5 Gr 5_NF_FractionsMultiplication_Problem_Critique_HarvestingCorn

Posted on June 19, 2015August 22, 2015 by Tutita Casa

Harvesting Corn is a problem on fraction multiplication for fifth graders. Students are given the number of acres harvested and amount of days in a mixed number. The questions are scaffolded to require transformation of the mixed number to improper fraction, subtraction, and the final multiplication question that asks students to critique the thinking of a worker through argumentative language.

Posted on June 19, 2015August 22, 2015 by Tutita Casa

This task is created for fifth-grade students learning how to multiply fractions. Students are asked to critique the statement that half of a quarter is the same as a quarter of a half through multiple questions allowing for the problem to be visualized and broken down. A modification to the problem is presented to contain specific argumentation language, including as claim and evidence.

This is a task designed for fifth graders learning how to multiply mixed numbers. Students are asked to critique a student’s strategy to multiply mixed numbers, which ends up addressing a common misconception in multiplication of mixed numbers. Students must determine if adding the product of the whole numbers to the product of the fractions is equal to multiplying the two mixed numbers. Students are asked to decide if this is a rule that works, and explain their answer.

This task was used with 4th and 5th graders because it focused on multiplying fractions by whole numbers and converting common measurements. The main objective was to use a real world situation so that students would develop a deeper understanding of multiplying fractions by whole numbers as well as converting ounces and cups.

Posted on June 19, 2015August 22, 2015 by Tutita Casa

Filling up on Apples is a problem created for fifth graders on fraction addition and comparing fractions. In the task, two people eat multiple fraction amounts of apples and students are to use equivalent fractions and knowledge of fraction addition to determine how many apples were eaten. Scaffolding is used to break down the fractions and allow students to work on the problem one step at a time. Students are asked, through argumentation language, to critique the response on who ate more apples and show justification.

Posted on June 19, 2015August 3, 2015 by Tutita Casa

I used this task in my 5th grade classroom. It involves adding three fractions with unlike denominators. When the fractions are added, the sum is greater than one. The students also need to compare two mixed numbers to decide which mixed number is greater. The task requires them to decide who ate the most pie based on their comparison of two mixed numbers.

Stuffed with Pizza is a problem created for fifth graders on fraction addition. In the task, two people eat multiple fraction amounts of pizza and students are to use equivalent fractions and knowledge of fraction addition to determine how much pizza was eaten. Scaffolding is used to break down the fractions and lead up to the final question, which contains argumentative language as it asks students to critique the given response on who ate more pizza.

Posted on June 19, 2015August 22, 2015 by Tutita Casa

Lots of Pizza is a task in which fifth grade students must critique student responses to how much pizza was eaten by adding fractions of the whole. Students must be able to add three fractions with different denominators and determine if the value is equivalent to the addition of two fractions with different denominators. The task asks students to agree or disagree with student claims and explain reasoning.

Posted on June 19, 2015August 22, 2015 by Tutita Casa

Friends Who Run is a fraction addition problem designed for fifth grade. Students are given two people whose runs in a day are represented as fractions and are asked to mark distances on a number line, find the total number of miles run per person, and determine the difference between the two distances. Argumentation language is used, as well as scaffolding, to invoke the use of a claim and evidence in the critiquing the problem.

Posted on June 19, 2015August 22, 2015 by Tutita Casa

This task is designed for fifth graders working on fraction fluency. Students must know the vocabulary term “sum” and be able to add fractions, as they are asked to find the sum of two fractions with different denominators. Students must be able to determine if the fraction is closer to a half or whole by rounding, as well. Finding common denominators, creating equivalent fractions, and adding fractions are all skills necessary to complete this task. The problem allows space to solve as well as lines to justify a critique of student work.
