4th Grade STAAR Math Reference Sheet & Formula Chart

Official Texas TEA formulas for perimeter and area, alongside customary and metric conversion tables for Grade 4 Mathematics.

Perimeter & Area Formulas (TEKS 4.5D)

Official formulas provided on the Texas Grade 4 STAAR Mathematics reference sheet.

MeasurementShapeTEA Standard FormulaDefinition & Notes
PerimeterSquareP = 4sMultiply the side length s by 4.
RectangleP = 2l + 2w or P = 2(l + w)Double length plus double width.
AreaSquareA = s × sSide length multiplied by itself.
RectangleA = l × wLength multiplied by width.

Customary & Metric Conversions (TEKS 4.8A, 4.8B)

Official unit conversions provided on the Grade 4 reference materials chart.

Customary Conversions

Length

1 mile (mi) = 1,760 yards (yd) = 5,280 feet (ft)

1 yard (yd) = 3 feet (ft) = 36 inches (in.)

1 foot (ft) = 12 inches (in.)

Volume and Capacity

1 gallon (gal) = 4 quarts (qt)

1 quart (qt) = 2 pints (pt)

1 pint (pt) = 2 cups (c)

1 cup (c) = 8 fluid ounces (fl oz)

Weight and Mass

1 ton (T) = 2,000 pounds (lb)

1 pound (lb) = 16 ounces (oz)

Metric Conversions

Length

1 kilometer (km) = 1,000 meters (m)

1 meter (m) = 100 centimeters (cm) = 1,000 millimeters (mm)

1 centimeter (cm) = 10 millimeters (mm)

Volume and Capacity

1 liter (L) = 1,000 milliliters (mL)

Weight and Mass

1 kilogram (kg) = 1,000 grams (g)

1 gram (g) = 1,000 milligrams (mg)

Time Conversions

1 year = 12 months = 52 weeks = 365 days

1 week = 7 days • 1 day = 24 hours

1 hour = 60 minutes • 1 minute = 60 seconds

4th Grade STAAR Math Reference Sheet FAQs

Answers regarding formula chart usage, allowed testing rulers, and calculator rules for 4th graders.

What formulas are on the official 4th Grade STAAR Math reference chart?

The Texas Education Agency Grade 4 Mathematics Reference Materials sheet includes perimeter formulas for rectangles (P = 2l + 2w or P = 2(l + w)) and squares (P = 4s), and area formulas for rectangles (A = l × w) and squares (A = s × s). It also provides complete conversion tables for customary and metric units of length, capacity/volume, mass/weight, and time.

Are rulers provided on the 4th Grade STAAR Math exam?

Yes. Students are provided with both a customary ruler (marked in units of inches, half-inches, fourth-inches, and eighth-inches) and a metric ruler (marked in centimeters and millimeters). For online test administrations via Cambium, students can open and rotate digital on-screen rulers.

Can 4th graders use a calculator on the STAAR Math test?

No. Under TEA policy, calculators are not permitted for general education students on the Grade 4 STAAR Mathematics assessment. Students must demonstrate paper-and-pencil computation across all four operations, including multi-digit multiplication and division with remainders.

How do customary conversion tables help 4th graders on STAAR word problems?

Many TEKS 4.8B and 4.8C word problems require multi-step unit conversions—such as converting gallons to cups, or yards to inches. The reference chart provides official conversion factors, saving students memory load and preventing simple calculation errors.
