## A Mathematics Lesson Starter Of The Day

Topics: Starter | Indices | Logarithms

• 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!

• Ryder Craig, Linwood Avenue School, Christchurch

• If you want the answer I guess you have to read the question carefully.

## Maths Trivia

The digits of the number are the same as the digits of the power of ten in these cases:
