My sister does not know what a geoboard is. I was purging my homeschool supplies when I found I had not one, but 5 geoboards. 5! Why do I have 5? So I thought I would ask younger sis if she wanted one or two for her girls. And she looked at me blankly. We went through the same school system and yet I know what a geoboard is and she doesn't. How? Did they change math in-between teaching me and her? Probably. I even showed it to her and still Keep Reading...

## Midpoint Formula Activity {FREE Hands-On Lesson}

When I was a classroom teacher, the one thing I hated was trying to teach basic formulas. In most textbooks, this consists of stating the formula, telling students to memorize it, then showing them how to "plug in" all the necessary information. I don't like this approach because it doesn't give students any ownership over their learning. Plus, it usually means learning it for a day, then forgetting it. That's not the end result I'm going for. Keep Reading...

## Graphing Systems of Equations Activity {FREE}

I always loved finding a variety of ways to introduce, teach and explore systems of equations. It can seem like a daunting, overwhelming concept when students first hear it, but I think it's so fun and interesting! And solving systems certainly doesn't have to be as difficult or scary as kids think it is. What I love about this systems of equations activity, is that students get to explore graphing and solving systems in a non-threatening way, as Keep Reading...

## Measuring Angles Activity: Simple and Fun Puzzle Set {FREE}

Even though I taught (and LOVE) Algebra, there's one thing that I will always love about Geometry: it's hands-on and visual. I do realize Algebra can be hands-on and visual too, and I tried to teach it that way. But there is something much more obviously visual and tangible about Geometry. And I think this makes it fun! So if you're looking for a fun, engaging Geometry resource for 4th grade or 5th grade, you will love this measuring angles Keep Reading...

## Multiplying Large Numbers with a Table: Building Number Sense

I remember the first time that I was introduced to using tables for multiplying large numbers, division and more. Prior to that, my experience with tables included reading them, interpreting them, and graphing them. Pretty straight forward stuff that most Algebra students experience. Yet here I was, in a class for math teachers, looking at a table that was clearly written by a 2nd grader. I don't mean to say that the handwriting was so bad Keep Reading...

## How to Use Doodle Notes to Explore Absolute Value

As student attention spans get shorter and shorter, teaching for long-term retention becomes more challenging. Students groan at the thought of taking notes and listening to a lecture, and yet in math class, it is inevitable that there will be some direct instruction each time we introduce a new concept. Today I want to introduce you to a new method of note taking, and provide a free sample to explore absolute value with your Keep Reading...
