26 standards
Operations and Algebraic Thinking
4 standards2.OA.A.1
Solve one- and two-step word problems within 100 by adding and subtracting, with the unknown in any position, like 25 + ? = 60.
2.OA.B.2
Add and subtract within 20 quickly with mental strategies, and know every sum of two one-digit numbers by heart by the end of second grade.
2.OA.C.3
Tell whether a group of up to 20 objects is odd or even, and write an even number as a double, like 8 = 4 + 4.
2.OA.C.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 standards2.NBT.A.1
Know what each digit of a three-digit number is worth, like 347 is 3 hundreds, 4 tens and 7 ones, and that 100 is a bundle of ten tens.
2.NBT.A.2
Count up to 1000 from any starting number, and skip-count by 5s, 10s and 100s, like 300, 400, 500.
2.NBT.A.3
Read and write numbers to 1000 as digits, in words, and in expanded form, like 426 as 400 + 20 + 6.
2.NBT.A.4
Compare two three-digit numbers by their hundreds, tens and ones, and record the answer with >, = or <.
2.NBT.B.5
Add and subtract within 100 quickly and accurately, using place value and the link between addition and subtraction.
2.NBT.B.6
Add up to four two-digit numbers at once, like 23 + 45 + 12 + 30, by grouping tens and ones.
2.NBT.B.7
Add and subtract within 1000 with models and place value, working hundreds, tens and ones separately, regrouping when needed, and explain the reasoning in writing.
2.NBT.B.8
Add or subtract 10 or 100 in their head from any number between 100 and 900, like 540 + 100 = 640.
2.NBT.B.9
Explain why an adding or subtracting strategy works, not just that it gets the right answer.
Measurement and Data
10 standards2.MD.A.1
Pick the right tool, like a ruler, yardstick, meter stick or measuring tape, and measure how long an object is.
2.MD.A.2
Measure the same object in two different units, like inches and centimeters, and explain why the smaller unit gives a bigger number.
2.MD.A.3
Make a sensible guess at a length in inches, feet, centimeters or meters before measuring it.
2.MD.A.4
Measure two objects and say how much longer one is than the other, like 3 inches longer.
2.MD.B.5
Solve word problems about lengths in the same unit by adding and subtracting within 100, with drawings and equations to help.
2.MD.B.6
Show whole numbers as lengths from 0 on a number line, and use the number line to add and subtract within 100.
2.MD.C.7
Tell and write the time to the nearest five minutes on both clock faces and digital clocks, with a.m. and p.m.
2.MD.C.8
Count up coins and dollar bills to solve money word problems, like 2 dimes and 3 pennies make 23¢, and write amounts with $ and ¢.
2.MD.D.9
Measure several objects to the nearest whole unit and show the results on a line plot.
2.MD.D.10
Draw picture graphs and bar graphs with up to four categories, and use a bar graph to answer how many more or how many in all.
Geometry
3 standards2.G.A.1
Recognize and draw shapes by their features, like a shape with five angles, and name triangles, quadrilaterals, pentagons, hexagons and cubes.
2.G.A.2
Split a rectangle into rows and columns of equal squares and count how many squares there are.
2.G.A.3
Cut circles and rectangles into halves, thirds and fourths, and know that equal shares of the same whole can have different shapes.
