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 using mental strategies, and by year end know all sums of two one-digit numbers and their related differences by heart.
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 a rectangular array of up to 5 rows and 5 columns by adding, and write it as a sum of equal numbers, like 3 + 3 + 3 + 3.
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 1,000, skip-count by fives, tens, and hundreds, and spot the patterns when skip counting from any number, like 35, 45, 55.
2.NBT.A.3
Read and write numbers up to 1,000 as digits, as words, and in expanded form, like 482 = 400 + 80 + 2.
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 1,000 with models, drawings, and place value, tied to a written method, working with hundreds, tens, and ones and regrouping as needed.
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
Solve word problems with dollar bills and coins up to $10, writing amounts with $ and ¢, like 2 dimes and 3 pennies make 23¢, without using decimals.
2.MD.D.9
Measure several objects, or one object several times, to the nearest whole unit, and show the measurements on a line plot, also called a dot 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
Draw and recognize shapes with a set number of angles or equal faces, and name squares, rectangles, rhombuses, trapezoids, triangles, 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.
