Aligned Standard

M.3.OA.9: Identify models of one half (1/2) and one fourth (1/4).

Grade Level Standard

This is aligned with the following California State Standards:

  • 4.NF.1 - Explain why a fraction a/b is equivalent to a fraction (n a)/(n b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
  • 4.NF.2 - Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

Linkage Level Descriptions

Initial Precursor

Communicate understanding of separateness by recognizing objects that are not joined together. Communicate understanding of wholeness by recognizing an object that has all the parts joined together.

Distal Precursor

Divide familiar shapes, such as circles, triangles, squares, and/or rectangles, into two or more distinct parts. These parts may or may not be equal.

Proximal Precursor

Divide familiar shapes, such as circles, squares, and/or rectangles, into two or more equal parts.

Target

Identify the model that represents one half or one fourth of a familiar shape or object.

Successor

Identify the area model that is divided into halves or fourths.
