True

Sometimes

False

Angles in a triangle add up to 180o

x + 5 = 10

A shape with four sides is a rectangle.

The radius is equal to the diameter

x + 5 = 5 - x

5 ÷ x = x

x2 > x

An angle greater than 90o is obtuse

Place the statements in the correct section showing whether they are true, sometimes true or false.

• Jo Melville, Aberdeen

• Another great starter ... really makes the pupils think .. they had to be able to justify the positions - so no guessing allowed! Great for formative assessment - did all my pupils know that a decimal/fraction squared gave a smaller answer - No!!!!!
• Transum,

• Teacher, you can collect the opinions of everyone in the class about statements like these using the Student Voting System. Everyone will need access to an Internet connected computer and you can display the results with your projector.
• The Best Maths Class Ever 7cd/M2, King Alfreds Wantage, Oxfordshire
•
• We all found the starter a challenge. Personally I didn't understand any of it but I'm sure that a few people got there in the end. After sir stopped us he went through it and it became clearer to all of us. Some of us said they could of done it in their sleep (Molly!!) but others where soon put out of their misunderstanding.
A starter that really got our thinking caps on!
• Visitor,
•
• If you like these check out Andrew Jeffery's Book Always, Sometimes, Never. Great for discussion and encouraging the students to think.
• Matthew Tiller, EHWLC
•
• The "sometimes" box gets overcrowded! Also, it is not *always* true that a triangle's angles total 180 degrees: the exception is when it is on the surface of a sphere.
• Ms Furlong, Soar Valley College Leicester
•
• Space to "PARK" THE STATEMENTS to one side of the chart would be useful.

[Transum: Thanks for your comments, There is now room to park the statements]

## Have you read Craig's book yet?

Craig Barton must surely be the voice of Mathematics teachers in the UK. His wonderful podcasts interviewing the industry experts have culminated in this wonderful book. As Craig says: "I genuinely believe I have never taught mathematics better, and my students have never learned more. I just wish I had known all of this twelve years ago..." more...

"How I wish I'd taught Maths" is an extraordinary and important book. Part guide to research, part memoir, part survival handbook, it’s a wonderfully accessible guide to the latest research on teaching mathematics, presented in a disarmingly honest and readable way. I know of no other book that presents as much usable research evidence on the dos and don’ts of mathematics teaching in such a clear and practical way. No matter how long you have been doing it, if you teach mathematics—from primary school to university—this book is for you." Dylan Wiliam, Emeritus Professor of Educational Assessment, UCL.

## Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...

 Teacher, do your students have access to computers?Do they have iPads or Laptops in Lessons? Whether your students each have a TabletPC, a Surface or a Mac, this activity lends itself to eLearning (Engaged Learning).
