# Desmos & Valentines (& fractions and rotations!)

Great

It’s that time of year again – save your money and send your loved ones (or anybody!) a math-o-gram!

Click on the image and move that slider!

In what happily seems to have become an annual tradition Desmos have provided you with the means to send a math-o-gramto the mathematicians in your life!

Geeky people you could even use the Desmos API …

Valentine’s Day seems an appropriate time to express love for Desmos!
Two happy discoveries this week (thanks to Twitter):

Multiplying fractions and Rotation about a point. Brilliant.

Elsewhere – express your feelings for WolframAlpha!

Wishing Mathematicians everywhere a happy day and if you are a UK teacher about to start half term – have a lovely week!

We used to teach students cos0=1
Did we ask our self how?

When the degree is 0, there will be no  opposite side,at the same time hypotenuse and adjacent will be same.
So cos0=1

Let us think to make our students always cos0.

# Make Learning Meaningful in 2015

Today i have gone through an article clearly says about meaningful learning.

In this article one line says about traditional way of giving worksheet to the students and then asking them to sit in disciplined way to solve ,which is not the only of making learning happens but also making students go around discuss/realize which some teachers never tried ( because teachers think that it will be messy) according to my knowledge.
