What second grade math covers

The Common Core gives grade 2 four focus areas: base-ten notation, fluency with addition and subtraction, standard units of measure, and shapes. Fluency means within 100 (2.NBT.5); within 1,000 it asks for models and strategies, not speed. These grade 2 math worksheets are mostly number work, with no shape, graph or even and odd sheet.

Where Texas and the Common Core differ

Math worksheets for grade 2 depend on the state. Texas takes numbers to 1,200 and word problems to 1,000; the Common Core stops at 1,000 and 100. Texas reads clocks to the minute, the Common Core to five minutes. Texas uses halves, fourths and eighths and saves thirds for grade 3. Even and odd runs to 40 in Texas, 20 in the Common Core.

  • The 36 sums past 10, such as 8 + 5, are the second grade math facts that need a strategy.
  • For 60 − 27, an answer of 47 means the child took the 0 away from the 7.

Questions and answers

What are the math facts 2nd grade students must know?

Every sum of two one-digit numbers, from memory, by the end of the year (Common Core 2.OA.2): 81 sums, from 1 + 1 to 9 + 9. Texas asks for facts within 20 with automaticity. The 2nd grade math facts worksheets are the first topic.

Are these 2nd grade math worksheets free printables?

Yes. Every math worksheet grade 2 teachers and parents make here is free. Press Print, and the answer key follows as page 2. For 2nd grade math worksheets PDF copies, save as PDF from your browser's print window.

Where are the 2nd grade math worksheets word problems?

On their own page. 2nd grade word problems prints one-step stories within 100: adding, taking away, comparing and lengths. The sheets on this page are number work. Second graders are usually 7 to 8 years old.

Which are the fun easy 2nd grade math worksheets?

Count by 100s to 1,000 is the gentlest sheet here: 10 rows, and only the hundreds digit moves. Count by 5s within 1,000 comes next: its ones digit goes 5, 0, 5, 0.

All 36 sheet types

Addition and subtraction facts within 20 4

  • Addition facts within 20, 40 problems 8 + 7 = 15. The sheet draws from the 190 different additions of two numbers from 1 up whose sum is 20 or less, so 14 + 5 = 19 can sit beside 8 + 7. Forty problems across the page, with the key on page 2.
  • Every one-digit sum, 1 + 1 to 9 + 9 9 + 6 = 15. Both numbers have one digit, so no sum is above 9 + 9 = 18. Counting 9 + 6 and 6 + 9 separately there are 81 of these sums, the ones the Common Core asks children to know from memory by the end of grade 2.
  • Subtract from the teens, such as 14 − 6 14 − 6 = 14 − 4 − 2 = 10 − 2 = 8. Take away enough to land on 10, then take away the rest. Every problem starts between 11 and 18 and has a one-digit answer, 36 problems in all.
  • Subtraction facts within 20, 40 problems 15 − 8 = 7. The same 190 number pairs read the other way: the larger number is 20 or less and the answer is never 0. A child who stalls can think of the addition instead, 8 + 7 = 15.

Add within 100 4

  • Add 2-digit numbers with regrouping 38 + 47 = 85. The ones make 8 + 7 = 15, so write 5 and carry 1 ten: 3 + 4 + 1 = 8 tens. Every problem on the sheet makes a new ten from its ones.
  • Add 2-digit numbers without regrouping 42 + 35 = 77. Ones first, 2 + 5 = 7, then tens, 4 + 3 = 7. No column reaches 10, which makes this the sheet for learning the stacked layout before any carrying.
  • Add up to four 2-digit numbers 23 + 31 + 14 + 22 = 90. The ones make 3 + 1 + 4 + 2 = 10, so 1 ten is carried: 2 + 3 + 1 + 2 + 1 = 9 tens. Look for ones that make 10 before adding down the column.
  • Add within 100, stacked 38 + 47 = 85. Two numbers are set one above the other and their sum is 100 or less. Some problems make a new ten, some do not, and some add a one-digit number, so a child has to look at the ones before starting.

Subtract within 100 4

  • Subtract 2-digit numbers with regrouping 82 − 47 = 35. 2 ones are too few to take 7 from, so trade 1 ten for 10 ones: 12 − 7 = 5 ones, and 7 − 4 = 3 tens are left. Every problem needs the trade.
  • Subtract 2-digit numbers without regrouping 78 − 35 = 43. Ones, 8 − 5 = 3, then tens, 7 − 3 = 4. Every ones digit on top is at least as large as the one below it, so no ten is ever traded.
  • Subtract from a multiple of 10, such as 60 − 27 60 − 27 = 33. There are no ones on top, so a ten is traded at once: 10 − 7 = 3 ones and 5 − 2 = 3 tens. A child who writes 47 has taken the 0 away from the 7.
  • Subtract within 100, stacked 82 − 47 = 35. The top number is 100 or less and the answer is never 0. Problems that need a trade are mixed with problems that do not, so the first job in each one is to compare the two ones digits.

Add and subtract within 1,000 3

  • Add or subtract 10 or 100 in your head 347 + 100 = 447 and 347 − 10 = 337. Most of the time one digit changes. 395 + 10 = 405 changes two, and those are the ones to watch. The starting numbers run from 100 to 900, the range the Common Core names.
  • Differences within 1,000, stacked 725 − 268 = 457. Two trades here: 15 − 8 = 7 ones, 11 − 6 = 5 tens and 6 − 2 = 4 hundreds. The Common Core asks for this range in grade 2 with drawings and place value strategies, and for fluency within 1,000 in grade 3.
  • Sums up to 1,000, stacked 457 + 268 = 725. Any two numbers with a sum of 1,000 or less, so some problems regroup twice and some add a small number to a large one. Twelve to a page leaves room to write the carried digits.

