An interactive whiteboard resource to assist in teaching common multiples using a Venn diagram.  Select which two numbers you wish to generate multiples for.  Either you or the students can drag the tiles on to the diagram.  The tiles will glow red if they are in the wrong place and green if they are in the correct place

The resource should give you easy flexibility as you can choose which groups of multiples to work with with during the lesson.  This means you can tailor the activity to suit the students as you go without having to pre-plan for each eventuality.

This interactive whiteboard resource is intentionally fast paced to encourage students to estimate and consider what answer looks correct without necessarily working it out accurately. The fast pace also ensures a number of students can have a turn at the front of the class without taking up to much time.  Class questioning could consider what ways we can check whether an answer looks right.  I.e. adding 2 odd numbers will produce an even answer, rounding to the nearest ten and then adding for an estimated answer etc.

Borrowing the idea of diffusing a bomb from television drama the students need to connect the components together based on the addition questions and answers.  Click and drag from the question to the answer (or vice-versa).  Every failed connection results in sparks and a 5 second time penalty so accuracy is important.

This resource has sound so ensure your speakers are at an appropriate level.

As always if you encounter any bugs or problems please report it here.  If you like this resource and would like it applied to another concept or have a suggestion to improve it also leave your comment.

An interactive whiteboard resource for students to practice ordering numbers/fractions as well as a bit of logical thinking.  This resource simulates a slide puzzle.  Tapping a square next to an empty space moves it into that empty space.  The (difficult!) challenge is to order the squares so that their contents is in ascending order from the top left.  The rows follow the pattern demonstrated in the background image blocks i.e. smallest at the top left ascending to the right, then restarting on the left.  When the correct arrangement is reached the tile’s border changes colour and the tiles spin.  No more interaction is possible until “Go” is clicked again.  Note clicking “Go” restarts the puzzle at any time.

If you like this resource and would like further varieties please leave a comment with the 15 or 12 items that you would like ordering and the resource will be added for all to use. Words or numbers are possible although obviously length is limited.  Other comments or bug reports also welcomed.

One resource is a 4 by 4 grid and contains fractions to be ordered.  Go to Interactive Whiteboard Resource.

One resource is a 3 by 4 grid and contains multiplications to be ordered.  Go to Interactive Whiteboard Resource.

A number line designed for the interactive whiteboard.   Scroll along the number line by dragging the bottom bar.  Give it a flick and the physics will help get you to where you want, taking the chore out of a long scrolling number line.  This can also be used to select a random part of the number line as it will bounce back when it gets to the end.

Two number lines can be on screen to assist with teaching functions and number mapping.  The instructions can be selected by the teacher to give the class a visual reference when taking part in class questioning.  The number lines can be annotated with the built in screen writer and they will move along with the number lines.  Tap on an annotation to remove it click clear to remove all of the annotations.  Use the 1 or 2 button to select whether to show 1 or 2 number lines.

This is resource is as much an attempt to gauge how popular the physics driven interface on the IWB is as anything else.  It seems more natural to have real world responses on an interface you can drive by touch.  Think how you would find a country on a large globe.  Please leave comments and suggestions about the resource and regarding how you found the interface on an IWB.

This interactive whiteboard resource is for teaching how to find the lowest common multiples of 2 numbers.  The resource makes it easy to have two different, easily manipulated, multiplication tables on the IWB.  Each multiplication table can be rotated independently to demonstrate how to find the lowest common multiple.

The resource displays the first 15 multiples of numbers 2 to 15.

Slower computers may slow a little using this resource.

As always, any comments on how this resource may be improved or adapted, are welcome.

An interactive whiteboard resource to use for demonstration or questioning purposes with a class.  Select a number from 2 to 99.  Clicking “Go” will generate a prime factor tree for that number.  The numbers will be obscured by leaves which can be removed by clicking on the leaf.  This allows discussion on what the numbers will be before they are revealed.

Once all of the leaves are removed the prime factors can be pointed out.

An interactive whiteboard game to practise number properties. Thirty particles fall from above. Use the repelling particle to nudge them into the correct box depending on whether they contain a square number or a prime number. No points are scored if they miss both boxes. A point is deducted for the wrong box and a point is added for the correct box. Once all thirty particles have fallen the game is over. See who can get the highest score. Class involvement can be increased by allowing the audience to call out numbers and their property.

Quick thinking and a careful hand are required for this one!
