37 standards
Number Sense and Operations in Base Ten
7 standards4.NBT.A.1
Round whole numbers up to one million to any place, like 46,382 to the nearest thousand is 46,000.
4.NBT.A.2
Say, write and recognize whole numbers up to one million in words, digits and expanded form, like 52,307 = 50,000 + 2,000 + 300 + 7.
4.NBT.A.3
Compare two large whole numbers with >, = or < and explain why the comparison is true, like 45,210 > 45,120.
4.NBT.A.4
Recognize that a digit is worth ten times as much as the same digit one place to its right, like the 7 in 700 compared with 70.
4.NBT.A.5
Add and subtract whole numbers up to one million quickly and accurately.
4.NBT.A.6
Multiply numbers of up to four digits by one-digit numbers and two-digit by two-digit numbers, like 23 × 47, and explain the answer.
4.NBT.A.7
Divide numbers of up to four digits by a one-digit number to find the quotient and remainder, like 1,234 ÷ 5 = 246 R4, and explain the answer.
Number Sense and Operations in Fractions
12 standards4.NF.A.1
Explain, show with a drawing, or both, why two fractions name the same amount, like 1/2 and 3/6.
4.NF.A.2
Spot fractions that name the same amount and create new equal ones, like 2/3 = 4/6 = 8/12.
4.NF.A.3
Compare two fractions with >, = or < and explain how you know, like 3/4 > 5/8.
4.NF.B.4
Explain adding fractions as joining parts of one whole and subtracting as taking parts away, like 2/8 + 3/8 = 5/8.
4.NF.B.5
Split a fraction into a sum of smaller fractions with the same denominator, writing and explaining an equation for each, like 3/8 = 1/8 + 2/8.
4.NF.B.6
Solve problems that add and subtract fractions and mixed numbers with the same denominator, like 2 1/4 + 1 3/4 = 4.
4.NF.B.8
Solve problems that multiply a fraction by a whole number, like 3 × 2/5 = 6/5.
4.NF.C.9
Write fractions with a denominator of 10 or 100 as decimals, like 62/100 = 0.62.
4.NF.C.10
Recognize that a fraction and a decimal can name the same amount, like 3/10 and 0.3.
4.NF.C.11
Read decimals to the hundredths aloud, write them in digits, words and expanded form, and recognize each form, like 4.07 = 4 + 0.07.
4.NF.C.12
Compare two decimals to the hundredths with >, = or < and explain the comparison, like 0.45 < 0.5.
Relationships and Algebraic Thinking
7 standards4.RA.A.1
Multiply or divide to solve comparison problems, like a red ribbon that is 4 times as long as a 6-inch blue one.
4.RA.A.2
Solve whole number problems with several steps using all four operations and a letter for the unknown, then estimate to check the answer is reasonable.
4.RA.A.3
Solve division problems with a letter for the unknown and decide what the remainder means, like needing 4 vans for 26 students at 8 per van, and explain why.
4.RA.B.4
See that a number is a multiple of every one of its factors, like 12 is a multiple of 3, and list the multiples of a given number.
4.RA.B.5
Find all factor pairs of a whole number up to 100 and decide if it is prime or composite, like 7 is prime and 15 is composite.
4.RA.C.6
Create a number pattern from a given rule, like start at 3 and add 4 to get 3, 7, 11, 15.
4.RA.C.7
Describe the rule of a given pattern in words or with math symbols, like add 5 each time or n + 5.
Geometry and Measurement
8 standards4.GM.A.1
Draw and recognize the basic parts of geometric figures, like points, lines, segments, rays, angles, and perpendicular and parallel lines.
4.GM.A.2
Sort flat shapes into groups by their sides, their angles or both, like grouping every shape that has a right angle.
4.GM.A.3
Draw the lines of symmetry for a flat figure, like the four lines that fold a square into matching halves.
4.GM.B.4
Identify angles and estimate how many degrees they measure, like judging that an angle is a bit less than 90 degrees.
4.GM.B.5
Use a protractor to draw and measure angles to the nearest whole degree, like drawing a 65 degree angle.
4.GM.C.6
Know how units in one system compare in size and express a larger unit in smaller ones, like 3 feet = 36 inches or 2 hours = 120 minutes.
4.GM.C.7
Use all four operations to solve problems about distance, elapsed time, liquid volume, weight and money, like finding the change from $20.
4.GM.C.8
Find a rectangle's area or perimeter with A = l × w and P = 2l + 2w in real problems, like finding the length of a 48-square-foot room that is 6 feet wide.
Data and Statistics
3 standards4.DS.A.1
Make a frequency table, a line plot or both to show measurement data, like the lengths of the pencils in a classroom.
4.DS.A.2
Use information in a table or graph to solve addition and subtraction problems, like how many more students chose soccer than tennis.
4.DS.A.3
Interpret data shown in bar graphs, picture graphs, line plots and frequency tables, like finding which value appears most often.
