Question Corner and Discussion Area

When showing students how to add, subtract, multiply or divide decimals, I I find it very useful to ask students to convert the decimals into fractional forms so they will see a connection to fractions, to money, to basic geometry. For example: 0.35 + 0.15 = 35/100 + 15/100 = 50/100 = 0.50 which equals 50 cents in the context of dollars, or 1/2 the area of a unit square in the context of geometry.Have any of you wonderful educators ever used this logic? If yes, what have your results been?

In great need for feedback, Blanche
