29 standards

Operations and Algebraic Thinking

6 standards
M.4.OA.A.1
Treat a multiplication equation as a comparison, like reading 35 = 5 x 7 as 35 being 5 times the size of 7, and turn comparison sentences into equations.
M.4.OA.A.2
Multiply or divide to solve times-as-many word problems with drawings and equations, and tell them apart from how-many-more problems.
M.4.OA.A.3
Solve multi-step whole-number word problems with all four operations, deciding what a remainder means, writing equations with a letter and checking by estimating.
M.4.OA.B.4
Find the factor pairs of numbers 1 to 100 and tell prime numbers from composite ones.
Common Core 4.OA.4
M.4.OA.C.5
Make and extend number and shape patterns that follow a rule.
Common Core 4.OA.5
M.4.OA.D.6
Multiply and divide within 100 flexibly, like finding 7 x 6 as 5 sixes plus 2 sixes, or using 8 x 5 = 40 to know 40 ÷ 5 = 8.

Number and Operations in Base Ten

6 standards
M.4.NBT.A.1
Know that a digit is worth ten times as much as the same digit one place to its right.
Common Core 4.NBT.1
M.4.NBT.A.2
Read and write multi-digit whole numbers in digits, words and expanded form, and compare two of them by place value using >, = and <.
M.4.NBT.A.3
Estimate answers to real problems with multi-digit whole numbers using mental math, friendly numbers or rounding, and judge how precise the estimate must be.
M.4.NBT.B.4
Add and subtract multi-digit whole numbers flexibly, with strategies or a written method based on place value and how the two operations relate.
M.4.NBT.B.5
Multiply up to a four-digit number by a one-digit number, and two two-digit numbers, with place value strategies shown in equations, arrays or area models.
M.4.NBT.B.6
Divide up to four-digit numbers by one-digit numbers, finding quotients and remainders with place value strategies shown in equations, arrays or area models.

Number and Operations—Fractions

7 standards
M.4.NF.A.1
Explain with tape diagrams or number lines why two fractions are equal even though their parts differ, and use a general rule to make equal fractions.
M.4.NF.A.2
Compare fractions with different tops and bottoms using benchmarks like 1/2, common denominators or numerators, and models, recording with >, = or <.
M.4.NF.B.3
Add and subtract fractions and mixed numbers with like or related denominators, like 1/2 + 1/4, break fractions into unit fractions, and solve word problems.
M.4.NF.B.4
Multiply a whole number by a fraction, like 3 x 2/5 as 3 groups of 2/5 or 6/5, using models, and solve word problems with a sensible answer range.
M.4.NF.C.5
Rewrite tenths as hundredths to add them, like 3/10 + 4/100.
Common Core 4.NF.5
M.4.NF.C.6
Write fractions with denominators of 10 or 100 as decimals, like 0.62 = 62/100, tie them to real measures and show them on a number line or grid.
M.4.NF.C.7
Compare decimals to hundredths by size and benchmarks, check that they refer to the same whole, and explain the result with models and >, = or <.

Measurement and Data

7 standards
M.4.MD.A.1
Know the relative sizes of units in one system, like kilometers and meters.
Common Core 4.MD.1
M.4.MD.A.2
Solve word problems about distance, time, liquid volume, mass and money, including simple fractions, decimals and changing to smaller units, using number line diagrams.
M.4.MD.A.3
Use the area and perimeter formulas for rectangles.
Common Core 4.MD.3
M.4.MD.B.4
Make a line plot with fractions of a unit and use it to solve problems.
Common Core 4.MD.4
M.4.MD.C.5
Understand angles and how they are measured in degrees.
Common Core 4.MD.5
M.4.MD.C.6
Measure and draw angles with a protractor.
Common Core 4.MD.6
M.4.MD.C.7
Add and subtract angle measures to find an unknown angle.
Common Core 4.MD.7

Geometry

3 standards
M.4.G.A.1
Draw points, lines, segments, rays, angles, and perpendicular and parallel lines.
Common Core 4.G.1
M.4.G.A.2
Sort 2D shapes by their parallel or perpendicular lines and by their angles.
Common Core 4.G.2
M.4.G.A.3
Find and draw lines of symmetry.
Common Core 4.G.3
