A great tutorial explaining how to use autograph to investigate straight line graphs. It is very clear and has lots of ideas as to how to use this software in class. The 25th in Mr Barton's Autograph Video tutorial series. Here we look at two different approaches to investigating the equations of straight lines on Autograph, both of which make good use of Autograph's excellent dynamic textboxes, and one which uses the Constant Controller.

Algebra Level 7: students will need to calculate gradient. Must work out the equation of the straight line from a selection of co-ordinates that lie along it.

An idea for a starter activity to engage pupils. It contains possible extension activities.

A puzzle for the classroom wall, which could maybe form part of some kind of weekly competition.

An excellent lesson on discrete random variables, following the SMP S1 book, kindly donated by Lisa McNulty.

“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

This is a rich Venn Diagram activity on operations with negative numbers. To access all the Venn Diagram activities in this collection, as well as teaching notes, please visit: http://www.mrbartonmaths.com/venn.htm Here is why I love Venn Diagram activities so much: 1) Students can always make a start. If they can think of a number/expression/object or whatever it might be, it has to go in one of the regions on the diagram, so they are up and running 2) The more regions student find, the more challenging the task gets, which adds a nice element of differentiation 3) They are incredibly versatile, and can be used for almost all maths topics for all ages and abilities 4) They are easy to tweak by simply changing one of the circle labels if you find they are too difficult/easy 5) Students can create their own as an extension task I hope you and your students enjoy them.

A set of Starter Cards on powerpoint from the wonderful liverpool maths team. The idea is that you print out the cards, laminate them, and use the prompts on the back to engage the pupils in a stimulating discussion.

Lots of questions and answers testing all types of rounding.

A jigsaw containing some pretty easy and pretty hard place value questions.

An infinite number of examples for working out the circumference given the radius/diameter and vice-versa.
