One topic that I believe is too often rushed through, whether in pre-algebra or geometry, is the surface area of three dimensional objects. Because it is often seen as an "easy" topic where students are expected to simply "plug the numbers into the formula," it can be easy to say, "Here's the formula, GO." And while this may work for some students, especially students who have a strong foundation in geometry vocabulary and a strong understanding Keep Reading...

## Making Absolute Value Clear (With FREE Printables!)

One of the math concepts that I have seen students struggle with the most, and yet seems so simple at first glance, is absolute value. It often seems that the only thing students ever "get" from an absolute value lesson is this: absolute value = make it positive. That is NOT, however, the definition of absolute value, and therefore, becomes the cause of much confusion as students try to apply and use absolute value in more complicated problems.

## Hot Chocolate Math Investigation: Estimation and Measurement!

My kids love hot chocolate. It's such a special treat! When the weather is nice, they love to curl up in the yard at night and star gaze with a large cup of hot chocolate.

Whether they want a particular mug, or a certain color, it drives me insane to have them argue over which cup they get! However, Keep Reading...

## Equal or Not Equal? THAT is the Question!

In mathematics, an equation is a math sentence that shows two expressions that are equal. Understanding that these two expressions must stay equal is foundational as kids begin to learn Algebra. It is also important and useful as kids begin to write proofs or solve more difficult problems, because sometimes an expression is not written in a convenient way. But re-writing it in a way that is still equal (i.e. doesn't change the problem) is an Keep Reading...

I recently shared this number sense activity from Creative Family Fun. I love this simple activity because it gets kids thinking outside the box, and forming connections between number representations, place value and more.

This "Build a Turkey" number sense activity is great because it allows kids to be creative, and Keep Reading...

## Exploring Triangles with “The Greedy Triangle!”

The Greedy Triangle, by Marilyn Burns, is a great way to introduce shapes to young kids. It explores various shapes and gives copious examples of shapes in the world around us, and gave us a great starting place for exploring triangles! In addition, it provides an important character lesson: be content with who you are! Or as Dr. Seuss put it, Today you are you, that is truer than true. There is no one alive who is youer than you." *Please Keep Reading...
