See N Solve Visual Calculator Class Pack
This brightly-colored calculator with its over-sized LCD screen is the perfect child-friendly tool for reinforcing basic math skills. The simple four-function calculator sets up the problem exactly as young students are taught to write it out. As they carry out addition, subtraction, multiplication and division problems, the display window shows the entire problem, not just the last number entered. A great way to introduce elementary school children to using calculators for more difficult problem-solving. Requires 2 AA batteries (not included).
