21 1st grade standards with a printable sheet · Ages 6–7
The wording beside each code is our own short summary of what the standard asks for, not its official text. For that, see the Common Core State Standards Initiative.
Operations and Algebraic Thinking
OA- 1.OA.A.1
Add and subtract within 20 to solve word problems.
- 1.OA.A.2
Solve word problems adding three whole numbers within 20.
Partial Adds three one-digit numbers in a column. Is not a story, and a sum can pass 20.
- 1.OA.B.3
Apply the commutative and associative properties to add.
- 1.OA.B.4
Understand subtraction as an unknown-addend problem.
- 1.OA.C.5
Relate counting on and back to addition and subtraction.
- 1.OA.C.6
Add and subtract within 20, fluent within 10.
- 1.OA.D.7
Understand the meaning of the equal sign; judge true or false.
- 1.OA.D.8
Find the unknown number in an addition or subtraction equation.
Number and Operations in Base Ten
NBT- 1.NBT.A.1
Count to 120 and read and write numerals in that range.
- 1.NBT.B.2
Understand two-digit numbers as tens and ones.
- 1.NBT.B.3
Compare two two-digit numbers using >, = and <.
- 1.NBT.C.4
Add within 100, including a two-digit number and a multiple of ten.
- 1.NBT.C.5
Mentally find 10 more or 10 less than a two-digit number.
- 1.NBT.C.6
Subtract multiples of 10 from multiples of 10 within 100.
Partial Subtracts two-digit numbers in general. Does not keep to multiples of 10.
Measurement and Data
MD- 1.MD.A.1
Order three objects by length; compare lengths indirectly.
Partial Orders three pictured objects by length. Comparing two through a third needs the objects themselves.
- 1.MD.A.2
Measure length by iterating a shorter unit.
- 1.MD.B.3
Tell and write time to the hour and half-hour.
- 1.MD.C.4
Organize and interpret data in up to three categories.
Geometry
G- 1.G.A.1
Tell defining attributes of shapes from non-defining ones.
- 1.G.A.2
Compose two- and three-dimensional shapes.
Partial Composes flat shapes. Does not compose three-dimensional ones.
- 1.G.A.3
Partition circles and rectangles into halves and quarters.
Partial Names the fraction each part is. Does not ask the child to partition the shape.
Supplementary
Taught at this level and not part of the Common Core content standards. Listed so the catalog says what else is on the shelf.
Reading a thermometer is not in CCSS measurement; it arrives via science standards.
CCSS has no calendar standard. Time is 1.MD.B.3 / 2.MD.C.7 / 3.MD.A.1 and all three are clocks.
CCSS has no chance before 7.SP.C.5, and that standard asks for a probability as a number, not a word. Ontario and Australia teach the words from grade 1 and year 3.
