This is a visual aid designed to be projected onto a whiteboard for whole class exposition. It doesn't need to be an interactive whiteboard though of course that will make the resource more dynamic. The title "Shine+Write" suggests that the teacher or student can write on the whiteboard to enhance this visual aid.
The Transum Pin Board provides many ways to investigate two dimensional shapes. Clicking on the dots allows students or teachers to create shapes accurately, quickly and in a number of different colours. Use a screen clipping tool to capture the shapes you create for pasting into notes or alternatively copy the shapes onto square spotty paper.

"Here's a challenge to 'Pick' at! Given a simple polygon constructed on the grid above, Pick's theorem provides a simple formula for calculating the area of this polygon in terms of the number I of lattice points in the interior located in the polygon and the number b of lattice points on the boundary placed on the polygon's perimeter. Can you figure out the formula?"
