Common Core Standards for 2nd Grade Math
Operations and Algebraic Thinking OA 2.1 Use addition/ subtraction within 100 to solve one/ two step word problems OA 2.2 Fluently add/ subtract within 20 using mental strategies. By the end of grade 2, students need to memorize all sums of two one-digit numbers. OA 2.3 Determine if a group of objects has an odd/ even number OA 2.4 Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows/columns Number and Operations in Base Ten NBT 2.1 Understand place value up to three digits (hundreds, tens, ones) NBT 2.2 Count within a 1000 (skip count by 2, 5, 10, 100) NBT 2.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form NBT 2.4 Compare two three-digit numbers using <, >, = NBT 2.5 Fluently add/subtract within 100 NBT 2.6 Add up to 4 two-digit numbers NBT 2.7 Add/ subtract within 1000 NBT 2.8 Mentally add/ subtract 10 or 100 to a given number NBT 2.9 Explain why addition/subtraction strategies work, using place value and the properties of operations. | Measurement and Data MD 2.1 Measure the length of an object using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. MD 2.2 Measure the length of an object twice, using length units of different lengths for the two measurements MD 2.3 Estimate lengths using units of inches, feet, centimeters, and meters MD 2.4 Measure to determine how much longer one object is than another MD 2.5 Use addition/ subtraction within 100 to solve word problems involving length MD 2.6 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ... MD 2.7 Tell and write time from an analog and digital clock to nearest five minutes, using am/pm. Also, know relationships of time (minutes in an hour, days in a month, weeks in a year) MD 2.8 Solve word problems involving combinations of dollar bills, quarters, dimes, nickels, and pennies using $ and cent symbols appropriately MD 2.9 Generate measurement data by measuring lengths of several objects to nearest whole unit. Show measurements by making a line plot. MD 2.10 Draw a picture graph and bar graph to represent a data set with up to 4 categories. Solve problems using graphs. Geometry G 2.1 Recognize and draw shapes having specified attributes, such as a given number of angles or faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. G 2.2 Partition a rectangle into rows/ columns of same-size squares and count to find the total number G 2.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using words halves, thirds, half of, third of, etc. |
