Standards with the same topic and subject but for other grades
Fluently (i.e. automatic recall based on understanding) add and subtract within 5.
Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
Students will demonstrate the meaning of addition and subtraction with whole numbers and compute accurately.
Decompose numbers less than or equal to 10 into pairs in more than one way, showing each decomposition with a model, drawing, or equation (e.g., 7 = 4 + 3 and 7 = 1 + 6).
Solve real-world problems that involve addition and subtraction within 10 (e.g., by using objects, drawings or equations to represent the problem).
For any number from 1 to 9, find the number that makes 10 when added to the given number, showing the answer with a model, drawing, or equation.
Fluently (i.e. automatic recall based on understanding) add and subtract within 20.
Fluently (i.e., automatic recall based on understanding) add and subtract within 10.
Add and subtract multi-digit numbers using the standard algorithm.
Add and subtract within 1,000 with or without regrouping.
Fluently add whole number facts with sums to 20
Decompose numbers and use the commutative and associative properties of addition to develop addition and subtraction strategies including (making 10's and counting on from the larger number) to add and subtract basic facts within 20 (e.g., decomposing to make 10, 7 + 5 = 7 + 3 + 2 = 10 + 2 = 12; using the commutative property to count on 2 + 6 = 6 + 2; and using the associative property to make 10, 5 + 3 + 7 = 5 + (3 + 7) = 5 + 10).
