Clarifications:
Essential Understandings
Concrete:
- Use manipulatives and models (e.g., fraction bars and fraction circles) to add or subtract fractions with like denominators (2, 4, and 8; this is an expectation of students as referenced in MAFS.4.NF.2.AP.3b).
- Use visual representations of fractions to add or subtract.
- Using the line plot, add and subtract fractions with like denominators (1/2, 1/4, 1/8).

Cluster:
Represent and interpret data. (Supporting Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
