Missouri 6th Grade Math Standards

All 29 Missouri math standards for 6th grade, each explained in plain English. The official wording is in Missouri Department of Elementary and Secondary Education's document, linked at the end of this page.

29 standards

Ratios and Proportional Relationships

3 standards
6.RP.A.1
Describe a ratio as a comparison of two amounts and show it in different ways, like 3 to 2, 3:2 or 3/2 for cats to dogs.
6.RP.A.2
Explain what the unit rate of a ratio means, like 12 miles in 3 hours is 4 miles per hour.
6.RP.A.3
Solve ratio and rate problems with tables of equal ratios and graphs, unit rates, percents, and unit conversions within and between measurement systems.

Number Sense and Operations

8 standards
6.NS.A.1
Divide fractions by fractions, explain what the answer means, and use it to solve problems, like how many 3/4-cup servings are in 2/3 of a cup.
6.NS.B.2
Divide whole numbers with many digits quickly and accurately, like 7,452 ÷ 36 = 207.
6.NS.B.3
Add, subtract, multiply and divide decimals quickly and accurately, like 4.6 × 0.35 or 9.12 ÷ 0.4.
6.NS.B.4
Find the greatest common factor and least common multiple of two numbers, and use the distributive property to factor a sum, like 24 + 36 = 12 × 5.
6.NS.C.5
Show real amounts with signed numbers, like a temperature of −5 degrees, a 300-foot dive as −300, or a $20 deposit as +20.
6.NS.C.6
Place rational numbers on horizontal and vertical number lines, put them in order in problems, and see that a number and its opposite sit on either side of zero.
6.NS.C.7
Explain absolute value as how far a number is from 0 on the number line, like −6 and 6 both have an absolute value of 6.
6.NS.C.8
Switch rational numbers between fractions, decimals and percents, using terminating decimals and the fractions 1/3 and 2/3, like 3/8 = 0.375 = 37.5%.

Expressions, Equations and Inequalities

9 standards
6.EEI.A.1
Explain how an expression differs from an equation, like 3x + 2 has no equals sign while 3x + 2 = 11 does.
6.EEI.A.2
Build and find the value of expressions with letters and whole-number powers, name their parts, and explain what each letter stands for, like 2x³ when x = 3.
6.EEI.A.3
Use properties of operations to recognize and write expressions that are equal, like 3x + 6 is the same as 3 times the sum of x and 2.
6.EEI.B.4
Test numbers from a given set in an equation or inequality to see which make it true, like checking whether 4 solves x + 7 > 10.
6.EEI.B.5
Explain that solving an equation or inequality means finding the values, if any, that make it true, like x = 5 for x + 3 = 8.
6.EEI.B.6
Write and solve equations with a letter for an unknown amount in a real situation and explain what the letter means, like p + 12 = 30 for points still needed.
6.EEI.B.7
Solve one-step equations with one unknown using whole numbers, fractions and decimals that are not negative, like 0.5x = 3.5 or x + 2/3 = 4.
6.EEI.B.8
Write inequalities like x > 5 or x ≤ 12 for a condition, graph their solutions on a number line, and see that they can have endless solutions.
6.EEI.C.9
Describe how two changing quantities relate by writing an equation for the dependent one and linking it to tables and graphs, like d = 60t for distance and time.

Geometry and Measurement

4 standards
6.GM.A.1
Find the area of polygons by splitting them into or building them from rectangles and triangles, like an L-shaped room or a trapezoid.
6.GM.A.2
Find how much a box-shaped prism holds by filling it with layers of its base and with V = l × w × h or V = Bh, like 2 × 3 × 4 = 24 cubic units.
6.GM.A.3
Solve problems by plotting points in all four quadrants, using signs to tell the quadrant, reflections across the axes, distances along a grid line, and drawing polygons.
6.GM.A.4
Draw nets of rectangles and triangles for solid figures and use them to find surface area, like the six faces of a cereal box.

Data Analysis, Statistics and Probability

5 standards
6.DSP.A.1
Tell a statistical question from others by whether its answers are expected to vary, like how tall are the students in my class.
6.DSP.A.2
Describe a set of data by its center, its spread and its overall shape.
Common Core 6.SP.2
6.DSP.A.3
Explain that a measure of center sums up a data set with one number, while a measure of variation shows how spread out the values are.
6.DSP.B.4
Show and interpret numerical data with dot plots, histograms and box plots, and make and read circle graphs.
6.DSP.B.5
Summarize data in context by giving the count, what was measured and in what units, center and spread, any patterns or unusual values, and why those measures fit.
