All 12 Colorado math standards for 4th grade, each explained in plain English. The official wording is in Colorado Department of Education's document, linked at the end of this page.

12 standards

Number and Quantity

5 standards
MA.4.NBT.A
Explain that a digit is worth ten times as much one place to the left, read, write in expanded form, and compare multi-digit whole numbers, and round them to any place.
MA.4.NBT.B
Add and subtract multi-digit numbers with the standard method, multiply up to 4 digits by 1 digit and 2 digits by 2 digits, and divide 4-digit numbers by 1 digit with remainders.
MA.4.NF.A
Use fraction models to show why 2/3 = 8/12 and build equivalent fractions, and compare fractions with different tops and bottoms using common denominators or a benchmark like 1/2.
MA.4.NF.B
Split fractions into unit fractions, add and subtract fractions and mixed numbers with like denominators, and multiply a fraction by a whole number like 4 × 2/3, including in word problems.
MA.4.NF.C
Rewrite tenths as hundredths to add them, like 3/10 + 4/100 = 34/100, write such fractions as decimals like 0.34, and compare decimals to the hundredths using >, =, or <.

Algebra and Functions

3 standards
MA.4.OA.A
Read multiplication as a comparison, like 24 is 6 times as many as 4, solve comparison word problems by multiplying or dividing, and solve multistep problems, interpreting remainders.
MA.4.OA.B
Find all factor pairs of a number from 1 to 100, tell whether it is a multiple of a given one-digit number, and decide whether it is prime or composite.
MA.4.OA.C
Create number or shape patterns that follow a given rule, and spot features the rule never states, like add 4 starting at 2 giving only even numbers.

Data, Statistics, and Probability

3 standards
MA.4.MD.A
Convert larger units to smaller ones like hours to minutes, solve word problems on distance, time, volume, mass, and money, and use rectangle area and perimeter formulas.
MA.4.MD.B
Show measurements in halves, quarters, and eighths of a unit on a line plot, and use the plot to add and subtract fractions, like the gap between the tallest and shortest plant.
MA.4.MD.C
Explain angles as turns measured in degrees out of 360, measure and sketch angles with a protractor, and find unknown angles by adding or subtracting the parts of a larger angle.

Geometry

1 standard
MA.4.G.A
Draw and find lines, rays, right, acute, and obtuse angles, and parallel or perpendicular lines in shapes, sort shapes by them, pick out right triangles, and draw lines of symmetry.
