Just a quick note of appreciation. I'm using your software for a student I teach who has many learning difficulties, but he is thrilled (and motivated) to be working with your software. Please continue the excellent work, and best of luck going forward.
Ed, Canada.

We are a homeschool family and we have been using your site for nearly 10 months now...we think you're great!

Keep up the fantastic work you do!
Warmest Regards
Sarah, New Zealand

I have been using your programs for years now and am really glad for a chance to say how FAB they are. They are better than any other I've found for educational purposes and a fraction of the price. All the kids who have used them at my school LOVE them and I think you are a very very clever man!!

Goopla - Number bonds
Colours and size of screenshot reduced to fit page

Suitable for UK Key Stage 1, 2, 3, 4 & 5 - USA 1st to 12th Grade (Age 5 - adult)





Recommended Minimum System: Pentium PC, Windows 95 or better e.g. XP, Vista, 32MB Ram.

Number bonds are about creating a mental image of how a number is made up, usually by adding two numbers together or subtracting one number from another.

On the first screen you are able to choose the number bond game to play from a drop down list, with numbers from 10 to 100 in tens. Once you have chosen, then click on the Play Addition or Play Subtraction button to play adding or subtracting number bonds.

In the game you have chosen you are presented with a Hoopla game of pegs with different values above them. At the top of the screen you are shown a sum or problem with a missing number. Using your mouse, click on the number peg that you believe is the answer. For example 5 + ? = 10, the answer is the number 5, so you would click on the 5 peg. Your mouse pointer will turn into a hand when over any peg on the board.

In the top left hand corner of each screen is a Menu button with three options.

Full Screen: Clicking this sets the program to full screen. Click on this button again to return to windowed mode.
Sounds: By default this is ticked (checked). To stop the sounds from playing, untick (uncheck) this option

Thanks for the TERRIFIC software at a great price!
Suzanne, USA

I've been a happy Olltwit user for years - I downloaded several of your programs back in '04, for my older son to use. Now it's time for my younger son to use them, and I've come back to your site to find 1) I owe you, and 2) you have more great stuff. I'm happy to pay up because I know the quality of your programs.
Mary Beth, Indiana, USA
