Four big ideas in first grade math
The Common Core names four critical areas for grade 1: adding and subtracting within 20, place value with tens and ones, measuring length by repeating a unit, and reasoning about shapes. It asks for fluency only within 10 (1.OA.6); larger facts use strategies such as making ten. This page has no shape, equal share or data sheet.
Texas and the Common Core in grade 1
Texas first graders skip count by twos, fives and tens, count backward from any number to 120, and learn the four coins (TEKS 1.4, 1.5). The Common Core leaves counting by fives and coins to grade 2 and asks instead for adding within 100, such as 34 + 50 (1.NBT.4). Texas facts and word problems stay within 20.
Print Doubles to 10 + 10 first: knowing 6 + 6 = 12 puts 6 + 7 one count away.
Fun math worksheets for 1st grade can be puzzles: Which rule: 2s, 5s or 10s? hides the counting rule.
On Hour or half hour? Read the mixed clocks, check the long hand first: 12 or 6.
Questions and answers
What are the 1st grade math facts?
The additions and subtractions within 20. The Common Core asks for fluency within 10 and strategies up to 20 (1.OA.6); Texas asks for basic fact strategies within 20 (TEKS 1.3(D)). Addition facts within 10, 30 problems draws from 45 different additions, none with a 0.
Are these free printable 1st grade math worksheets?

Where are the 1st grade math worksheets word problems?
One is here: How many more? Compare stories within 20, the last sheet type. Joining, taking away, three addends and missing parts are on 1st grade word problems. First graders are usually 6 to 7.
All 30 sheet types
Add within 20 3
Addition facts within 10, 30 problems4 + 5 = 9. Two numbers from 1 up with a sum of 10 or less make 45 different additions, and the sheet prints 30 of them with no repeats. The Common Core sets fluency within 10 as the grade 1 goal (1.OA.6), which makes this the sheet the page opens on.
Addition within 20, 30 problems9 + 6 = 15. The sum is 20 or less and neither number is 0, which allows 190 different additions, so 13 + 4 = 17 can sit beside 9 + 6. Move here once the facts within 10 come quickly.
Doubles to 10 + 107 + 7 = 14. All ten doubles from 1 + 1 to 10 + 10, each printed once in a mixed order. Near doubles are built on them, and so are subtractions such as 14 − 7.

Subtract within 20 2
Subtraction facts within 10, 30 problems9 − 5 = 4. The 45 addition pairs within 10 read the other way: the first number is 10 or less and no answer is 0. Thirty problems across the page, none of them twice.
Subtraction within 20, 30 problems15 − 6 = 9. The first number is 20 or less and the answer is never 0, which gives 190 different subtractions. An easy one such as 17 − 3 can land beside a hard one such as 15 − 6.
Count to 120 6
Count back from any number up to 12063, 62, 61, 60, 59, 58. Rows count down by ones from anywhere up to 120, and many step back over a ten. Counting backward is a Texas grade 1 skill (1.5(A)). The Common Core standard for this grade counts forward only.
Count by fives to 12035, 40, 45, 50, 55, 60. Rows start on a multiple of 5 and never pass 120. The same count finds the value of a row of nickels, which is how Texas uses it in 1.4(C).
Count by tens from any number, up to 12017, 27, 37, 47, 57, 67. The start is any number from 1 to 70, so most rows are off the decade: the ones digit holds still while the tens digit climbs. It is 10 more, five times over.
Count by twos to 12046, 48, 50, 52, 54, 56. Every row starts on an even number and gives the first three terms. Texas has first graders skip count by twos, fives and tens up to 120 (1.5(B)). The Common Core names skip counting by 5s, 10s and 100s in grade 2 (2.NBT.2).
Count on past 100, up to 12098, 99, 100, 101, 102, 103. Each row gives two numbers and four blanks, and every row starts between 85 and 115, where the pattern after 100 is new. Both sets of standards count to 120 in grade 1.
Which rule: 2s, 5s or 10s?32, 34, 36, 38 counts on by 2, and 40 and 42 come next. Each row shows four numbers, and the child writes the rule and the next two numbers. Rows that count by 2 or by 5 start on a multiple of that step. Texas asks for skip counting in grade 1 (1.5(B)).
Tens and ones, comparing and ordering 6
1 less, 1 more, 10 less, 10 more: fill the tableFor 80 the row reads 70, 79, 80, 81, 90. The middle column gives a number from 11 to 109 and the child fills the two columns on each side of it. Texas asks for 10 more and 10 less up to 120 (1.5(C)). The Common Core asks for it mentally with two-digit numbers (1.NBT.5).
