How it works

Place value worksheets grade 1 classes can reprint with new numbers: tens plus ones to 99, counting by 10s, comparing, 10 more and 10 less, and counting to 120. The answer key prints on page 2.

What grade 1 place value covers

The Common Core keeps grade 1 place value to 2-digit numbers: two digits count tens and ones, 11 to 19 are a ten and some ones, and 10 to 90 are 1 to 9 tens. Pupils compare, find 10 more and 10 less, and count to 120. Texas takes place value itself to 120.

First grade place value worksheets in order

Build 47 with blocks first: 4 tens and 7 ones. Then print Expanded form to 99: tens plus ones to record it as 47 = 40 + 7. Follow with Compare when the tens match and 10 more and 10 less than a 2-digit number. After these place value worksheets 1st grade pupils are ready for From 100 to 120.

  • A pupil who writes 4 + 7 for 47 copied the digits. Build it with 4 tens blocks first.
  • Swapped pairs such as 27 and 72 show who reads from the right. Have pupils underline the tens digit.
  • Writing 10010 for one hundred ten is writing what was heard. Print Count on from any number to 120.

Questions and answers

Are place value worksheets first grade or second grade work?

Both. Grade 1 takes 2-digit numbers as tens and ones, and grade 2 adds hundreds. First grade children are usually 6 to 7, which is Year 2 in England and Wales. The Common Core first names expanded form in grade 2, Texas in grade 1.

Do 1st grade place value worksheets go past 100?

For counting, yes: the Common Core has grade 1 count, read and write numbers to 120 while place value stays with 2-digit numbers. Texas takes expanded form, ordering and 10 more and 10 less to 120, hence the From 100 to 120 group.

How do you teach 10 more and 10 less?

As a change in the tens digit, not as counting. In 33 + 10 = 43 the 3 tens become 4 tens and the ones stay put. Pupils can check on a number chart with 10 numbers in a row, where 10 more is one row down.

Tens plus ones: expanded form to 99 4

  • Add tens and ones to make a 2-digit number 60 + 3 = 63, and 3 + 60 = 63 as well. The first half of the sheet gives the tens first and the second half gives the ones first, so pupils look for the part that ends in 0. Texas names this sum for grade 1: a multiple of 10 plus a one-digit number.
  • Expanded form to 99: tens plus ones 47 = 40 + 7: the 4 stands for 4 tens, which make 40, and the 7 stands for 7 ones. Pupils split 12 two-digit numbers this way. A pupil who writes 4 + 7 has copied the digits and not what they are worth.
  • Find the missing tens or ones to 99 One part is missing on each of 12 lines. When the line shows 50, a gap and the total 58, the gap is 8. When it shows a gap, then 8 and the total 58, the gap is 50 and not 5, because 50 + 8 = 58.
  • Mixed expanded form practice to 99 All three jobs on one sheet: split a number, as in 73 = 70 + 3, put one together, as in 90 + 7 = 97, and fill in one missing part. Use it as a check after the three sheets above it. It has 12 lines and the key on page 2.

Counting by 10s, forward and back 3

  • Count back by 10s from any number 89, 79, 69, 59, 49, 39: the tens digit drops by 1 each time and the ones digit never changes. Rows start between 51 and 89 and hold 6 numbers. A pupil who writes 89, 88, 87 is counting back by ones.
  • Count by 10s from 10 to 100, forward and back 10, 20, 30, 40, 50, 60 counts on and 90, 80, 70, 60, 50, 40 counts back. Each row holds 6 decade numbers with the first 2 given, and half the rows count back. Say a row as 1 ten, 2 tens, 3 tens to tie counting to place value.
  • Count by 10s from any number: 7, 17, 27 7, 17, 27, 37, 47, 57: the ones digit stays 7 and the tens digit goes up by 1 each time. Rows start anywhere from 1 to 39. It is 10 more done five times over, and on a hundreds chart it is one column read downward.

