Suggested uses...

On an interactive whiteboard
As an alternative to a conventional hundreds board, set up or change a pattern quickly as you teach. Set up a second overlapping pattern so you can for example explore common multiples.

On your PC or laptop: configurable black line masters
Create printable task sheets with whatever patterns you wish and add your own instructions or questions for students.

How to use
There's no help system in place at this stage, but here's how to use the current version.

By default, the board displays numbers from 1 to 100.
1. Click the "Tools" button to reveal (or hide) the tools panel.
2. If you wish, change the range of numbers by using the top slider.
3. Select one of the two shadings - yellow fill or red outline.
4. Drag the bottom slider to set your multiple of choice.
5. If you wish, select the other shading, and set up a second set of multiples.
6. The "Clear" button below a shading clears that shading. "Clear all" clears both.

You can also set up any other patterns as follows...
• Toggle any single number on or off, by clicking on it.
• Click and drag through a range of squares to change the highlight to on / off.

Other features...
• The "Task input" button opens a panel allowing you to type in text to appear below a printed version of the hundreds board. This might be questions, instructions or whatever meets your needs.
• The "Print" button prints the current hundred's board with any instructions you entered using "Task input".
• The small double pointing arrow button at the lower edge, will switch the tools panel between the left and right sides of the board. This is with electronic smart board use in mind - you might find it more convenient to have the tools on the other side.
