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!

Based on the same idea as a number of newspaper puzzles. Take a starting number and apply a set of instructions to it to achieve a finishing number.

Click create to generate a new start number and instructions. The start number will not appear. A feature of this resource is that you can choose whether to show the start number or the answer. Showing the answer modifies the puzzle so that students have to do the inverse of the instructions to find the start number.

A timer can be applied. The length of time available for each instruction can be adjusted. When the length of time has passed a light appears below the instruction to show the students that they should move on.

What happens when the time runs out is left to the teacher. You can minimise the display to hide it.
You cannot run the timer if both the answer and starting numbers are shown as there is no point. If the answer is shown the lights will run from bottom to top. If the starting number is shown the lights will run from top to bottom.

Note:
The instructions are generated randomly to give a large variety of puzzles. The randomness is tempered by a set of rules to avoid going into complicated decimals. The downside to this is that sometimes the rules can result in less satisfactory puzzles where a number is doubled then halved then doubled etc. Just click create until a satisfactory sequence emerges.

A simple resource for use in class questioning. It can be used by history/primary teachers who would like some cross-curricular work. It can be used by Maths teachers demonstrating how and why the number system evolved.

Click on create to generate 2 roman numeral numbers for addition. It would be useful for students to have mini-whiteboards. Encourage them to try and work purely in roman numerals to demonstrate the failings of this system. The students should notice that the lack of place values is quite a hindrance and prevents column addition. Clicking answer brings up the answer and a translation into modern numerals.

Note that for consistency the roman numerals generated in this resource use the addition method which is supposedly the one used by early romans. For example 9 would be VIIII rather than IX. Both are methods are equally valid but this resource uses the former.

An interactive whiteboard resource designed to assist teaching simple number sequences. A new sequence can be generated instantly. Each number of the sequence can be revealed one at a time to allow class discussion about what could be next.

The resource will generate either an addition or subtraction sequence on the bus numbers. Due to the simplicity of the sequences generated this resources is probably best used with younger children and the visual presentation reflects that. This resource also has sound so ensure the volume is set appropriately.

Go to interactive whiteboard resource.

A sheet containing rows of blank buses is attached to allow students to record the sequences on paper as they go.

From an experiment in trying to make a number line that looped back on to the screen came Number Cylinder. An interactive whiteboard resource that could prove a useful alternative to using a traditional number line as it provides some of the features of a 100 square too.

Click and drag on the screen to rotate and change position. Double click the screen to to increase the horizontal distance between the numbers. Dragging in the centre of the screen produces smaller movements in the Number Cylinder, this is marked by the concentric circles.

This resource is predated by a physical version: The Numdrum. To find out more about this resource visit the Numdrum site.

Go to learning resource. (Positive numbers only)

Go to learning resource. (Negative numbers as well)

If you prefer traditional number lines try these number lines.

As an additional resource for teaching negative numbers. Use temperature comparison resource.

An interactive whiteboard starter to practise mental or written maths. Issue the class with mini whiteboards or paper and pens to do their working out on.

Click 30 or 60 to determine how long they have between new questions. The train will arrive. The timer will start. The students then need to take the starting number shown on the red flag and apply the calculations shown on the carriages. When the time reaches zero the train will leave and a new one will arrive. Four trains will arrive and leave before the end. At the end, click “check” to see the trains with their answers. The resource is fully automated so is a useful activity to set while marking the register.

Also included is a worksheet with blank trains either for the students to use in their working out or for teacher created questions.

Remember to use F11 in Internet Explorer or Firefox to go to full screen as this resource is a little larger than usual.

Designed for the interactive whiteboard. A game to allow students to demonstrate that they can distinguish number groups.  The resource presents ten bubbles bouncing around the screen.  The first version of this IWB resource has 5 prime number bubbles and 5 non prime.  The challenge is to burst all of the primes in as short a time as possible.

For younger students the second version has the same concept but presents odd and even numbers.  The student needs to burst all of the odd numbers.

The resource is primarily designed to be used with an interactive whiteboard and so may be a little trickier with a mouse.

 As a side note reference can also be made to science lessons ; the bubbles simulate the refraction of light.  This is an effect that may labour slower computers.
