Sometimes I start with a simple thought on Twitter, decide to take it to the next level, and before I know it things have gone entirely out of hand and I’ve gone from a simple tweet about missing NY bagels to a fully produced bagel love song posted on SoundCloud in a matter of hours. This time, it started with some simple microwave advice. I ended up live-tweeting while I made a video in 2 hours, and I figured I should get it all formatted in a post before it disappears into the unsearchable depths of twitter forever. Might as well add some further details on what went on too, if you’re interested in a thorough case-study of how one might go about making a weird video. Yes, let’s get way too in-depth! It will mirror the unreasonable nature of the art itself!

Making Maths: Clinometer A clinometer is a tool that is used to measure the angle of elevation, or angle from the ground, in a right - angled triangle. You can use a clinometer to measure the height of tall things that you can't possibly reach to the top of, flag poles, buildings, trees. Follow the directions below to create your own clinometer. You will need: A protractor with a small hole on the centre spot orPrint out of paper protractor (see below)Poster board or card board (can be from a box) to back the protractor20 cm or about 8 inches of string or strong cottonWeight - such as a metal nut, paper clips or a small piece of clayGlue and ScissorsA strawClear TapeItems marked with the red check are needed with either type of protractor.

How to learn to love maths Britain is about to fall in love with maths. Well, that's the dream. Yesterday one of the government's top advisers on further education said that maths should be compulsory for all students until 18 or 19 – no matter what else they are studying. Professor Steve Sparks, chairman of the Advisory Committee on Mathematics Education, also said that he wants a new maths qualification between GCSE and AS-level to be introduced by 2016. Maths is justified in this country because it is useful. Sparks said his proposals were necessary because young people need a better grasp of maths to compete in the job market, where an understanding of technology and numeracy are increasingly important.

Learning to love math Recently I wrote about how we have been struggling with Kyri’s attitude. Often when we would start working on our math work for the day, she would immediately get huffy, turn around in her chair and just completely shut down. I know she is a bright girl, and so it would pain me to hear her say she hated math, because I know she GETS it, her frustration just gets in the way. I have been working to really listen to her, to try and figure out what she needs, rather than just respond to the behavior. Some days this is easier said than done, but overall we have made significant process.

Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Click on the Auto button to return to the Automatic mode.

#TMC14 GWWG: Talking Points Activity – cultivating exploratory talk through a growth mindset activity This activity is the one I am most excited about bringing to #TMC14 and to the Group Work Working Group. My intention is to blog more about how this goes during the morning sessions. I also hope that participants will blog more about this too and contribute resources to the wiki. 6 Ways Learning Math Is Like Being in a Casino I’m in Las Vegas for the DevLearn conference this week. Since I’m always thinking math teaching and now I’m seeing casinos, I’m noticing some comparisons between the two. Here they are: You don’t know if you’ll be successful when you sit down at the table.

Mathematical Mindset Teaching Guide, Teaching Video and Additional Resources We have designed a Mathematical Mindset Guide to help teachers create or strengthen a growth mindset culture. This guide contains five Mathematical Mindset Practices along with links to teaching videos. The videos all show Jo and Cathy teaching middle school students. Mental Math Tricks to Impress Your Friends One thing that fascinates me is performing mental math. Being able to quickly perform additions, subtraction, multiplications etc is a good way to impress your friends. The problem is, I’m not a math genius, and I don’t know much behind simple arithmetic. If you’re anything like me, but you’d still like to learn some basic math tricks, I hope you’ll find this list useful. Simple tricks How to multiply any two digits number by 11

Operation Build a Bridge and Get Over It - Activity Summary Students act as structural engineers and learn about forces and load distributions as they follow the steps of the engineering design process to design and build small-scale bridges using wooden tongue depressors and glue. Teams brainstorm ideas that meet the size and material design constraints and create prototype bridges of the most promising solutions. They test their bridges to see how much weight they can hold until they break and then determine which have the highest strength-to-weight ratios. They examine the prototype failures to identify future improvements. This activity is part of a unit in which multiple activities are brought together for an all-day school/multi-school concluding “engineering field day” competition.
