baby." She was born weighing Pi! Ok, so she didn't weigh exactly pi (3.14 Keep Reading...
Exploring Volume: FREE Lesson!
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...
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...
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...
