Grade 5 math practice
Grade 5 adds decimals, follows the order of operations, and finds a missing angle in a triangle. Powers of two are the exponent exercises in the catalog, and percent of a number sits beside the fractions lesson from earlier grades.
Fractions and area are shared with grade 4. Order of operations, angles, powers of two, and percents continue into later grades. This page links each lesson once.
Topics
Fractions — Name equal parts, build equivalent fractions, and add fractions that share a denominator.
Order of operations — Do the work inside parentheses first, then multiply and divide before you add and subtract.
Decimals — Compare decimals by place value, then add them by lining up the decimal point.
Area and perimeter — Find the area and the perimeter of a rectangle from its length and width.
Angles — Find the missing angle in a triangle when the other two angles are known.
Powers of two — Evaluate a power of two by multiplying that many factors of 2.
Percentages — Find a percent of a number, then describe a price change as a percent increase.
Sample exercises
Order of operations Simplify an expression by doing parentheses, then multiplication and division.
Add related fractions Add fractions whose denominators are related, such as fourths and eighths.
Mean Find the mean of a short list of numbers.
