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 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 16 March 'Starter of the Day' page by Mrs A Milton, Ysgol Ardudwy:

"I have used your starters for 3 years now and would not have a lesson without one! Fantastic way to engage the pupils at the start of a lesson."

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 There. I feel obliged to question one of your answers there. Surely 9.846 rounded to one decimal place has to be 9.9. The 4 becomes a 5."

"Hi Logan. When rounding to one decimal place you only have to consider the value of the second decimal place. You can ignore the rest of the digits.
To make it clear have a look at the diagram below. You can see that 9.846 is closer to 9.8 than it is to 9.9. Therefore it makes sense to round it to 9.8.
