Second grade Math topics covered
Operations and algebraic thinking
- Use addition and subtraction within 100 to solve one- and two-step word problems
- Fluently add and subtract within 20 using mental strategies
- Work with equal groups of objects to gain foundations for multiplication
- Determine whether a group of objects has an odd or even number
Number and operations in base ten
- Understand that the three digits of a three-digit number represent hundreds, tens, and ones
- Count within 1000 by 1s, 5s, 10s, and 100s
- Read and write numbers to 1000 using base-ten numerals and expanded form
- Compare two three-digit numbers using >, =, and <
Measurement and data
- Measure the length of an object using appropriate tools
- Estimate lengths using inches, feet, centimeters, and meters
- Measure to determine how much longer one object is than another
- Solve word problems involving lengths
Geometry
- Recognize and draw shapes having specified attributes
- Identify triangles, quadrilaterals, pentagons, hexagons, and cubes
- Partition a rectangle into rows and columns of same-size squares
- Partition circles and rectangles into two, three, or four equal shares
Addition strategies and mental math
- Use the commutative property of addition to reorder addends and simplify computation
- Use the associative property of addition to regroup three or more addends
- Make a ten to add two single-digit numbers
- Add doubles and near-doubles within 20
Subtraction strategies and mental math
- Use the relationship between addition and subtraction to solve subtraction problems
- Subtract by counting up from the smaller number to the larger number
- Use think-addition strategies to find unknown differences within 20
- Subtract multiples of 10 from multiples of 10 within 100
Place value and number sense
- Identify the value of a digit in the hundreds, tens, or ones place of a three-digit number
- Represent three-digit numbers using base-ten blocks, drawings, and numerals
- Write three-digit numbers in word form
- Use place-value understanding to explain why 100 = 10 tens and 1000 = 10 hundreds
Addition and subtraction within 1000
- Add two three-digit numbers with and without regrouping
- Subtract two three-digit numbers with and without regrouping
- Explain why addition and subtraction strategies work using place-value understanding
- Use estimation to check whether an answer is reasonable
Time and calendar
- Tell and write time to the nearest five minutes using a.m. and p.m.
- Determine elapsed time in whole hours using a clock or number line
- Read and interpret a calendar including days, weeks, and months
- Solve word problems involving reading a clock or determining elapsed time
Money
- Identify and name the value of pennies, nickels, dimes, quarters, and dollar bills
- Count collections of coins and bills to find the total value
- Compare the values of two sets of coins or bills using >, =, and <
- Make change from a dollar using coins and bills
Data and graphs
- Collect and organize data into categories to create a tally chart
- Read and interpret picture graphs where each picture represents one or more objects
- Read and interpret bar graphs with a scaled axis (e.g., each square represents 2 or 5)
- Answer how many more and how many less questions using a bar graph
Fractions and equal shares
- Partition shapes into two, three, or four equal shares and describe the shares using the words halves, thirds, and fourths
- Identify and describe one-half, one-third, and one-fourth of a whole shape
- Understand that equal shares of identical wholes need not have the same shape
- Compare equal shares of differently shaped wholes (e.g., half of a circle vs. half of a square)
