This Nrich activity is an unusual context in which pupils can consolidate recognizing, finding, naming and writing fractions. The rich environment also gives them the opportunity to identify, name and write equivalent fractions of a given fraction, represented visually as a chain. Furthermore, learners will be adding and subtracting fractions with the same denominators and denominators which are multiples of the same number.

The purpose of this instructional task is to motivate a discussion about adding fractions and the meaning of the common denominator. The different parts of the task have students moving back and forth between the abstract representation of the fractions and the meaning of the fractions in the context.

UMCDC 5th Grade Engage NY Math Module 3 Topic B (20-21) In Topic B, students use the familiar rectangular fraction model to add and subtract fractions with unlike denominators. Students make like units for all addends or both minuend and subtrahend. First, they draw a wide rectangle and partition it with vertical lines as they would a tape diagram, representing the first fraction with a bracket and shading. They then partition a second congruent rectangle with horizontal lines to show the second fraction. Next, they partition both rectangles with matching lines to create like units.

UMCDC 5th Grade Engage NY Math Module 3 Topic C (20-21) In Topic C, students use the number line when adding and subtracting fractions greater than or equal to 1. The number line helps students see that fractions are analogous to whole numbers. The number line makes it clear that numbers on the left are smaller than numbers on the right, which leads to an understanding of integers in Grade 6. Using this tool, students recognize and manipulate fractions in relation to larger whole numbers and to each other. For example, “Between which two whole numbers does the sum of 1 2 3 and 5 3 4 lie?”

UMCDC 5th Grade Engage NY Math Module 3 Topic D (20-21) Topic D opens with students estimating the value of expressions involving sums and differences with fractions. “Will your sum be less than or greater than one half? One? How do you know?” Though these conversations have been embedded within almost every Student Debrief up to this point, by setting aside an instructional day to dig deeply into logical arguments, students see that it is very easy to forget to make sense of numbers when calculating. This is really the theme of this topic—reasoning while using fractions.

UMCDC 5th Grade Engage NY Math Module 3 (20-21) In Module 3, students’ understanding of addition and subtraction of fractions extends from earlier work with fraction equivalence and decimals. This module marks a significant shift away from the elementary grades’ centrality of base ten units to the study and use of the full set of fractional units from Grade 5 forward, especially as applied to algebra.