Place value to 1,000 (1,200 in Texas) 6

  • 10 less, 10 more, 100 less, 100 more: fill the table For 395 the row reads 295, 385, 395, 405, 495. Going from 395 to 405 changes two digits, which is the box to watch. Numbers go up to 1,100, so 100 more stays inside the Texas limit of 1,200.
  • Compare 3-digit numbers with <, > or = 482 < 487, because the hundreds and the tens match and 2 ones are fewer than 7. The two numbers often share their first digits on this sheet, so a child has to read past the hundreds.
  • Expanded form with a zero, such as 706 706 = 700 + 6. A place that holds 0 adds no part, so this number has two parts and not three. The Common Core's own example is 706: 7 hundreds, 0 tens and 6 ones.
  • Expanded form, 3-digit numbers 347 = 300 + 40 + 7. No digit is 0 on this sheet, so every number has three parts. The 4 stands for 40, not for 4, which is the point of writing the parts out.
  • Order three numbers, to 1,200 465, 456, 546 → 456 < 465 < 546. Compare hundreds first, then tens, then ones. The Common Core compares two 3-digit numbers in grade 2. Texas also orders them and goes up to 1,200, so this sheet does both.
  • Parts to a number, up to 1,200 1,000 + 100 + 40 + 6 = 1,146. Add the parts and write the number. Texas takes grade 2 numbers up to 1,200 and the Common Core stops at 1,000, so some answers here have four digits.

Skip counting 4

  • Count by 5s within 1,000 235, 240, 245 and then three blanks: 250, 255, 260. Every row starts on a multiple of 5 somewhere below 1,000, and the ones digit goes 5, 0, 5, 0 all the way along.
  • Count by 10s from any number 347, 357, 367 and then 377, 387, 397. The ones digit never changes and the tens go up by one. Rows that pass a hundred, such as 487, 497, 507, are the hard ones.
  • Count by 100s to 1,000 125, 225, 325 and then 425, 525, 625. Three numbers are given and the child writes the next three. Only the hundreds digit moves, whether a row starts on 200 or on 125, and no row passes 1,000.
  • Which rule: 5s, 10s or 100s? 210, 220, 230, 240: the next two numbers are 250 and 260, and the rule is count on by 10. The child has to find the step before using it, the reverse of the three counting sheets.

Time and money 8

  • A.M. or P.M.? School day sentences Breakfast at 7:15 is a.m. and going home from school at 3:20 is p.m. Both standards ask second graders to tell the two apart. Sentences only, and the child circles a.m. or p.m.
  • Coin values in words, no pictures 3 dimes and 4 pennies: 30 + 4 = 34 cents. Work out each kind of coin, then add, which is how the answer key shows it. The Common Core's own example is 2 dimes and 3 pennies. Without pictures the child has to know each coin's value from its name.
  • Count coins up to one dollar 2 quarters, 1 dime, 1 nickel and 2 pennies: 25 + 25 + 10 + 5 + 1 + 1 = 67 cents. Each coin is drawn as a plain shape with its value printed on it, largest first, so the child starts with the largest and counts on. Texas keeps grade 2 collections to one dollar or less.
  • Draw the hands, times to five minutes For 8:10 the long hand points at the 2 and the short hand sits just past the 8, one sixth of the way to the 9. The clock faces are printed without hands, and the key shows them finished.
  • Minutes past and minutes to the hour 4:40 is 40 minutes past 4 and 20 minutes to 5, because 40 + 20 = 60. No clock is drawn. Each line gives a digital time and asks for both ways of saying it.
  • Read the clock to five minutes The long hand on the 7 means 35 minutes, because 7 fives are 35. With the short hand between the 7 and the 8, the time is 7:35. The Common Core reads clocks to five minutes in grade 2.
  • Read the clock to one minute (Texas) At 10:37 the long hand is 2 small marks past the 7, and 35 + 2 = 37. Texas asks for time to the minute in grade 2 (2.9(G)). The Common Core waits until grade 3.
  • Write amounts with the dollar sign and the cent sign A dollar bill, a quarter and a dime: 100 + 25 + 10 = 135 cents, written $1.35. A quarter and a dime make 35¢. Amounts under a dollar take the cent sign, a dollar or more takes the dollar sign and a decimal point, and no amount takes both. Collections go up to $5.

Rulers and rectangles 3

  • Measure a bar with a centimeter ruler A bar from the 0 mark to the 9 mark is 9 centimeters long. The ruler is numbered 0 to 12 in centimeters and every bar starts at 0. The Common Core names inches, feet, centimeters and meters for grade 2 (2.MD.3). Texas asks for the nearest marked unit on a ruler, yardstick, meter stick or measuring tape (2.9(D)).
  • Measure a bar with an inch ruler A bar from the 0 mark to the 7 mark is 7 inches long. Each box draws a bar above a ruler numbered 0 to 12, and every bar ends on an inch mark. The child writes the number beside the printed unit. The rulers are not drawn life size, so the length is read, not measured.
  • Rows and columns of squares in a rectangle A rectangle 3 squares tall and 4 squares wide: 4 + 4 + 4 = 12 squares. Count one row, then add the rows. The Common Core treats this as a shape topic in grade 2. Texas already calls it area.
