2nd grade math worksheets

Counting & number sense

• Greater than, less than Compare the biggest place first: the open side of the symbol faces the bigger number.
  Print
• Ordering numbers Compare the numbers place by place, then write them in the order asked.
  Print
• Skip counting to 1,000 Find the step first: does the row go up by 5, by 10, or by 100? Then keep that step for every blank.
  Print

Place value & rounding

• 10 or 100 more or less Ten more or less moves the tens digit. One hundred more or less moves the hundreds digit. The other digits stay put.
  Print
• Expanded form Expanded form stretches a number out to show what each digit is worth, like 358 = 300 + 50 + 8.
  Print
• Hundreds, tens & ones A 3-digit number is made of hundreds, tens, and ones. Count each kind, then write the digits in order.
  Print

Facts & fluency

• Addition mad minute Work fast and left to right. Skip a hard one and come back; the clock does not wait.
  Print
• Addition within 20 Make a ten first when you can. It turns hard facts like 9 + 6 into easy ones like 10 + 5.
  Print
• Balancing equations The equal sign means both sides are the same amount, so check that they balance.
  Print
• Fact families The three numbers in the roof are a family. Write all four facts they make together.
  Print
• Missing addends Find the number that makes the equation true. Count up from the part you already know.
  Print
• Subtraction within 20 Think addition to subtract: for 13 − 8, ask what you add to 8 to make 13.
  Print

Multi-digit addition & subtraction

• Addition with regrouping Add the ones first. When they make ten or more, write the ones digit and carry the ten to the next column.
  Print
• Mental math Turn hard numbers into friendly ones: to add 29, add 30 and then take 1 back.
  Print
• Subtraction with regrouping If the top digit is smaller, borrow: take one ten from the next column and add ten to the digit you are subtracting from.
  Print
• Three-digit addition & subtraction Check the sign first, then work one column at a time starting from the ones.
  Print
• Two-digit addition Add the ones first. If they make ten or more, carry a ten to the tens column.
  Print
• Two-digit subtraction with regrouping If the top ones digit is too small, trade one ten for ten ones before you subtract.
  Print

• Multiplication facts 0–12 Multiplication is repeated addition. When you know your times tables, you can solve problems quickly without counting on your fingers.
  Print

• Addition & subtraction word problems Read the whole story before you pick a sign. Does it put amounts together, or take some away?
  Print
• Addition word problems Read the whole story, then find the question. If groups are coming together, add.
  Print
• Measurement word problems Look for the units in the story. Your answer needs a unit too, so write it every time.
  Print
• Money word problems Count the coins from the biggest value down. When the story asks for change, start at the cost and count up.
  Print
• Multiplication word problems Look for equal groups in the story. Same-size groups, counted in one move: that is multiplication.
  Print
• Subtraction word problems Read the story and find the question. If something goes away, or two amounts get compared, subtract.
  Print
• Two-step word problems Read each story. Show how you find the missing quantity.
  Print

• Even & odd numbers Even numbers split into pairs with none left over. Check the ones digit: 0, 2, 4, 6, and 8 mean even.
  Print

• Unit fractions & parts of a whole The bottom number counts the equal parts in the whole. The top number counts the shaded parts.
  Print

• Identifying 3d shapes Solid shapes take up space. Name the whole solid, not just the flat face you can see.
  Print
• Partitioning shapes Equal shares means every piece is exactly the same size, a fair share for everyone.
  Print
• Sides & vertices Sides are the straight edges and vertices are the corners. Mark where you start so you count each one just once.
  Print
• Partitioning rectangles Finish each grid with equal squares. Then count the squares.
  Print

• Counting coins Count the coins that are worth the most first, then count on. A dime is small, but it is worth 10 cents.
  Print
• Making change Start at the cost and count up to the money paid. What you count along the way is the change.
  Print
• Measuring length Find where the bar starts and where it ends. The length is the distance between them.
  Print
• Telling time The short hand tells the hour and the long hand tells the minutes. Read the short hand first.
  Print
• Estimating length Choose a sensible estimate for each object. Pictures are not actual size.
  Print
• Length word problems Complete each problem. Write the answer with its unit when needed.
  Print
• Drawing clock hands Draw a short hour hand and a long minute hand for each time.
  Print

• Bar & line plots Read the scale, not the picture: the height of a bar or the count of Xs tells you the number.
  Print
• Pictographs Read the key first. Count the symbols, then multiply by what each one stands for.
  Print
• Tally charts Count tally bundles by fives. The stroke that crosses the group is the fifth mark, not an extra one.
