This interactive whiteboard resource provides a companion for the Decimal Comparison IWB resource.  It works in exactly the same way.  The students have 30 seconds to show which of a pair of fractions is greater than or less than the other by drawing on the appropriate signs.  Correct answers gain a point;  incorrect answers  lose a point.  After clicking ”Go” two fractions will appear.  The blue rectangular background is a drawing canvas that will detect which of the two signs “<” or “>”  has been drawn by the students. 

This resource might be used as a plenary exercise or a revision game.  As with all of the resources on this site it is designed for use on the IWB at the front of the class.  Drawing the signs is easier on a whiteboard than with a mouse.

This interactive whiteboard resource is intended to allow students at the interactive whiteboard to demonstrate their ability to compare numbers to varying decimal places.  It also allows practise at remembering which sign is which between the < and > signs.  After pressing start various decimal numbers will appear the student must then write a > or < on the large blue square.  The software will then recognise which of the 2 signs has been drawn and award a point for a correct answer and remove one for an incorrect answer.  As the IWB resource analyses a drawn sign rather than a button press this resource is much more natural to use with an IWB rather than a mouse and screen.  It is hoped that the drawing of the signs will be more effective in reinforcing knowledge that pressing buttons with the signs on them.

 The character recognition on this resource is not working too hard to distinguish between only 2 signs so it is quite forgiving.  It is up to the teacher to set rules on correctly formed signs.

Please comment on how you have found this resource and report any errors.  Note on the picture it looks like an answer has been marked incorrectly.  The “correct” is for the previous question and is fading out!

An interactive whiteboard resource that you may find useful for practising multiplication tables with your class.  It is intended to support children in visualising what multiplication does.  The rainbows illustrate the counting on technique and the raindrops show the number of sets in the multiplication.  Led by the teacher, a  class  can work through each multiplication table tapping it to confirm the group’s answer with the appearance of the next rainbow.

At the bottom of the screen you will see a scroll bar.  Tap above this to move one along on the currently selected multiplication table.  The next rainbow will appear as well as the raindrops.  Holding and dragging the scroll bar will allow you to advance through the multiples (unless you have tapped enough times to make all of the rainbows appear some or all of this will be blank).  Or you can flick the scroll bar for it to move quickly to the opposite end.

Changing the multiple amount or pressing clear will make the rainbows and raindrops dissappear ready to start again on either the same or a different multiplier.

Suggestions, comments, problems are appreciated in the comments section.

A paper copy of the chain of rainbows can be downloaded here for student use.

A  numberline that shows negative numbers for the interactive whiteboard.  It ranges from -50 to +50.  The numbers are categorised by colour with negative numbers underscored by red, and positive by black.  Which isn’t particularly asthetically pleasing but does reflect the financial phrases of “in the red” to represents debt etc.

You can annotate dirtectly onto the line using the built in writing tool.  These annotations will then scroll with the line as you move it about.  Scroll the numberline using the bar at the bottom. It has realistic physics built into it so the line can be quickly flicked from one end to the other.

Go to the Negative Number Interactive Whiteboard Resource.

This resource could be used in conjunction with this Temperature Comparison IWB resource for teaching negative numbers.

Comments on the resource’s use are welcomed below.

A function machine interactive whiteboard resource.  Children seem to enjoy the concept of the numbers going through a process to be converted on a function machine.  Borrowing a graphical style from computer games this function machine IWB resource lets you set one or two function machines.  Click on the number and it will go through the function machine conversion process.  If the number is on the left it will move right going through the process to become the output.  If it is on the right the process will be reversed to go back to the input number.

The single blue button brings up a control panel.  From here you can determine the input numbers’ start value.  The number of functions lets you toggle between one or two function machines.  The hide details lets you disguise the the functions, input numbers and operations.  Of course, this means that while you can hide all of this from your class you’ll have to count your clicks to know what you are entering.  The numbers are also reset by opening and closing the panel.

To enable the whole class to work along with the IWB resource there are a couple of printable resources in a similar style.  On these the students can enter the start numbers and then the finish numbers after the process is complete and try to predict what the functions are.

On a technical note the particle effects in this resource may be a strain for older computers especially on larger numbers which don’t really suit the resource but are possible as outputs.  While the resource is new please check that any combination of numbers you wish to use in lesson work okay as there is quite a lot going on behind the scenes of this resource and it is impossible for all of the combinations of numbers and actions to be checked for bugs.  If you notice any problems or graphical glitches please comment with problem, the numbers that the problem was caused by, an if you know it, your screen resolution.  Other comments are welcome too.

An update to the most frequently used interactive whiteboard resouce on this site.  A variety of measuring devices can be shown on the screen grouped together in themes.  Use the arrow buttons to select between them.  Click the “New” button to generate a new set of readings.

More than one device is shown on screen to allow for the differentiation between abilities during a class questioning session.  Some devices have more complex demarcation than others.  Some devices will always move to a whole mark on the scale others allow a measurement to fall in between.   Those devices where the demarcation may be difficult to read from a distance use a magnifying mechanism alongside them.

Reading scales 2 interactive white board resource.

The original reading scales resource.  On the whole this uses more straightforward scales so may be useful for introducing the concept.

If you have any suggestions for new measuring scales for this resource or encounter any problems please leave a comment.

An interactive whiteboard resource to demonstrate sorting groups of factors  using a venn diagram.  This resource could be useful when teaching highest common factors.

Use the arrows to change the number to generate factors for.  Drag and drop the tiles to the correct position on the venn diagram.  They will illuminate green when correctly placed and red when incorrectly placed.
