Help with Arithmetic

Sometimes students don't have access to new computers that have all the latest support for powerful computer software. So I'd like to write some simple, but useful, software which will run on older computers that may not have connections to the internet and which don't have any recent supporting software on them.

With this in mind, I've started work on a program called Herbi Numbers. The Herbi Numbers program is all held in a single computer file, with no installation program. You can simply copy the program from this web site to anywhere on your computer, and run it. You can even run it from a USB stick that's connected to your computer.

To get the program, click get the Herbi Numbers program, and then say Save when prompted. You can then save it anywhere on your computer and run it from wherever you saved it. If you save it to your computer's desktop, then the following image will appear after you've saved the file:

When you run the Herbi Numbers, a window will appear that fills the screen. You might not be able to see all the contents of the window if your computer has a very small screen.

This first version of Herbi Numbers only uses addition, and the sum of the numbers shown will always be a single number from 2 to 9.

The goal is for your student to type the sum of the two numbers. So if in the above example, the student types '8', Herbi smiles.

Herbi smiles for four seconds, and then another sets of numbers are shown. For example:

If the student types an incorrect answer, then the incorrect answer will be shown for two seconds before being removed. Herbi does not change during this time. When an incorrect answer is typed, a collection of items will appear to help the student work out the correct answer. For example, if the student types '8' in the above example:

Once the students types the correct answer, the items are cleared and Herbi smiles. The items that can appear are apples, oranges, pears, and watermelon slices. For example:

At any time you can press the space bar to move on to another question.

If you feel that Herbi Numbers has potential to be useful to your students, let me know how you'd like it to evolve! Perhaps the most useful change would be to incorporate other types of arithmetic such as subtraction or division. Or maybe you'd like other items to be shown, such as different types of vehicles.

I'll look forward to hearing your thoughts on the future of Herbi Numbers!
