Following the content of the standard school curriculum, this book presents in 418 problems and diversions the basic ideas of arithmetic. Averages, fractions, decimals, percent, powers and roots, etc. Shortcuts, checking methods, also introduced in this enjoyable format. 120 illustrations.
This is an outstanding book that I have used in my classes for years and years. It has a wealth of material that is of a quality far above the usual compendiums of games that you usually see. Great games, challenges, tricks, etc. that you will love using with your students, and the range is from early grades on up to at least junior high and sometimes beyond.
Great stuff. While you're at it, buy an extra copy or two for your colleagues; this is one book you're going to love and use often.
