28 standards
Operations and Algebraic Thinking
5 standardsKY.4.OA.1
See a multiplication equation as a comparison, like 24 = 3 × 8 meaning 24 is 3 times as many as 8, and write equations for such statements.
KY.4.OA.2
Multiply or divide to solve comparison word problems, like a rope 4 times as long, using drawings and equations, and tell times-as-many apart from more-than problems.
KY.4.OA.3
Use the order of operations, and solve multistep whole-number word problems with letter equations, making sense of remainders and checking answers by estimating.
KY.4.OA.4
Find all factor pairs for numbers 1 to 100, see that a number is a multiple of each factor, check multiples of one-digit numbers, and tell prime from composite.
KY.4.OA.5
Make a number or shape pattern from a rule and notice features the rule does not state, like add 3 starting at 1 giving odd and even numbers in turn.
Number and Operations in Base Ten
6 standardsKY.4.NBT.1
Explain that each digit in a whole number is worth ten times what it would be one place to the right, like 700 is ten times 70.
KY.4.NBT.2
Read and write large whole numbers as numerals, in words, and in expanded form, and compare two of them by place value using >, =, and <.
KY.4.NBT.4
Add and subtract multi-digit whole numbers quickly and accurately using a standard written method.
KY.4.NBT.5
Multiply up to a four-digit number by a one-digit number and two two-digit numbers using place value and properties, and explain it with equations, arrays, or area models.
KY.4.NBT.6
Divide numbers of up to four digits by one digit, finding quotients and remainders with place value, properties, or multiplication facts, shown with arrays or area models.
Number and Operations – Fractions
7 standardsKY.4.NF.1
Use fraction models to find equal fractions with different numbers, like 2/3 = 4/6, and explain why multiplying top and bottom by the same number keeps the value.
KY.4.NF.2
Compare fractions with different numerators and denominators using <, =, or >, checking that both refer to the same whole, and justify the answer.
KY.4.NF.5
Rewrite tenths as hundredths, like 3/10 = 30/100, and add a fraction in tenths to one in hundredths.
KY.4.NF.6
Write fractions with denominators of 10 or 100 as decimals, like 62/100 as 0.62.
KY.4.NF.7
Compare decimals to hundredths by thinking about their size, checking they refer to the same whole, and record the result with >, =, or < and explain it.
Measurement and Data
7 standardsKY.4.MD.1
Know how units compare in size within one system, like kilometers and meters or hours and minutes, write large units as small ones, and list them in a two-column table.
KY.4.MD.2
Solve word problems on distance, time, volume, mass, and money with whole numbers, simple fractions, or decimals, converting to smaller units and using number line scales.
KY.4.MD.3
Use the area and perimeter formulas for rectangles to solve real-life and math problems, like finding a garden's width from its area and length.
KY.4.MD.4
Ask a question about number data, make a dot plot of measurements in halves, fourths, and eighths, and use it to add and subtract fractions to solve problems.
KY.4.MD.7
Explain that an angle split into parts measures the sum of the parts, and add or subtract to find unknown angles in diagrams and real-life problems.
Geometry
3 standardsKY.4.G.1
Draw points, lines, segments, rays, angles, and perpendicular and parallel lines.
KY.4.G.2
Sort flat shapes by whether they have parallel or perpendicular lines or angles of a certain size, and recognize and identify right triangles as their own group.
KY.4.G.3
Recognize a line of symmetry in a flat shape, identify shapes that fold into matching halves, and draw their lines of symmetry.
