Common Core standards

Report cards and homework sometimes list a code like 2.NBT.B.5. The first part is the grade. Find your code below, or search for it.

• 1.NBT.C.4 Add within 100 using models, drawings, and place value strategies, including when you need to make a new ten.
• 1.OA.C.6 Add and subtract within 20 (fluently within 10) using strategies like counting on, making ten, and doubles.
• 2.MD.B.6 Show whole numbers, sums, and differences within 100 on a number line.
• 2.NBT.B.5 Add and subtract within 100 quickly and accurately, using place value strategies.
• 2.NBT.B.7 Add and subtract within 1000 using models, drawings, and place value strategies, including trading tens and hundreds (regrouping).
• 3.G.A.1 Understand that shapes in different groups can share features, and that rhombuses, rectangles, and squares are all quadrilaterals.
• 3.MD.C.7c Use area models to show why multiplication can be split up: a × (b + c) = a × b + a × c.
• 3.NBT.A.1 Round whole numbers to the nearest 10 or 100.
• 4.MD.A.1 Know how big measurement units are compared to each other (1 foot = 12 inches, 1 kilometer = 1000 meters) and convert larger units to smaller ones.
• 4.MD.B.4 Make a line plot of measurements in halves, quarters, and eighths, and use it to solve problems.
• 4.NBT.A.1 Understand that each place in a number is worth ten times the place to its right (700 is ten times 70).
• 4.NBT.A.3 Round multi-digit whole numbers to any place.
• 4.NBT.B.5 Multiply up to a four-digit number by a one-digit number, and two two-digit numbers, using place value strategies like area models.
• 4.NBT.B.6 Divide up to four-digit numbers by one-digit numbers, with remainders, using place value strategies like area models.
• 4.NF.B.4c Solve word problems that multiply a fraction by a whole number.
• 4.NF.C.6 Write fractions with denominators of 10 or 100 as decimals (62/100 = 0.62).
• 5.G.A.1 Understand a coordinate grid: two number lines that cross at zero, and points named by (x, y) pairs.
• 5.G.A.2 Graph points in the first quadrant of a coordinate grid to solve problems, and explain what the coordinates mean.
• 5.G.B.3 Understand that features of a group of shapes belong to every shape in that group (every square is a rectangle, so it has four right angles).
• 5.G.B.4 Sort two-dimensional shapes into a family tree based on their properties.
• 5.MD.A.1 Convert between units in the same measurement system (5 cm = 0.05 m) and use this in multi-step problems.
• 5.MD.B.2 Make a line plot of measurements in halves, quarters, and eighths, and use fraction math to solve problems with it.
• 5.MD.C.3 Understand volume as the amount of space a solid takes up.
• 5.MD.C.4 Measure volume by counting unit cubes (cubic centimeters, cubic inches, cubic feet, and so on).
• 5.MD.C.5 Connect volume to multiplication and addition, and solve volume problems.
• 5.NBT.A.1 Understand that each place in a number is worth 10 times the place to its right and 1/10 of the place to its left.
• 5.NBT.A.2 Explain patterns when multiplying or dividing by 10, 100, or 1000 (zeros and decimal point moves), and use exponents for powers of 10.
• 5.NBT.A.3 Read, write, and compare decimals to thousandths.
• 5.NBT.A.4 Round decimals to any place.
• 5.NBT.B.5 Multiply multi-digit whole numbers quickly using the standard method.
• 5.NBT.B.6 Divide up to four-digit numbers by two-digit numbers using place value strategies like area models.
• 5.NBT.B.7 Add, subtract, multiply, and divide decimals to hundredths using models and place value strategies.
• 5.NF.A.1 Add and subtract fractions (and mixed numbers) with different denominators by rewriting them with a common denominator.
• 5.NF.A.2 Solve word problems that add and subtract fractions, and estimate to check if answers make sense.
• 5.NF.B.3 Understand a fraction as division (3/4 = 3 ÷ 4), and solve sharing problems with fraction answers.
• 5.NF.B.4a Understand 2/3 × 4 as splitting 4 into 3 equal parts and taking 2 of them.
• 5.NF.B.5 Understand multiplying as resizing (scaling).
• 5.NF.B.5a Compare the size of a product to one of its factors without multiplying.
• 5.NF.B.5b Explain why multiplying by a fraction greater than 1 makes a number bigger, and by a fraction less than 1 makes it smaller.
• 5.NF.B.6 Solve real-world problems that multiply fractions and mixed numbers.
• 5.NF.B.7 Divide unit fractions by whole numbers and whole numbers by unit fractions.
• 5.NF.B.7a Divide a unit fraction by a whole number (1/3 ÷ 4) and explain with a picture.
• 5.NF.B.7b Divide a whole number by a unit fraction (4 ÷ 1/5) and explain with a picture.
• 5.NF.B.7c Solve word problems that divide unit fractions and whole numbers.
• 5.OA.A.1 Use parentheses and brackets in math expressions and work them out in the right order.
• 5.OA.A.2 Write simple expressions for calculations, and understand expressions without solving them (3 × (18 + 9) is three times 18 + 9).
• 5.OA.B.3 Make two number patterns from two rules, compare them, and graph the pairs on a coordinate grid.
• K.OA.A.3 Break numbers up to 10 into two parts in more than one way (5 = 2 + 3 and 5 = 4 + 1).
• K.OA.A.4 For any number from 1 to 9, find the number that adds to it to make 10.
