multiplication dice game

Image via Wikipedia As I was surfing through the blogosphere last week I stumbled upon a fantastic blog post explaining a fun game that you can encourage the pupils to play to practice their times tables. The inventor of the game is Dan Finkel, the author of the fantastic math for love blog.
Image via Wikipedia Here is a superb plenary for a lesson about multiplying and dividing by 10, 100 and 1000. This resource consists of two files. The first is a PowerPoint presentation that runs a game of Who Wants To Be A Millionaire. The Second is an Excel Document that gives pupils a worksheet to record their successes and failures on. http://www.greatmathsteachingideas.com/2012/02/26/multiplying-and-dividing-by-10-100-and-1000-who-wants-to-be-a-millionaire/

Highest Common Factor Domino Puzzle

Image via Wikipedia With pupils on the lower end of the attainment spectrum I like to teach calculation of the highest common factor of a pair of numbers by the method of writing out the factors of each number, highlighting the common ones and then choosing the highest. I find this more successful than teaching them to use prime factorisation. Whilst this has the disadvatange of not being suitable for large numbers, I’ve yet to see a GCSE question that asks for HCF of two numbers that are too large to use the simpler method. To add a nice change from simple ’10 questions’ worksheets I decided to put together the domino puzzle below based on finding HCF for relatively small numbers for one of my year 10 groups.
