Ordering Decimals with Zero Digits is a family of tasks on decimals to help fifth graders understand if decimals with more zero digits are greater than those without zero digits. In the first example given, the zeros are in the hundredths and thousandths place values, and the decimals to be ordered have the same number in the tenths place. In the second example, the ones, tenths, and hundredths place values are the same, while the zeros lie in the thousandths and ten-thousandths place. Both examples provide multiple variations and extensions to enforce stronger critiques of the given responses and to contain argumentation language.

The task, Comparing Decimals, is created for fifth graders working on reading decimals and learning about place value of decimals. Students are asked to compare two decimals. The task offers two different variations: students are asked to either critique the correct answer or critique an incorrect answer. The incorrect response addresses a common error in which students believe a number to be larger based on the number of digits visible or based on larger digits after the decimal point. The task includes argumentation language including claim and warrants.
