35 standards

Standards for Mathematical Practice

8 standards
2.SMP.1
Plan a path through one- and two-step word problems within 100 and keep going when stuck, like trying a drawing when a first idea fails.
2.SMP.2
Turn a word problem about money or length into numbers and back, like using 45 + 28 for two jump ropes and telling what the sum means.
2.SMP.3
Defend an answer to an addition or subtraction problem within 1000 with models or place value, and respond to a classmate's reasoning.
2.SMP.4
Show real situations with bar models, number lines or equations, like a tape diagram for 63 marbles when 27 are given away.
2.SMP.5
Pick suitable tools such as rulers, yardsticks, base ten blocks, clocks or coins to solve measurement, time and money problems.
2.SMP.6
Measure and label units exactly and use correct math words, like writing 34 cm and reading a clock to the nearest five minutes.
2.SMP.7
Use place value structure to compute, like seeing 300 + 40 + 7 in 347 or splitting 58 + 37 into tens and ones.
2.SMP.8
Notice repeated steps in calculations, like skip-counting by 5s or seeing that adding 100 changes only the hundreds digit, and use them as shortcuts.

Operations and Algebraic Thinking

4 standards
2.OA.1
Solve one- and two-step word problems within 100 by adding and subtracting, with the unknown in any position, like 25 + ? = 60.
Common Core 2.OA.1
2.OA.2
Add and subtract within 20 in their head, and know every sum of two one-digit numbers by heart.
Common Core 2.OA.2
2.OA.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.
Common Core 2.OA.3
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.
Common Core 2.OA.4

Number and Operations in Base Ten

9 standards
2.NBT.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.
Common Core 2.NBT.1
2.NBT.2
Count within 1000, skip-count by 5s from numbers ending in 0 or 5, and skip-count by 10s and 100s from any number, like 37, 47, 57.
2.NBT.3
Read and write numbers to 1000 as digits, in words, and in expanded form, like 426 as 400 + 20 + 6.
Common Core 2.NBT.3
2.NBT.4
Compare two three-digit numbers by their hundreds, tens and ones, and record the answer with >, = or <.
Common Core 2.NBT.4
2.NBT.5
Add and subtract within 100 quickly and accurately, using place value and the link between addition and subtraction.
Common Core 2.NBT.5
2.NBT.6
Add up to four two-digit numbers at once, like 23 + 45 + 12 + 30, by grouping tens and ones.
Common Core 2.NBT.6
2.NBT.7
Add and subtract within 1000 with models and drawings, working hundreds with hundreds and tens with tens, and regrouping when needed.
Common Core 2.NBT.7
2.NBT.8
Add or subtract 10 or 100 in their head from any number between 100 and 900, like 540 + 100 = 640.
Common Core 2.NBT.8
2.NBT.9
Explain why an adding or subtracting strategy works, not just that it gets the right answer.
Common Core 2.NBT.9

Measurement and Data

11 standards
2.MD.1
Pick the right tool, like a ruler, yardstick, meter stick or measuring tape, and measure how long an object is.
Common Core 2.MD.1
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.
Common Core 2.MD.2
2.MD.3
Make a sensible guess at a length in inches, feet, centimeters or meters before measuring it.
Common Core 2.MD.3
2.MD.4
Measure two objects and say how much longer one is than the other, like 3 inches longer.
Common Core 2.MD.4
2.MD.5
Solve word problems about lengths in the same unit by adding and subtracting within 100, with drawings and equations to help.
Common Core 2.MD.5
2.MD.6
Show whole numbers as lengths from 0 on a number line, and use the number line to add and subtract within 100.
Common Core 2.MD.6
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.
Common Core 2.MD.7
2.MD.8a
Count up coins and dollar bills to solve money word problems, like 2 dimes and 3 pennies make 23¢, and write amounts with $ and ¢.
Common Core 2.MD.8
2.MD.8b
Use a calendar with ease to answer everyday questions, like how many weeks are in a year or how much an allowance adds up to over months.
2.MD.9
Measure several objects to the nearest whole unit and show the results on a line plot.
Common Core 2.MD.9
2.MD.10
Make picture graphs and bar graphs with a scale of one for data in up to four categories, then solve put-together, take-apart and compare problems from a bar graph.

Geometry

3 standards
2.G.1
Recognize and draw shapes by their features, like a shape with five angles, and name triangles, quadrilaterals, pentagons, hexagons and cubes.
Common Core 2.G.1
2.G.2
Split a rectangle into rows and columns of equal squares and count how many squares there are.
Common Core 2.G.2
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.
Common Core 2.G.3
