Why am I learning this?

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 23 September 'Starter of the Day' page by Judy, Chatsmore CHS:

"This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles."

Comment recorded on the 1 February 'Starter of the Day' page by Terry Shaw, Beaulieu Convent School:

"Really good site. Lots of good ideas for starters. Use it most of the time in KS3."

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.

"Hi,
I am not sure if it is my computer but when I enter an answer some of my answers are changed and are then wrong.
I liked this resource but this problem makes it difficult to use.
Thanks.

[Transum: Sorry to hear that Karen. I have not been able to reproduce that problem from this end. If anyone else experiences a problem please let me know. It may be something on your computer Karen]"

"Hi,
My students have been having the same issue where they put the right answer in but then it changes it and shows that it is wrong.

[Transum: Hello Trisha. Thanks for leaving this message. I am still unable to reproduce the problem. I wonder if someone could give me some more information about when this problem occurs. Is it when the Check button is clicked. Is it when the mouse scroll wheel is used? What value are the answers changed to? What type of device is being used? What browser is being used. Any other ideas gratefully received. Thanks]"
