This math assessment workbook provides students with extensive practice in subtracting decimals. They will practice solving straightforward vertical subtraction problems, such as 5.7 minus 1.3 and 0.7 minus 0.4. They also tackle money questions where a fixed cost in dimes is taken from a dollar amount. Word problems ask students to determine the faster time by subtracting tenths. Some items require students to translate language like "two tenths" or "four tenths" into decimal numerals before subtracting from whole numbers. Students will also practice taking a horizontal problem, such as "1 minus 0.1," and figure out how to solve it by setting it up vertically.
