CC.4.NF.1 Extend understanding of fraction equivalence and ordering.
Read the Fine Print
Rating
0.0 stars

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. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)

Grade 4 Module 5: Fraction Equivalence, Ordering, and Operations

0.0 stars

In this 40-day module, students build on their Grade 3 work with unit fractions as they explore fraction equivalence and extend this understanding to mixed numbers.  This leads to the comparison of fractions and mixed numbers and the representation of both in a variety of models.  Benchmark fractions play an important part in students’ ability to generalize and reason about relative fraction and mixed number sizes.  Students then have the opportunity to apply what they know to be true for whole number operations to the new concepts of fraction and mixed number operations.

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.

La descripción original en inglés también se proporciona a continuación.)

En el módulo 3, la comprensión de los estudiantes de la adición y la resta de las fracciones se extiende desde el trabajo anterior con equivalencia de fracción y decimales. Este módulo marca un cambio significativo lejos de la centralidad de los grados elementales de las diez unidades de base al estudio y el uso del conjunto completo de unidades fraccionarias desde el avance de grado 5, especialmente como se aplica al álgebra.

Esto lleva a la comparación de fracciones y números mixtos y a la representación de ambos en una variedad de modelos. Las fracciones de referencia juegan un papel importante en la capacidad de los estudiantes para generalizar y razonar sobre la fracción relativa y los tamaños de números mixtos. Luego, los estudiantes tienen la oportunidad de aplicar lo que saben para ser cierto para las operaciones de números enteros a los nuevos conceptos de fracción y operaciones de números mixtos.
