Grade 5 Math 2nd Semester Final Review 2025-2026

A comprehensive set of vocabulary and conceptual flashcards based on the 2nd Semester Final Review for Grade 5 Math, covering multiplication, division, measurement, volume, data, and geometry.

Unit Fraction

A fraction where the numerator is $1$, such as $\frac{1}{9}$, $\frac{1}{4}$, $\frac{1}{3}$, $\frac{1}{5}$, or $\frac{1}{2}$.

Mixed Number

A number consisting of a whole number combined with a fraction, such as $3 \frac{4}{5}$ or $7 \frac{1}{2}$.

Multiplication as Scaling

The process of resizing a quantity by a factor, represented in the study guide using the symbols $>$, $<$, and $=$.

Area of a Rectangle

The measure of the size of a rectangular surface, covered in Lesson 8-6.

Quotient

The result of a division expression, which can be represented as a fraction (e.g., $5 \div 9 = \frac{5}{9}$) or a mixed number (e.g., $7 \div 5 = 1 \frac{2}{5}$).

Line Plot

A graph used to analyze data frequencies, such as recording bowling shoe sizes, pearl sizes, or rock sample weights in ounces.

Rectangular Prism

A three-dimensional solid shape, such as a garage or a sand box, for which volume can be calculated.

Volume

The amount of space a solid occupies, modeled in Lesson 11-1 and calculated using formulas in Lesson 11-2.

Customary Units of Length

Units used to measure distance in the customary system, including inches ($in$), feet ($ft$), yards ($yd$), and miles ($mi$).

Customary Units of Capacity

Units used to measure liquid volume in the customary system, including fluid ounces ($fl\,oz$), cups ($c$), pints ($pt$), quarts ($qt$), and gallons ($gal$).

Customary Units of Weight

Units used to measure how heavy an object is in the customary system, including ounces ($oz$), pounds ($lb$), and tons ($T$).

Metric Units of Length

Units based on the meter used to measure distance, including millimeters ($mm$), centimeters ($cm$), meters ($m$), and kilometers ($km$).

Metric Units of Capacity

Units used to measure liquid volume in the metric system, specifically milliliters ($mL$) and liters ($L$).

Metric Units of Mass

Units used to measure matter in the metric system, including milligrams ($mg$), grams ($g$), and kilograms ($kg$).

Units of Time

Units used to measure duration, including seconds, minutes ($min$), and hours ($hr$).

Numerical Expression

A mathematical phrase containing numbers and operations, such as $15 - 1 + ( 6 \div 2)$.

Evaluate

To find the value of a numerical expression by performing the operations in the correct order.

Coordinate System

A system used to locate points on a grid using ordered pairs ($x, y$).

Ordered Pair

A pair of numbers used to identify a specific point on a coordinate grid, such as $(2, 1)$ or $(7, 6)$.

Numerical Pattern

A sequence of numbers that follows a specific rule, such as "add 15", "add 8", "add 6", or "add 2".

Quadrilateral

A four-sided polygon, including specific types such as trapezoids, parallelograms, rectangles, and squares.

Parallelogram

A quadrilateral that includes squares as special cases; however, not all trapezoids are parallelograms.
