The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.
This task requires students to recognize both "number of groups unknown" and "group size unknown" division problems in the context of a whole number divided by a unit fraction.
An application of fractions with ties to culinary careers and life skills in the upper elementary grades.
This applet allows the students to learn to multiply, add, simplify and convert fractions, decimals and percents by playing a game.
Grade 5s Module 4 extends student understanding of fraction operations to multiplication and division of both fractions and decimal fractions. Work proceeds from interpretation of line plots which include fractional measurements to interpreting fractions as division and reasoning about finding fractions of sets through fraction by whole number multiplication. The module proceeds to fraction by fraction multiplication in both fraction and decimal forms. An understanding of multiplication as scaling and multiplication by n/n as multiplication by 1 allows students to reason about products and convert fractions to decimals and vice versa. Students are introduced to the work of division with fractions and decimal fractions. Division cases are limited to division of whole numbers by unit fractions and unit fractions by whole numbers. Decimal fraction divisors are introduced and equivalent fraction and place value thinking allow student to reason about the size of quotients, calculate quotients and sensibly place decimals in quotients. Throughout the module students are asked to reason about these important concepts by interpreting numerical expressions which include fraction and decimal operations and by persevering in solving real-world, multistep problems which include all fraction operations supported by the use of tape diagrams.

Nice task that challenge students to think about and represent factions.
This task provides a context for performing division of a whole number by a unit fraction. This problem is a "How many groups?'' example of division.

Módulo 4 de grado 5 extiende la comprensión del estudiante de las operaciones de fracción a la multiplicación y la división de fracciones y fracciones decimales. El trabajo procede de la interpretación de los gráficos de línea que incluyen mediciones fraccionales para interpretar las fracciones como división y razonamiento sobre la búsqueda de fracciones de conjuntos a través de la fracción por multiplicación de números enteros. El módulo procede a la fracción por multiplicación de fracción en formas de fracción y decimal. Una comprensión de la multiplicación como escala y multiplicación por N/N como multiplicación por 1 permite a los estudiantes razonar sobre productos y convertir fracciones en decimales y viceversa. Los estudiantes son presentados al trabajo de división con fracciones y fracciones decimales. Los casos de división se limitan a la división de números enteros por fracciones unitarias y fracciones unitarias por números enteros. Se introducen divisores de fracción decimal y la fracción equivalente y el pensamiento del valor del lugar permiten al alumno razonar sobre el tamaño de los cocientes, calcular los cocientes y colocar decimales con sensatez en los cocientes. A lo largo del módulo, se les pide a los estudiantes que razonen sobre estos conceptos importantes interpretando expresiones numéricas que incluyen operaciones de fracción y decimales y perseverar en la resolución de problemas de varios pasos en el mundo real que incluyen todas las operaciones de fracción compatibles con el uso de diagramas de cintas.

The purpose of this task is for students to find the answer to a question in context that can be represented by fraction multiplication. This task is appropriate for either instruction or assessment depending on how it is used and where students are in their understanding of fraction multiplication.
This mobile app (available for both iOS and Android devices) was developed by the National Council of Teachers of Mathematics with funding from Verizon Foundation. The app is based on the Decimal Maze from the popular lesson "Too Big or Too Small". The goal is to help Okta reach the target (maximum, minimum, or a specific value) by choosing a path from the top of the maze to the bottom — adding, subtracting, multiplying and dividing as the player goes. Seven levels with seven puzzles in each level test the player's skills with operation with powers of ten, negative numbers, fractions, decimals, and exponents.
How many orange wedges are in the bowl? Through the use of photographs and videos, students are challenged to determine exactly how many orange slices are in the bowl.
