# Autograph Video 67 – Pizza Puzzle

The final part of the Autograph Puzzle Trilogy! This week we take a look at the “Pizza Problem” — what is the maximum number of pieces you can cut a pizza up into making straightContinue reading

# Autograph Video 66 – Quadrilateral Puzzle

The second of the Autograph Puzzle Trilogy! Here we look at another a lovely pencil and paper puzzle inspired by Don Steward’s amazing Median Maths Blog. Students are given four co-ordinates and asked to considerContinue reading

# Autograph Video 65 – Leap Frog Puzzle

The first of the Autograph Puzzle Trilogy! Here we look at a lovely pencil and paper puzzle inspired by Don Steward’s amazing Median Maths Blog. Place any 3 points on a page and start leap-froggingContinue reading

# Autograph Video 64 – Matrix Transformations

Should you find yourself needing to teach the transformation of matrices, it would be nice to have some dynamic geometry package to help you along the way through this very visual topic. This is whereContinue reading

# Autograph Video 63 – Line Symmetry in Quadrilaterals

This is the much-anticipated(!) sequel to last week’s Line Symmetry in Rectangles. Here we look at how we might create an Autograph page to look at line symmetry more generally by allowing us to alterContinue reading

# Autograph Video 62 – Line Symmetry in Rectangles

A common misconception amongst students (and myself, actually!) is that a rectangle has 4 lines of symmetry. In this video we look at how we can use Autograph to illustrate this concept in a simple,Continue reading

# Autograph Video 61 – Circle Through 3 Points

I was surprised that one of my Year 13 students wasn’t aware of the lovely fact that you can draw a circle through any 3 points, so long as those 3 points do not lieContinue reading

# Autograph Video 60 – Battleships

In this video we take a look at an activity I like to use with my classes called Co-ordinate Battleships. I use this either to revise the equations of straight line graphs or even toContinue reading

# Autograph Video 59 – Importing Images

Another incredibly useful feature of Autograph is the ability to import images onto the graph page. In this video we take a look at how easy it is to import images into Autograph, and thenContinue reading

# Autograph Video 58 – The Keyboard

A feature of Autograph that many people are unaware of (or close down as quickly as possible!) is the Autograph Keyboard. In this video we take a look at some of the useful things thatContinue reading

# Autograph Video 57 – Hiding Things!

An incredibly useful feature of Autograph is the ability to hide a variety of things. These include points, shapes and lines. In this video we look at how to hide objects and then suggest aContinue reading

# Autograph Video 56 – Follow the Point

The Transformation of Functions Trilogy comes to a close with this final video all about how you can use Autograph to play “Follow the Point”. Being able to predict the co-ordinate of a point followingContinue reading

# Autograph Video 55 – Transformation of Functions 2

Part 2 of the Transformations of Functions Trilogy of Autograph videos. This time we take a peek at a nice way of getting the exact shape function you are looking for without having to worryContinue reading

# Autograph Video 54 – Transformation of Functions

The first in the Transformations of Functions Trilogy of videos where we look at how we can use Autograph to introduce students to the topic of transforming graphs. We see how to enter the f(x)Continue reading

# Autograph Video 53 – Creating Number Lines

Following on from our work on worksheets last week, this time we take a look at how Autograph can be used to very quickly create an incredibly flexible number line. This can then be usedContinue reading

# Autograph Video 52 – Creating Worksheets

Just a quickie here about how you can use Autograph to add that finishing touch to your perfect worksheet. Whether you want a lovely set of axes, some square paper, or some old fashioned graphContinue reading

# Autograph Video 51 – Fitting Functions to Data

Following a request from Science teacher Mr Richardson, here is a video explaining how you can use Autograph to fit functions to various data sets. It doesn’t matter if the relationship in your data isContinue reading

# Autograph Video 50 – Further Volumes of Revolution

In the final Autograph Video of 2011 we take a look at some of the lovely shapes you can make using Volumes of Revolution. We hint at how it is possible to derive the formulaeContinue reading

# Autograph Video 49 – Volume of Revolution Formula

Following directly on from Video 48, this week we look at how we can use Autograph’s unique 3D engine to demonstrate to students exactly where the formula for the volume of revolution comes from. ThisContinue reading
