At Math Central we use the term "math beyond school". Go to the Quandaries and Queries page on Math Central and use the Quick Search to search for the term math beyond school decimals. Now try math beyond school fractions and finally math beyond school percent. If you need more yo can go to the Math Beyond School section of Math Central and use the Search to search for the terms decimals, fractions and percent. Penny
