Maria's Math News, November 2016

As we are all awaiting what happens with the historic election, I still have for you some math resources, hopefully something for everyone. smile

In this edition:
  1. Math Mammoth news
  2. Video lessons for 6th grade (grade 6)
  3. Multiplication tables (grades 3-4)
  4. Number sense (grades 1-6)
  5. Quilting and math - patterns! (grades 1-12)
  6. Angle theorems reference page (grades 6-9)

1. Math Mammoth news

I will be running the traditional Thanksgiving sale later this month! Stay tuned!

2. Video lessons for 6th grade

Here's a handy index or list of my video lessons specifically meant for 6th grade. You'll find topics such as percent, decimals, ratios, statistics, beginning algebra topics, and more.

3. Multiplication tables

It's probably that time where many are teaching the multiplication tables to their children or students. smile

Check out my guide of how to teach them. And here's a link to videos that do the "structural" (not totally random) drill for you:

Multiplication tables videos — presented in a specific order — easiest ones first — which makes learning them MUCH easier.

4. Number sense

Please watch this short video by Jo Boaler on NUMBER SENSE — the ability to work flexibly with numbers:

We need to encourage this type of thing with our children! The example she uses is a multiplication problem, but developing number sense starts earlier, with addition. For example, you can encourage your students/children to solve 8 + 9 using several different strategies, such as:
  • 9-trick: The nine wants to become ten, so it takes one from the eight. Thinking this way, 8 + 9 becomes 7 + 10 which is an easier problem.
  • doubles: 8 + 9 is really close to 8 + 8. If the child remembers that 8 + 8 = 16, then 8 + 9 is just one more.
  • Similarly, 8 + 9 is just one less than 9 + 9.

The same type of strategies can then be used in solving more complex addition problems. But the most important thing in this is that number sense has been proven to predict a student's success in algebra.

Check out Jo's video here.

5. Quilting and math - patterns!

Mathematics has been called the science of patterns, and here's another field that is all about patterns: QUILTING. Fascinating patterns and lots of eye candy!

Go check out this math teacher's take on a visit to a quilt show with tons of beautiful pictures. Enjoy!

6. Angle theorems reference page

I found a neat reference page about the important angle theorems, with visuals AND interactive versions:

It includes for example such basics as angles around a point add up to 360 degrees; vertical angles are equal; corresponding angles are equal; and results about the angle sum of a triangle, a quadrilateral, polygons; plus a few more.

Go check it out! I feel not only teachers, but students also might enjoy browsing through the page.

Thanks for reading! :)
