Remarks
Examples of Opportunities for In-Depth FocusExtending fraction equivalence to the general case is necessary to extend arithmetic from whole numbers to fractions and decimals.
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.
- Assessment Limits :
Denominators of given fractions are limited to: 2, 3, 4, 5, 6, 8, 10, 12, 100. For items with denominators of 10 and 100, focus may not be on equivalence between these 2 denominators, since this is addressed specifically in standards MAFS.4.NF.5 – 7, but should focus on equivalence between fractions with denominators of 2, 4, and 5, and fractions with denominators of 10 and 100, e.g.,, etc.
Fractions must refer to the same whole, including in models. Fraction models are limited to number lines, rectangles, squares, and circles. Fractions
can be fractions greater than 1 and students may not be guided to put fractions in lowest terms or to simplify. Equivalent fractions also include fractions

Students partition squares to model two fractions and then determine if the fractions are equivalent.
Students draw a visual fraction model to determine whether two fractions are equivalent.
Students use a number line to explain that one-half is equivalent to two-fourths.
Students scale number lines to locate given fractions, find equivalent fractions, and explain the relationship between equivalent fractions.

Problem-Solving Tasks
The purpose of this task is to provide students with an opportunity to explain fraction equivalence through visual models in a particular example. Students will need more opportunities to think about fraction equivalence with different examples and models, but this task represents a good first step.
Type: Problem-Solving Task
The purpose of this task is for students to compare two fractions that arise in a context. Because the fractions are equal, students need to be able to explain how they know that. Some students might stop at the second-to-last picture and note that it looks like they ran the same distance, but the explanation is not yet complete at that point.

Illustrations that can be used for teaching and demonstrating fractions. Fractional representations are modeled in wedges of circles ("pieces of pie") and parts of polygons. There are also clipart images of numerical fractions, both proper and improper, from halves to twelfths. Fraction charts and fraction strips found in this collection can be used as manipulatives and are ready to print for classroom use.
