Aligned Standard

M.EE.3.OA.4: Solve addition and subtraction problems when result is unknown, limited to operands and results within 20.

Grade Level Standard

This is aligned with the following California State Standards:

  • 3.OA.4 - Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 ? = 48, 5 = ? 3, 6 6 = ?.

Linkage Level Descriptions

Initial Precursor

Communicate understanding of separateness by recognizing objects that are not joined together. Communicate understanding of a set by recognizing a group of objects sharing an attribute.

Distal Precursor

Combine two or more sets of objects to create a new set. Divide a set of 10 or fewer objects into two or more distinct subsets. Demonstrate an understanding of addition by combining the objects of both the sets, and demonstrate an understanding of subtraction by removing some objects from a larger set.

Proximal Precursor

Identify the addition, subtraction, and equal signs. Understand that the + sign indicates the numbers on either side of the sign should be added together, that the - sign indicates one number should be taken away from another number, and that the = sign indicates that quantities on either side represent the same value. Represent addition or subtraction word problems or models with equations (e.g., representing 6 marbles

Target

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 = ?).

Successor

Determine the unknown quantity in join, part-part-whole, compare, or separate word problems.
