A Mathematics Lesson Starter Of The Day

Starter of The Day Transum Mathematics Topics


Topics: Starter | Logic | Mixed | Vocabulary

  • 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]
  • Dhruti, Sydney
  •  
  • This start up question really made my students think. Just wondering How to student voting system for this activity.

    [Transum: Great to hear that the questions made your students think. You could now try the pre-set questions on the Student Voting System.]

Teacher, do your students have access to computers such as tablets, iPads or Laptops?  This page was really designed for projection on a whiteboard but if you really want the students to have access to it here is a concise URL for a version of this page without the comments:

Transum.org/go/?Start=June24

However it would be better to assign one of the student interactive activities below.

Here is the URL which will take them to a student version of this activity.
