M.EE.3.OA.8: Solve one-step real-world problems using addition or subtraction within 20.

Grade Level Standard

This is aligned with the following California State Standards:

  • 3.OA.8 - Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Linkage Level Descriptions

Initial Precursor

Combine two or more sets of objects or numbers to form a new set. Divide a set of 10 or fewer objects into two or more distinct subsets (e.g., dividing a set containing 10 objects into two subsets containing 4 and 6 objects).

Distal Precursor

Demonstrate understanding of addition by combining the objects of two or more sets and understanding of subtraction by removing some objects from a larger set.

Proximal Precursor

Find the unknown sum (e.g., 5 + 8 = ?) or the missing addend (e.g., 6 + ? = 10) in an addition equation. Find the unknown difference in a subtraction equation (e.g., 12 - 7 = ?).

Target

Solve addition and subtraction word problems within 20.

Successor

Use addition and subtraction to solve two-step word problems, including join, separate, part-part-whole, and compare problems.
