### How It Works

**Welcome** to Math That Makes Sense: How to Teach Elementary Arithmetic. I originally taught this course live at the Well-Trained Mind Academy to a group of about 15 parents, in the fall of 2016. It was a joy to teach them and see their commitment to giving their kids a great math education! Now, I’m thrilled to be able to provide all the course videos for free, right here at my website.

If you’d like to **take the whole course**, you’re welcome to do so! There are eight 90-minute videos that cover all of that cover all of elementary arithmetic, from preschool number sense to multi-digit multiplication and division. Each video is on its own page, so just click the title to go right to that video. Start at the beginning and watch the videos in order. Bear in mind that the original students used a textbook (and even completed homework!), but you don’t need the textbook to be able to learn from the course. (If you’d like to buy the textbook as a reference, you can find it at Amazon.)

Or, if you’re looking for **help on a specific topic**, you can just go straight to the matching video. You’ll see the outline of the whole course below. Just search for the topic you’d like to learn more about and go to that video. Once you’re there, you’ll find an outline with time stamps so you can go right to the question you’re interested in.

Please feel free to add your comments and questions to the page for each video. I’d love to hear what you find most helpful in the classes and how you put them into practice with your own kids.

Happy Math!

I just stumbled across your blog as it was linked from Pam Barnhill. So happy you exist! Can’t wait to receive your emails!

Thanks, Renee! I hope you find them helpful! Definitely let me know if there’s anything specific you’re wondering about–I love to write articles about homeschool moms’ real-life math challenges.

I stumbled here also… after Googling, “Does Singapore math have tests after each chapter”. I am homeschooling my 7 year old who adores math (while I secretly hate it and am worried I’ll mess up trying to teach him a subject I never liked) With him; and likely most kids, there is an important teaching point between, “Too easy, I’m bored…… and…….too hard, I give up” . Additionally, and very unlike myself, this kid is so adept at math that I wonder if I’m allowing him to move ahead too quickly.

And so – I like Singapore math and will certainly stick with it, but I do wish they had tests or accumulative review pages after 3 chapters or so. If nothing else, it would boost my confidence that I’m teaching well and he is retaining the material. I can always make my own up though!

As it is; I use Xtra Math online to make sure he can do a lot of quick math facts…. it’s like Kumon but free and on the couch!

Our family enjoys your “Facts that stick” books, thank you so much! Games are fun, worksheets are short and to the point and is very practical. I am looking forward to watch these videos, too!

Glad you and your kids have enjoyed Facts That Stick, Sally! Happy Math!

Thank you so much for these videos! I found and watched this course on the WTMA but my kids were kindergarten age. I so needed this refresher.

My oldest is now learning the addition and subtraction algorithms and I know multiplication is coming! I expect I will be back for a refresher again when we get deeper into multiplication and division algorithms. Extremely informative and helpful!

I’m so glad you’ve found them helpful, and that you’re now able to watch them as a refresher. Thanks for taking the time to let me know, and happy math!
