We want a "Progressive Calculator" for K-12 education. The calculator would have a realistic look and feel. It can be physically expandable...perhaps like a "flip-phone." It would probably have 5 stages. Stage-1, for children in 1st grade. It would add, substract, multiply, and divide and that's it. Stage-2 would add simple memory and negative/positive numbers appropriate for children in grades 2 to 4. Stage-3 would add square root and perhaps a few other functions. Stage-4 would add multiple number systems, gemometry, and more functions for use with students in grades 7 and 8. Stage-5 would add trig and stat functions and possibly basic graphing capabilities. The idea behind this calculator is to extend the use of one Flash-based calculator throughout grades K to 12 by having the option to use it as a very elementary, elementary, more advanced, advanced, and very advanced math calculator. The typical Windows calculator has "standard" and "scientific" modes. The "Progressive Calculator" would have 5 modes that start "ultra-simple" for Kindergarten, and moves to highly complex for advanced high school math. The look and feel would be realistic, the ability to switch back and forth through the "stages" would be very easy, and of course, the accuracy of calculations would be accurate. The byte count swf needs to be as small as possible. The graphic needs to be small enough to fit on screen with other images, but easy to see when not zoomed. Perhaps, at each stage more buttons slide out. Perhaps at each stage the display window expands. The provider would have to figure out an innovative way to make the calculator "pump up" or "pump down" based on the grade level of the child using the calculator.
We need to see samples to verify you are up to the task of accomplishing this tool. You need to provide a creative design for making a calculator that looks good, is easy to use, and is understandable that it is made for multiple grade levels of school children. We will send interested providers 6 url links to calculators we have considered. None of them do exactly what we want to do. Each of them has a feature/s we like, but none of them has pulled everything together to make one calculator that all children can use across all grade levels.
