A session in which the focus is on solving a set of mathematical problems
An opportunity to show off your maths skills
Key to a successful meetingEveryone should feel comfortable and welcome to contribute
Suggested meeting formatWorking in small groupsLooking at a new Nrich problemBrain storm/sharing ideas on how go teach this problemSharing ideas with all the departmentImplementing in class
Todays problem:Consecutive sumsMany numbers can be expressed as the sum of two or more consecutive integers: 15=7+810=1+2+3+4
What can you say about numbers which canbe expressed in this way? Try to prove your statements
Which class or classes would you teach this problem to?Nrich asks: What can you say about numbers which can be expressed in this way? Can you think of other questions you might ask your learners in relation to this problem?How will you differentiate?Which department resources can you use to teach this problem to lower and higher ability groups?
The hints: Start by trying some simple cases. Which numbers can be written as the sum of two consecutive numbers? Which numbers can be written as the sum of three consecutive numbers? Which numbers can be written as the sum of four, five, six... consecutive numbers? Can all numbers be written as the sum of consecutive numbers? 1+2+3=6 so 2+3+4 must add up to 3 more.
Will you introduce the hints to your classes? If so, how and when will you do this?
