Keep, Borrow, Change...Right?

Subtraction - Take Aways - Whatever you call it this is the first "big" hurdle for many students in a long race of mathematics.

It turns out that this first hurdle is often the first time parents seem to get beyond frustrated with the MANY ways students are presented with solving a subtraction problem. All of the skills you'll see in this video are essentially shortcuts that many discover on their own through mental math and practice. By presenting them to students at a young age they become more and more comfortable with numbers and their reasoning and number sense improves overall.

Enjoy!

The Power of Yet (and I Don't Know)

This one's for all the parents facing the "why...?" and "how...?" and "why not...?" and "do I have to...?" questions. And for the teachers (and parents) who are uncomfortable with admitting they aren't the omniscient geniuses we'd like our kids (and students) to believe we are. There is a LOT of power in the word YET. And even more power (in my opinion) in admitting you don't know. Students of all ages need to know that they don't have to know everything - and the people in their lives don't know everything either. Try it out. It's OK to not get it, yet. It's OK to not know. Let's find out together.

It's not new, it's meta

Metacognition: a buzz word that educators like to throw around Metacognition: thinking about thinking Yes, that's a real thing teachers are asked to do on a regular basis. We are expected to anticipate errors our students might make before they make them. We are constantly on the look out for students who have a different approach than their peers to a problem. And now we're seeing these "metacognition" problems showing up on standardized tests for all ages. The practice of explaining your thinking can be a tough one to wrap our heads around as adults. It feels easier to say "It just IS the answer." But we want to dig deeper into HOW or WHY you arrived at your answer because It's Not New, It's Meta

There's HOW MANY ways to add 2 numbers?

To answer the title question - a LOT! We take for granted that most of us adults can add quickly because we "know our math facts". For many of us that may be true, but I would bet that the vast majority of adults out there do quite a few of the addition strategies your children are taught in elementary school without even knowing it! This video addresses some of the addition strategies that I've seen frustrating parents. Addition Video As always, let me know if there's a topic you'd like to see Demystified!
