An interactive whiteboard resource to demonstrate the measuring of angles to a class.  The two black lines can be moved to create varying angles.  The arcs signifying the angles in question can be toggled on or off leaving one or both on display by using the two buttons with the red and blue arcs in them.  There are two type of angle measurer that can be used: a 180 degree protractor and a 360 degree angle measurer.  These can be toggled by the appropriate buttons on the display or removed by using the very top button.  The angle measurers can be rotated by clicking and dragging.  They will always be centred over the point where the lines meet. 

Using this resource you should be able to realistically demonstrate the measuring of angles.

An interactive whiteboard to demonstrate rotation around a point to your class on an IWB.  The small black cross is fixed as the point of rotation in the centre of the screen.  Click the red shape to move it around the screen.  On release it will snap to alignment.  Clicking and dragging the vertically aligned slider to the right will take the shape through its rotation around the centre point.  Releasing the slider will snap it to the nearest 90 degree rotation.

You can choose between rotating a square shape or an L shape using the button below the slider.  The button with a circle toggles the path of rotation on and off.  The four pale blue discs canbe dragged and dropped to mark key points.  For example you could mark the original top left corner of the shape and where it is expected to be after a 90 degree rotation.

A printable resource is also included for students to cut out and predict what they will think will happen during different rotations.

As an additional function the outer red wheel can be freely spun by pulling quickly and releasing and this will spin the hands of the clock to a random time.  This function will be easier on an interactive whiteboard than with using a mouse.

EDIT: I have now added a clock for when you want to introduce roman numeral clocks. This one references the clock that often has the name of its bell extended to it, Big Ben. There is still a rotating bevel on this on and it works like the simple clock. The bevel is invisible unless you start to drag it.

NOTE:  A list minute change has introduced a bug into the rotation making the hand’s movement choppy.  This will be fixed today.  Fixed!

Teach the translation of shapes using this interactive whiteboard resource.  Click on one of the shape buttons to the right of the grid to display the corresponding shape in a random position.  A set of instructions for translating this shape will also appear in the blue box.  Drag and drop the four circular markers to the translated position of the shape’s corners.  If they are placed in the correct position the translated shape will be drawn on the screen.

The instruction box can be dragged to convenient locations on the screen.  The translating instructions can be set to words or vectors or both.

Please report any errors in the comments section.

An interactive whiteboard resource to practise visualising clockwise and anticlockwise rotations.

When you click on “go” the clock face will be obscured.  When it is shown again the numbers will be hidden.  The blue box at the side tells you how many degrees the clockface has been rotated by and whether the rotation was clockwise or anticlockwise.

The rotations are always in multiples of 3o degrees. Clicking “show” will reveal the clock’s numbers and the answer.  This would probably be useful as a plenary activityafter a lesson on rotation.

Any comments are welcome as are error reports and suggestions for improvement.

This interactive whiteboard resource is inspired by one of the entries in the book: Professor Stewart’s Cabinet of Mathematical Curiosities by Ian Stewart.

It focusses on repeating tiles where duplicates of a shape combine to form a larger version of the same shape.  The picture above shows one such shape about to be completed.  This can form part of a lesson on tessellation or investigating shape properties.

Each tile has 3 icons on it.  One to drag it, one to rotate it, and one to flip it.  The icons down the right hand side let you choose one of 7 different types of repeating tiles.

Also included is a collection of the shapes that can be downloaded, printed, and cut out so that the students can work individually on solving each shape.  Some of the solutions require the shapes to be flipped so their reverse could be shaded by the students first.

This interactive whiteboard resource is the result of a suggestion in the comments on the Number Line IWB resource.  The suggestion was to adapt the number line to allow it to be used to show elapsed time.  The result is this interactive whiteboard resource.

There are 2 clocks that have draggable fingers to set a ‘from’ and ‘to’ time.  The number line shows whole hours and 15 minute intervals.  You can annotate directly to this using the built in annotation and your notes will scroll with the number line.  Using these tools you can demonstrate how to use a number line to calculate how much time there is between 2 given times.

Like the Number Line resource the interface for this resource uses physics to allow you to use inertia to scroll along the number line by dragging on the bottom bar.  It is hoped that this method is more natural for use on the IWB (but it is not so conducive to mouse control).  Unlike the Number Line resource this number line does not bounce at the end of the scroll.  Comments on the interface or further suggestions for development are welcome.