Compare 2-digit numbers with <, > or =47 < 74. Many pairs share their digits or differ in one place only, such as 98 and 89, so the tens digit has to be read first. The Common Core compares two-digit numbers in grade 1, and Texas uses the three symbols up to 100.
Order three numbers, up to 12079 < 89 < 97. Three numbers that are easy to mix up go in order from least to greatest. Texas orders whole numbers up to 120 in grade 1 (1.2(F)), so some rows pass 100.
Past 100: parts to a number, up to 120 (Texas)100 + 10 + 6 = 116. Numbers from 101 to 120 built from a hundred, tens and ones, and 100 + 6 = 106 shows why the zero is needed. Texas takes place value to 120 in grade 1 (1.2(B), 1.2(C)). The Common Core's grade 1 place value standard is about two-digit numbers.
Split a 2-digit number into tens and ones47 = 40 + 7. Numbers from 21 to 99 with no zero digit, so every answer has a tens part and a ones part. This is expanded form at its smallest, and Texas names it in 1.2(C).
Tens plus ones make a number, such as 60 + 360 + 3 = 63. A multiple of 10 plus a one-digit number, written as one number up to 99. Texas lists exactly this sum as 1.3(A).
Add and subtract with 2-digit numbers 3
Add 10 or take away 10 in your head54 + 10 = 64 and 54 − 10 = 44. A two-digit number plus or minus 10, written across with the signs mixed. Only the tens digit changes, and the sheet is there to make that automatic.
Add a 1-digit number to a 2-digit number, no new ten34 + 5 = 39. The ones add to 9 or less, so the tens digit stays put. It is the first of the two cases the Common Core names in 1.NBT.4: a two-digit number plus a one-digit number.
Add tens to a 2-digit number, such as 34 + 5034 + 50 = 84. The second number is a multiple of 10 from 10 to 80 and the sum stays under 100. 3 tens and 5 tens make 8 tens, and the 4 ones ride along. The Common Core asks for this in grade 1 (1.NBT.4).
Time and coins 8
Clock facts: hands, hours and half hoursAt half past 4 the long hand points to 6. Twelve short questions about the two hands, the 60 minutes in an hour and the 30 in half an hour, with no clock to draw. It is the text-only partner to the clock sheets.
Count pennies, nickels or dimes, one kind at a time6 nickels: 5, 10, 15, 20, 25, 30 cents. Each row names a number of pennies, nickels or dimes, never mixed, and the child skip counts to find the value. Texas ties coin counting to counting by twos, fives and tens (1.4(C)).
Draw the hands, hour and half hour9:30. Each box prints a time in digits beside an empty clock face, and the child draws both hands. On a half hour the short hand belongs halfway to the next number, not on the 9.
Hour or half hour? Read the mixed clocks9:00 and 9:30 on the same page. Eight clocks, some on the hour and some on the half hour, in a mixed order. The first thing to check is the long hand: on the 12 or on the 6.
O'clock and half past: write the wordsA clock showing 2:30 is read as half past 2, and one showing 5:00 as 5 o'clock. The child looks at each clock and writes the time in words, with o'clock and half past printed in a word bank.
Read the clock to the half hour4:30. The long hand points at the 6 and the short hand sits halfway between the 4 and the 5, which is the part that gets misread. The hour is the number the short hand has already passed.
Read the clock to the hour3:00. Six clock faces with the long hand on the 12, and the child reads the short hand and writes the time the way a digital clock shows it. Any of the twelve hours can come up.
What is each coin worth? No picturesA nickel is worth 5¢ and a quarter is worth 25¢. Rows ask for a coin's value, for the coin that matches a value, and for swaps such as how many nickels make a dime. No drawing is needed. Coins are a Texas grade 1 topic (1.4(A)).
Measuring length 1
How many squares long? Measure a barA bar that spans 7 squares is 7 squares long. Each box lays a row of same-size squares under a bar, end to end with no gaps and no overlaps, and the child counts them and writes the number. Lengths run from 2 to 12 squares, always a whole number.
Word problems 1
How many more? Compare stories within 20One jar holds 12 marbles and another holds 8. How many more are in the first jar? 12 − 8 = 4. In a compare story nothing joins and nothing leaves, so the child has to see for themselves that it is a subtraction. Texas lists comparing beside joining and separating in 1.3(B).
