A Mathematics Lesson Starter Of The Day


Share

Topics: Starter | Indices

  • Transum,
  •  
  • At the time of writing this is a new starter idea. It is intended for pupils who can confidently understand the facts in the left column but may need to consider some of the unfamiliar facts in the lower part of the right column leading to discussion or research (on a calculator maybe). Of course this starter would also be suitable for older pupils who already know about indices less than one. What was the reaction when you revealed the answer?
  • Josh Hand, King's Worcester
  •  
  • Excellent - well done. The more of these the better.
  • Dana Issam, UAE
  •  
  • I think the error is in the 2^4, all of the other sums are related to the rules of indices.
  • Peter Wright, St Joseph's College
  •  
  • Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities.
    Thanks for such a great resource!
  • Alice, Wisconsin

  • I can't spot any mistakes. What is the answer, please.

Texas Instruments Nspire Calculator

This handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TI-Nspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TI-Nspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others.

For the young people in your life it is a great investment. Bought as a gift for a special occasion but useful for many years to come as the young person turns into an A-level candidate then works their way through university. more...
