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 Introduce and Teach Unit Rate: Practical Tips
So, your child is stuck on their homework. They have to find "unit rate." And you're looking at their homework paper and thinking, "What is unit rate?" Or at least, that's what my husband said when he asked what I was writing about. "Unit rate, huh. What's that?" I was a little surprised that my math savvy husband didn't know about this crucial math skill he probably uses nearly every day. Once I told him what it was he said, "Oh. I use Keep Reading...
Simple and Fun Division BINGO Game: Answers as Fractions
If I were to hand my six-year-old 2 cookies and ask him to share it with each one of his siblings, he would know what to do. He would simply cut each cookie in half. Almost instinctively, he can see that he gets half, his brother gets half, and his twin siblings will each get half. In situations like that, dividing makes sense. Place a problem like 2 ÷ 4 in front of him, however, and confused looks are inevitable. So today I'm going to Keep Reading...
How to Teach Subtraction with Regrouping: Simple Strategy
One of the most common struggles that I hear from parents and teachers is teaching subtraction with regrouping (or borrowing).

Now, I don't share this because I have all the answers, or because this is the only method to use, or because I think it will work for Keep Reading...

In fact, I created one just for Math Geek Mama Readers. Help kids learn and understand math in a real world context with this add and subtract decimals Keep Reading...
Multiplying Mixed Numbers Activity {FREE Puzzles}
To be completely honest, I used to dread it. Teaching multiplying mixed numbers by mixed numbers could become messy business. The steps were numerous, and one little mistake guarantees that the problem will be wrong. That all changed when I learned how to model multiplying mixed number by mixed numbers. This abstract concept now made sense to me, and I could help my children visualize it too. This once tedious process, became fun as we drew out Keep Reading...
Subtracting Mixed Numbers Printable Board Game {FREE}
Ask a second or third-grade teacher what their students are struggling with and you might hear subtracting with regrouping. Ask an upper elementary teacher the same question, and you may not hear a different answer. Their answer may just involve fractions. Regrouping is difficult and when you add fractions, it can seem like an insurmountable challenge. Just like any arduous math concept, interactive notebooks, manipulatives, and games can make Keep Reading...
How to Build a Solid Mathematics Foundation
There is one vital concept all math students must know in order to be successful. Does your student have it mastered? Maybe your student struggles with multi-digit addition or multiplication. Maybe it's division that's got them hung up. Or perhaps, it's subtraction with (gasp!) regrouping. In all likelihood all of these struggles can be boiled down to one issue: Place value. *Please Note: Some of the links in this post are affiliate Keep Reading...
Simple Strategy to Teach Multi-Digit Multiplication
Your student is sitting at the dining room table. He’s supposed to be doing his math assignment. Instead, he’s doodling his hate for the subject in the margins.

You start thinking, maybe it’s not that important. Maybe I should just get out the Keep Reading...
3 Types of Math Errors and How to Prevent Them
When you are learning a new skill, do you do it perfectly the very first time? Do you know all the answers before you even begin? Of course not! The same is true of math. Learning math requires practice, and making mistakes is part of the process. But as I've shared before, making mistakes in math is a good thing, and can help kids learn and understand more deeply. Today I want to dive a little deeper, because all mistakes are not equal. There Keep Reading...
