### 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!

### Number sense

A short video on NUMBER SENSE - the ability to work flexibly with numbers.

We want to encourage this 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.

### Angle theorems reference page

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

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.

### In my room

Reading the news day after day in these times can be so troubling... I love this peaceful song and the thoughts in it...
