True or 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 รท 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]
