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?

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.

"Apologies for the fact that the rotation of the measuring instruments does not work in older versions of Internet Explorer (version 8 and previous versions). Apologies also that this activity is not very functional on an iPad due to the lack of a shift key."

"The ruler is inaccurate showing 2 cm as 1 cm.

[Transum: Thanks for your feedback Fiona. I have looked at the image of the ruler and to me it looks correct. Maybe you are referring to how big 1cm looks on your screen - that will depend on the size of your screen and the current zoom level. If projected onto a screen 1cm will be huge! Am I missing something do you think?]"

"The diagonal of the house from the corner of the laundry to the corner of dining room. we tried to answer this question about 75 times and we could not get the answer right. You should specify which corners we should measure rather than naming two rooms. Could you please tell us the answer to this question?

[Transum: Hi Joel, John, Leslie and Wilson. Seventy five attempts makes me think you are very determined. Well done. The question asks you to find diagonal of the house so that should give you a clue as to which corners of the rooms you should be using. I have just tried doing this question and got it right on my first attempt. I rotated the ruler so that I could measure the distance, in centimetres, from the bottom left corner of the laundry to the top right corner of the dining room (inside the walls). I multiplied this measurement by the scale factor of 250 then I divided by 100 to convert to metres. Finally I rounded my answer to one decimal place as instructed. Did you miss out one of these steps?]"
