26 standards
Operations and Algebraic Thinking
4 standardsM.2.OA.A.1
Solve one- and two-step story problems within 100 about joining, separating and comparing, with the unknown in any spot, using drawings and equations.
M.2.OA.B.2
Add and subtract within 20 in the head, flexibly and quickly, with strategies like making ten or knowing 12 - 8 = 4 from 8 + 4 = 12.
M.2.OA.C.3
Tell whether a group of up to 20 objects is odd or even, like by pairing them up, and write an even number as a double, like 8 = 4 + 4.
M.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 standardsM.2.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.
M.2.NBT.A.2
Count up to 1,000 and skip-count by 5s, 10s and 100s, like 150, 160, 170 or 300, 400, 500.
M.2.NBT.A.3
Read and write numbers up to 1,000 with digits, in words and in expanded form, like 482 = 400 + 80 + 2.
M.2.NBT.A.4
Compare two three-digit numbers by their hundreds, tens and ones, and show the result with words and the symbols >, = and <.
M.2.NBT.B.5
Add and subtract within 100 flexibly using place value and number properties, with drawings allowed when a subtraction needs a ten broken apart.
M.2.NBT.B.6
Add up to four two-digit numbers at once, like 23 + 45 + 12 + 30, by grouping tens and ones.
M.2.NBT.B.7
Add and subtract within 1,000 with models or drawings and place value, tie the work to a written method, and regroup tens or hundreds when needed.
M.2.NBT.B.8
Add or subtract 10 or 100 in their head from any number between 100 and 900, like 540 + 100 = 640.
M.2.NBT.B.9
Tell why a method for adding or subtracting works, pointing to place value and number properties, and backing it up with drawings or objects.
Measurement and Data
10 standardsM.2.MD.A.1
Pick the right tool, like a ruler, yardstick, meter stick or measuring tape, and measure how long an object is.
M.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.
M.2.MD.A.3
Make a sensible guess at a length in inches, feet, centimeters or meters before measuring it.
M.2.MD.A.4
Measure two objects and say how much longer one is than the other, like 3 inches longer.
M.2.MD.B.5
Solve adding and subtracting word problems within 100 about lengths in the same unit, using number lines and equations with an unknown.
M.2.MD.B.6
Show whole numbers as distances from 0 on an evenly spaced number line, and use it to show sums and differences within 100.
M.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.
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 ¢.
M.2.MD.D.9
Measure several objects to the nearest whole unit and show the results on a line plot.
M.2.MD.D.10
Draw picture graphs and bar graphs with a scale of one for data in up to four categories, and solve joining and comparing problems from a bar graph.
Geometry
3 standardsM.2.G.A.1
Recognize and draw shapes with given features, like a set number of angles, and name triangles, quadrilaterals, pentagons, hexagons and cubes.
M.2.G.A.2
Split a rectangle into rows and columns of equal squares and count how many squares there are.
M.2.G.A.3
Split circles and rectangles into 2, 3 or 4 equal parts, call them halves, thirds and fourths, and see that equal parts can differ in shape.
