Challenge 5th Graders With Fast-Paced Subtraction Practice

Subtraction at this level is mostly about signs and context — negative results, differences inside multi-step expressions, and subtraction of decimals and fractions. Students who are still reconstructing basic differences spend their attention there instead of on the structure of the problem, which is why speed on the plain facts keeps paying off.

Fifth grade moves from whole numbers to the rest of the number system: fractions with unlike denominators, decimals, percentages, and order of operations. Percentages are where arithmetic becomes visibly useful outside school, and the students who cope best are the ones whose basic facts are automatic enough to leave attention for the new structure.

5th graders are expected to subtract decimals and unlike fractions without losing place value; after that comes subtracting decimals and unlike fractions.

Watch for forgetting to fill trailing zeros before subtracting decimals of different lengths.
