[|Soma Dra – isometric drawing of soma cubes.]
This interactive whiteboard resource can be used as part of the Soma Cube themed resources on this site or as a standalone resource for demonstrating how to draw using isometric dotted paper. By clicking the appropriate button either a piece from the Soma Cube or one of the shapes it can make are shown along with a an isometric dotted grid. Students and teachers can demonstrate how to draw the shape isometrically using these. To draw click and hold on a dot and move to another. Once you touch another dot the line will be straightened and you can progress to the next dot. If you make a mistake click undo to step back through the lines.

[|Soma Bingo – use soma cubes competitively.]The third interactive whiteboard resource in a series to aid using Soma Cubes in lessons. This one is to facilitate adding a competitive element to their use. Break the class into groups and allocate them to one of four colours red, green, yellow or blue. Set a goal. This may be to complete a horizontal line, vertical line or any line. When a group shows you that they have completed a shape they can capture that square by pressing the appropriate colour on the appropriate box. That square is then captured for 2 minutes or permanently if you activate that option. To take take a closer look at a shape click the small picture inside the box. Click the larger picture to close it. There is far more detail on how to use this resource on the teacherledplus.com link below. Go to Soma Bingo Interactive whiteboard Resource. To learn more about using Soma Cubes in lessons for practising spatial awareness and problem solving skills see this the supporting site to teacherLED.com – teacherledplus.com [|View Soma Cube Introduction IWB resource.] Soma Isometric Drawing



[|Soma Intro – Introduce the Soma Cube to a class.]This interactive whiteboard resource forms the first part of a themed series of resources that support the use of a Soma Cube in teaching. If you know about the Soma Cube then this resource is useful for showing a class the basic pieces and some of the shapes that can be made from them. Choose either shapes that can be made from a set of Soma pieces or the individual peices themselves and scroll through them using the arrows at the bottom of the screen.



[|**Difference Triangle** – Mathematics puzzle.]
This IWB resource is designed to introduce students to the challenge of completing a Difference Triangle. If you want to introduce a problem based lesson this resource should save you some planning and preparing time. This resource can be used to show students the concept on the IWB. When a student has solved it their answer can be checked by entering it into the resource. If it all turns green it is correct. It can also be used for the focus of a group based attempt to solve it. In the completed triangle each number is the absolute difference of the two below it. For example 5 is the difference between 4 and 9 and it is the difference between 9 and 4. In effect it is the higher number minus the lower number. On this resource a number that is the difference between the two below it will illuminate green. This does not mean that the numbers are in the correct place. It only means that the difference is correct. The bottom numbers are independent of other numbers so will always show green. This is a problem that requires a lot of work to solve but rewards thinking the problem thr0ugh. For example the students would do well to realise that some numbers must be at the bottom as no other numbers can have them as a difference. To move numbers select one that you require moving and then click anothertile which is where you would like it to move to. They will then switch places.



[|**Fraction Comparison** – compare fractions on an IWB.]
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.
