Describe the minimally different sets that the text recommends presenting to students after introducing students to reading decimals representing tenths and hundredths. Include an example of an appropriate minimally different set
What will be an ideal response?
The minimally different sets for reading decimals that represent tenths and hundredths include three decimal numerals: a decimal representing tenths (.8) and two decimals representing hundredths. In one of these hundredth decimals, a zero would precede the numeral (.08), while in the other hundredth decimal, the zero would follow the numeral (.80). The purpose of these minimally different sets is to focus student attention on the number of digits following the decimal. An appropriate minimally different set would be .07, .70, .7 or .4, .04, .40.
