The sum is the same, no matter how you got there; so how'd you get there?

Yet another example of adults saying "But there's a better way..."

No one would argue that you, adult, can add probably faster than an elementary school student.

We are in the process of building UP TO that speed and accuracy. By encouraging your child to imagine the groupings, you are building their imagination (draw whatever you'd like!), their math skills (count up, make 10s), and their mental flexibility ALL IN 1 PROBLEM!

Check out my NEW addition video for a little more about how this problem is VERY similar to what many adults already do!

Making sense of a problem IRL isn't about having an algorithm to write out your work. Instead it's about applying what you know to a REAL situation.

This is what most adults
think of when they see
an addition problem:

But this is what many
adults actually do when
adding mentally.

Homework = Tears? What's the upstream problem?

Tell me if you've heard this one before... Parent and child at the table working on child's homework. Child becomes frustrated and begins to cry Parent becomes equally (or more) frustrated by the tears/the assignment/both. Sound familiar? It's pretty common, but let's ask a new question - what's the upstream problem? Not familiar with the idea of "upstream problems"? It was new to me until very recently - but the best description I've heard is this: There's a town in which every evening a child washes up on the banks of the local river. Every day the fire department rescues the child and is lauded as heroes. One day a new fire chief takes ov...

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!

Cognitive Dissonance - adapting to new information

The last year or so has shown us all a lot about the world we live in and the people we share it with. It's interesting to see how tightly individuals may cling to ideas or beliefs that have later been shown to be inaccurate and have been updated. That's the scientific method in a nutshell - make a prediction, test it, learn something, adjust. Math works the same way, but I'm seeing that the "adjust" step is becoming harder and harder for students to make. I had an experience in my Algebra class that sort of outlined the apparent push to reject what is proven in favor of what makes us comfortable (more about that in the video) and it got me thinking. This whole math education thing (or compulsory schooling in general) isn't about cramming kids' heads full of information. It's more about opening them up to conflicting ideas (cognitive dissonance for all you psychology/education fans out there) and giving them the tools to determine true from false, fac...
