Common Core Standards
OA — Operations & Algebraic Thinking
Represent and solve problems involving addition and subtraction.
- 2.OA.1Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.
Add and subtract within 20.
- 2.OA.2Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Work with equal groups of objects to gain foundations for multiplication.
- 2.OA.3Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
- 2.OA.4Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
NBT — Number & Operations in Base Ten
Understand place value.
- 2.NBT.1Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.
- 2.NBT.2Count within 1000; skip-count by 5s, 10s, and 100s.
- 2.NBT.3Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
- 2.NBT.4Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
Use place value understanding and properties of operations to add and subtract.
- 2.NBT.5Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
- 2.NBT.6Add up to four two-digit numbers using strategies based on place value and properties of operations.
- 2.NBT.7Add 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.8Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
- 2.NBT.9Explain why addition and subtraction strategies work, using place value and the properties of operations.
MD — Measurement & Data
Measure and estimate lengths in standard units.
- 2.MD.1Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
- 2.MD.2Measure 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.
- 2.MD.3Estimate lengths using units of inches, feet, centimeters, and meters.
- 2.MD.4Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
Relate addition and subtraction to length.
- 2.MD.5Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units.
- 2.MD.6Represent 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.
Work with time and money.
- 2.MD.7Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
- 2.MD.8Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.
Represent and interpret data.
- 2.MD.9Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the data by making a line plot, where the horizontal scale is marked off in whole-number units.
- 2.MD.10Draw 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 problems using information presented in a bar graph.
G — Geometry
Reason with shapes and their attributes.
- 2.G.1Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
- 2.G.2Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
- 2.G.3Partition 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.
