2.NBT.A.2

Read & Write Numbers

Reading & Writing Numbers

Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

2.NBT.A.3

Compare

Comparing Numbers

Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

2.NBT.A.4

Operations Using Place Value

Place value up to 100

Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

2.NBT.B.5

Adding with 3 or more

Add up to four two-digit numbers using strategies based on place value and properties of operations.

2.NBT.B.6

Place value up to 1000: I

Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method.

2.NBT.B.7

Place value up to 1000: II

Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.

2.NBT.B.8

Shapes

Defining Shapes

Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.1 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

2.G.A.1

Partitioning

Partition a rectangle into rows and columns of same-size squares and count to find the total number of them. Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

2.G.A.2, 2.G.A.3

Length & Distance

Measurement

Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen. Estimate lengths using units of inches, feet, centimeters, and meters.

2.MD.A.1, 2.MD.A.2, 2.MD.A.3

Longer & Shorter

Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units.

2.MD.A.4, 2.MD.B.5

Longer & Shorter: Equations

Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units.

2.MD.B.5

Number Line

Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent whole-number sums and differences within 100 on a number line diagram.

2.MD.B.6

Time & Money

Time

Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.

2.MD.C.7

Money

Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.

2.MD.C.8

Data

Graph

Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.
