Summary: I use this mostly for multiplication drills for my children. You have the option of doing drills by family. If you get a wrong answer a 'X' mark will show at the top right of the screen. When the answer is correct a check mark will show. Then it goes on to the next problem in the multiplication family that you choose to do. Great for school or for review of facts.
Summary: My 1st grade math whiz loves this calculator and that he can use it for all sorts of calculations (he likes to see what # x # would be for example) and can use it like 'flash cards'. Easy to use for his age.
Summary: My son loves calculators but has poor short term memory. So learning his facts was a challenge. I purchased several different tools and I am safe to say that this was his favorite one. It has several different functions and is easy to use.
Summary: I bought these for my entire third grade class. I love using them for facts practice before our lesson each day. The kids love them because they are easy to use, and show their scores. Great little practice fact calculator. Hard to find in stores too.
