Several mental arithmetic mini-tests with answers and infinite questions.

This is a great interactive activity in excel that generates random linear sequences and asks pupils to find the nth term. Suitable for KS3 and KS4 students.

You type in a set of numbers, and excel works out the mean, median, mode and range whenever you click the buttons.

This a rich, Arithmagon activity on Adding Fractions. I love Arithmagons as they allow consolidation of key topics when going Forwards, and then opportunities for extension, creativity and discovery when working Backwards. They are also really easy to modify to suit the particular needs of your class. For all the Arithmagon activities in this series, together with teaching notes and extra information, please visit http://www.mrbartonmaths.com/arithmagon.htm

given a random starting number, students must substitute into a variety of linked expressions. comes in two levels of difficulty and clicking the boxes gives the answers

“Build an Army” is a fun, strategy game that can be used to consolidate understanding of key mathematical concepts. After students have played the game and described their strategy, there are opportunities for differentiation via various lines of inquiry and probing questions for the students to investigate. Full instructions are provided in the “General Rules” PowerPoint. To find more Build an Army activities, just visit: http://www.mrbartonmaths.com/buildanarmy.htm

SSM Transformations Level 5 To be able to recognise the order of rotational symmetry of any shape. A simple animated presentation to demonstrate rotational symmetry to students

A lesson teaching the basics of stem and leaf diagrams with a nice colourful example.

A demonstration of how to rotate shapes with tracing paper. Objective: To be able to Rotate a shape around a given point

Algebra level 6 Powerpoint: An introduction to solving equations using the balance method

a simple worksheet on enlargement using axes, co-ordinates and positive integer centres of enlargements

Have a play around with this task, and please share any questions, extensions, simplifications, modifications, or lines of inquiry in the comment box below. The idea is to collect loads of suggestions that can then be used for effective differentiation.
