Mathematical Practices

8 standards
2.MP.1
Make sense of a problem before solving and keep at it, like rereading a two-step word problem about money and trying another strategy when stuck.
2.MP.2
Move between numbers and real situations, like writing 45 - 18 for a story about stickers and explaining what the answer means.
2.MP.3
Defend a solution with reasons and question others' reasoning, like explaining why 10 more than 356 is 366 and checking a partner's work.
2.MP.4
Represent everyday problems with math, like using a number line, bar model or equation to solve a problem about saving coins.
2.MP.5
Choose tools that fit the task, like a ruler or yardstick to measure, base ten blocks to add, or a clock to find elapsed time.
2.MP.6
Be exact in math, like measuring to the nearest inch, writing cents and dollar signs correctly and using words like hexagon accurately.
2.MP.7
Use how numbers are built to solve problems, like seeing 243 as 2 hundreds, 4 tens and 3 ones, or 7 + 8 as one more than 7 + 7.
2.MP.8
Notice repeating results and use them, like seeing that adding 10 changes only the tens digit, or that doubles always make even numbers.

Numerical Reasoning

9 standards
2.NR.1.1
Explain what a three-digit number is worth by breaking it into hundreds, tens and ones in different ways, like 352 as 35 tens and 2 ones.
2.NR.1.2
Count by ones up or down from any number to 1000, by fives up from multiples of 5, by 10s and 100s up or down, and by 25s up from 0.
2.NR.1.3
Show, compare and order whole numbers up to 1000 by looking at place value, and record each comparison with a symbol, like 457 > 449.
2.NR.2.1
Add and subtract within 20 quickly, accurately and mentally, using part-whole methods like making a ten or breaking a number into parts.
2.NR.2.2
Use place value to jump 10 or 100 up or down from any three-digit number, like 472 to 482, 462, 572 or 372.
2.NR.2.3
Add and subtract two-digit numbers to solve problems by splitting them into parts, like 46 + 37 as 40 + 30 and 6 + 7.
2.NR.2.4
Add and subtract within 100 quickly and accurately, using place value and the link between addition and subtraction.
Common Core 2.NBT.5
2.NR.3.1
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 14 = 7 + 7.
2.NR.3.2
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

Patterning & Algebraic Reasoning

2 standards
2.PAR.4.1
Find, describe and make number patterns built by adding or subtracting the same amount again and again, like 3, 6, 9, 12.
2.PAR.4.2
Spot, explain and build patterns that grow or shrink through addition or subtraction up to 20, like 2, 4, 6, 8 or 20, 17, 14, 11.

Measurement & Data Reasoning

7 standards
2.MDR.5.1
Make a simple measuring tool from repeated unit pieces, like a paper strip marked in cube lengths, and compare it to a real ruler.
2.MDR.5.2
Estimate, then measure how long something is or how far apart things are to the nearest whole unit, picking fitting units and tools like a yardstick.
2.MDR.5.3
Measure two objects to find how much longer one is than the other, and state the difference in a standard unit, like 4 inches longer.
2.MDR.5.4
Ask and answer real-life questions using collected information, observations and graphs like picture graphs and bar graphs.
2.MDR.5.5
Show sums and differences of whole-number lengths on a number line marked in a standard unit, like jumping from 12 to 19 inches.
2.MDR.6.1
Read and write clock times to the nearest five minutes, and use a timeline to find elapsed hours or half hours from times on the hour or half hour.
2.MDR.6.2
Find the total of a set of coins, find coins that make an amount under one dollar, and solve problems with bills and coins using the $ and ¢ signs.

Geometric & Spatial Reasoning

4 standards
2.GSR.7.1
Describe, compare and sort flat shapes like triangles, quadrilaterals, pentagons and hexagons and solids like rectangular prisms and cones by given features.
2.GSR.7.2
Spot a fold line that splits an everyday object like a leaf or a door into two matching halves, and use that symmetry to describe the whole object.
2.GSR.7.3
Cut circles and rectangles into 2, 3 or 4 same-size shares and name the parts with words like halves, thirds, fourths, half of and quarter of.
2.GSR.7.4
Recognize that equal parts of the same-size whole can have different shapes, like halves of a square cut as two rectangles or two triangles.
