Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College:

"Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work"

Comment recorded on the 5 April 'Starter of the Day' page by Mr Stoner, St George's College of Technology:

"This resource has made a great deal of difference to the standard of starters for all of our lessons. Thank you for being so creative and imaginative."

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

"I wrote this activity for a friend's daughter who was struggling to see the angle relationships in her school homework. I presented it to her as this self-checking digital version because if she tried the more traditional paper versions she would not get the immediate feedback the computer provides.

We did level one together. She typed in the answers in the web browser but had a laminated copy of the printed version in front of her to draw on (Great for seeing the Z shapes).

After Level 1, she was feeling more confident so we played Level 2 as a game, taking it in turns to figure out one of the angles. She was most confident with vertically opposite angles and angles in triangles. A blank sheet of paper to hide the unnecessary part of the diagram helped her spot the angles together on a straight line. At one point, using her own initiative, I found her looking in her school exercise book to remind herself about angles in quadrilaterals and pentagons.

This was one of those great teacher moments when you can see the understanding taking shape and the pride the student demonstrates when solving mathematical problems.

I hope this activity works as well for you. "
