27 standards

Operations and Algebraic Thinking

5 standards
4.OA.1
Read a multiplication equation as a comparison, like 35 is 5 times as many as 7.
Common Core 4.OA.1
4.OA.2
Multiply or divide to solve times-as-many word problems, like a rope 3 times as long, using drawings and equations, and tell them apart from how-many-more problems.
4.OA.3
Solve multi-step word problems with all four operations, including what to do with remainders.
Common Core 4.OA.3
4.OA.4
Find the factor pairs of numbers 1 to 100 and tell prime numbers from composite ones.
Common Core 4.OA.4
4.OA.5
Make and extend number and shape patterns that follow a rule.
Common Core 4.OA.5

Number and Operations in Base Ten

6 standards
4.NBT.1
Recognize that a digit is worth ten times what it would be one place to the right, like the 7 in 700 versus 70, using place value, multiplication, or division.
4.NBT.2
Read and write whole numbers up to 1,000,000 in standard, word, and expanded form, and compare two of them by place value using >, =, and <.
4.NBT.3
Round whole numbers to any place up to 1,000,000 using place value, like 346,812 to the nearest ten thousand is 350,000.
4.NBT.4
Add and subtract whole numbers with many digits quickly and accurately using a standard written method, like stacking and regrouping.
4.NBT.5
Multiply up to four digits by one digit, and two two-digit numbers, with place-value strategies.
Common Core 4.NBT.5
4.NBT.6
Divide up to four digits by one digit, with or without remainders.
Common Core 4.NBT.6

Number and Operations—Fractions

7 standards
4.NF.1
Explain why two fractions are equivalent, using models.
Common Core 4.NF.1
4.NF.2
Compare fractions with different numerators and denominators.
Common Core 4.NF.2
4.NF.3
Add and subtract fractions and mixed numbers with like denominators.
Common Core 4.NF.3
4.NF.4
Multiply a fraction by a whole number.
Common Core 4.NF.4
4.NF.5
Rewrite tenths as hundredths, like 3/10 as 30/100, and use this to add tenths and hundredths, like 3/10 + 4/100 = 34/100.
4.NF.6
Write fractions with a denominator of 10 or 100 as decimals.
Common Core 4.NF.6
4.NF.7
Compare two decimals to hundredths.
Common Core 4.NF.7

Measurement and Data

7 standards
4.MD.1
Know how metric units of length, mass, and volume compare, convert a larger unit to a smaller one, like 4 meters is 400 centimeters, and list them in a two-column table.
4.MD.2
Solve real-world problems with money in decimals, elapsed time in hours and minutes, and metric distances, volumes, and masses, using models, clocks, and number lines.
4.MD.3
Use efficient strategies to find the area and perimeter of rectangles in real-world and math problems, like finding a missing side from the area and one side.
4.MD.4
Make and read picture graphs, bar graphs, and line plots, and use the data to solve problems with fourth grade numbers and operations.
4.MD.5
Understand angles and how they are measured in degrees.
Common Core 4.MD.5
4.MD.6
Measure and draw angles with a protractor.
Common Core 4.MD.6
4.MD.7
Add and subtract angle measures to find an unknown angle.
Common Core 4.MD.7

Geometry

2 standards
4.G.1
Draw points, lines, segments, rays, right, acute, and obtuse angles, and parallel and perpendicular lines, and find each of them in flat shapes.
4.G.2
Sort flat shapes by whether they have parallel or perpendicular lines or angles of a given size, like right angles.
