26 standards
Operations and Algebraic Thinking
4 standardsKY.2.OA.1
Solve one- and two-step word problems within 100 about adding to, taking from, combining, separating, and comparing, with the unknown anywhere, using drawings and equations.
KY.2.OA.2
Add and subtract numbers within 20 quickly and accurately in their heads, using mental math strategies like making ten.
KY.2.OA.3
Decide whether a group of up to 20 objects is odd or even, and write an even number as a doubles sum, like 12 = 6 + 6.
KY.2.OA.4
Find the total in an array of up to 5 rows and 5 columns by adding equal rows, like 3 + 3 + 3 + 3 = 12.
Number and Operations in Base Ten
9 standardsKY.2.NBT.1
Explain that a three-digit number is made of hundreds, tens, and ones, including that 100 is ten tens and 400 means four hundreds with no tens or ones.
KY.2.NBT.2
Count up and down within 1000 and skip-count by 5s, 10s, and 100s, like 250, 255, 260.
KY.2.NBT.3
Read and write numbers to 1000 as digits, in words, and in expanded form, like 426 as 400 + 20 + 6.
KY.2.NBT.4
Compare two three-digit numbers by their hundreds, tens and ones, and record the answer with >, = or <.
KY.2.NBT.5
Add and subtract within 100 quickly and accurately, using place value and the link between addition and subtraction.
KY.2.NBT.6
Add up to four two-digit numbers at once, like 23 + 45 + 12 + 30, by grouping tens and ones.
KY.2.NBT.7
Add and subtract within 1000 with models, place value, properties, and related facts, tying them to equations and explaining when to regroup tens or hundreds.
KY.2.NBT.8
Add or subtract 10 or 100 in their head from any number between 100 and 900, like 540 + 100 = 640.
KY.2.NBT.9
Explain why an adding or subtracting strategy works, not just that it gets the right answer.
Measurement and Data
10 standardsKY.2.MD.1
Pick the right tool, like a ruler, yardstick, meter stick or measuring tape, and measure how long an object is.
KY.2.MD.2
Measure the same object in two different units, like inches and centimeters, and explain why the smaller unit gives a bigger number.
KY.2.MD.3
Estimate how long things are in inches, feet, yards, centimeters, and meters.
KY.2.MD.4
Measure two objects to find how much longer one is than the other, giving the difference in a customary or metric unit, like 3 inches longer.
KY.2.MD.5
Solve length word problems within 100 by adding or subtracting measurements in the same unit, showing the problem with a drawing or an equation with a blank.
KY.2.MD.6
Show whole numbers as distances from 0 on an evenly spaced number line and use the line to model sums and differences within 100.
KY.2.MD.7
Tell and write the time to the nearest five minutes on both clock faces and digital clocks, with a.m. and p.m.
KY.2.MD.8
Solve money word problems within 100 using the $ and ¢ symbols correctly, working with dollars or with cents but not both, and without decimals.
KY.2.MD.9
Ask a statistical question about measurements, measure several objects or one object repeatedly to the nearest whole unit, and show the data on a dot plot.
KY.2.MD.10
Make a picture graph and a bar graph with a scale of one for data with up to four categories, and use the bar graph to solve put-together, take-apart, and compare problems.
Geometry
3 standardsKY.2.G.1
Recognize and draw shapes with given features, like a set number of sides or angles, and name triangles, quadrilaterals, pentagons, hexagons, and cubes, counting a cube's faces.
KY.2.G.2
Split a rectangle into rows and columns of equal squares and count how many squares there are.
KY.2.G.3
Cut circles and rectangles into halves, thirds and fourths, and know that equal shares of the same whole can have different shapes.