Compare and order 2-digit numbers 6

  • Compare 2-digit numbers with <, > and = 47 > 43 and 27 < 72. The pairs look alike: the digits are swapped, or one digit is changed, and about 1 pair in 10 is equal. Pupils write the sign in the circle. Swapped pairs such as 27 and 72 catch a pupil who reads a number from the right.
  • Compare 2-digit numbers: look at the tens first 56 > 27, because 5 tens are more than 2 tens and no number of ones up to 9 can make up the gap. Both numbers are drawn at random here, so the tens usually differ. Use it before the look-alike pairs, and have pupils underline the tens digits.
  • Compare a 2-digit number with an expanded form 20 + 8 = 28 and 28 < 82, so 20 + 8 is less than 82. One side of each pair is an addition of tens and ones. A pupil who compares the 8 with 82, or the 20 with 82, has not added the parts yet.
  • Compare a 2-digit number with tens and ones One line has 33 on the left and 3 tens and 7 ones on the right. Build the right side first: 3 tens and 7 ones is 37, and 33 < 37. The key prints the built number beside the sign, so a wrong sign can be traced to its cause.
  • Compare when the tens match 58 < 59: both numbers have 5 tens, so the ones decide, and 8 ones are fewer than 9 ones. Every pair on this sheet shares its tens digit. It is the second half of the rule: compare the tens, and only when they match, compare the ones.
  • Order three 2-digit numbers 38, 83 and 33 in order are 33 < 38 < 83. The three numbers in a set look alike, and half the sets run from greatest to least. Compare the tens first; 38 and 33 tie on tens, so their ones settle it.

10 more, 10 less, 1 more, 1 less 4

  • 1 more and 1 less to 99 36 + 1 = 37 changes the ones digit only. The hard lines cross a decade: 39 + 1 = 40 and 40 − 1 = 39, where the tens digit changes as well. The sheet mixes more and less, so pupils read the sign first.
  • 1 more, 1 less, 10 more, 10 less table The row for 66 has 56 and 65 on its left and 67 and 76 on its right: 66 − 10 = 56 and 66 + 10 = 76. These are the four neighbors of 66 on a hundreds chart. Eight rows, each built around a number from 11 to 89.
  • 10 more and 10 less than a 2-digit number 33 + 10 = 43 and 71 − 10 = 61. Only the tens digit changes, by 1, and the ones digit stays put. The Common Core asks for this mentally, without counting, so cover the hundreds chart once pupils have seen the pattern.
  • Counting by 1s or by 10s? Find the rule 34, 35, 36, 37 counts on by 1, and 34, 44, 54, 64 counts on by 10. Pupils write the next 2 numbers and the rule for each row. Look at which digit changes: the ones digit for 1s, the tens digit for 10s.

From 100 to 120 6

  • 10 more and 10 less to 120 105 + 10 = 115 and 108 − 10 = 98. The numbers run from 90 to 110, so many answers cross 100. In 98 + 10 = 108 the 9 tens become 10 tens, which is written as 1 hundred and 0 tens.
  • Count back from 120 103, 102, 101, 100, 99, 98, 97: counting back through 100 drops from three digits to two. Rows start between 101 and 120. Texas asks grade 1 pupils to recite numbers forward and backward from any number between 1 and 120.
  • Count by 10s to 120 70, 80, 90, 100, 110, 120: the count by 10s does not stop at 100. After 10 tens come 11 tens, written 110, and 12 tens is 120. Rows hold 6 numbers: the first 2 are given and 3 of the other 4 are blank.
  • Count on from any number to 120 98, 99, 100, 101, 102, 103, 104: after 99 comes 100, and after 109 comes 110. Rows of 7 numbers start anywhere from 88 to 114, with the first 2 given. A pupil who writes 10010 for one hundred ten has written what they heard: 100, then 10.
  • Expanded form from 101 to 120 116 = 100 + 10 + 6 and 106 = 100 + 6. A place that holds 0 has no part, so 106 has two parts and 116 has three. Half the lines go from the parts back to the number. Texas takes expanded form to 120 in grade 1.
  • Order three numbers to 120 97, 120 and 105 in order are 97 < 105 < 120. A 3-digit whole number is always greater than a 2-digit one, so sort by the number of digits first. Half the sets run from greatest to least, and the signs on the line show which.
