Posted on by

Running a Race is a task designed for fourth graders working on multiplying fractions by a whole number. The task is an application problem that asks students to compare which answer will be larger. Skills necessary to complete this task sufficiently may include multiplying a fraction by a whole number, finding common denominators, and comparing fractions. Students are asked to make a claim and support it with an explanation.

Lemonade is a task for fourth-grade students learning how to multiply fractions, specifically a mixed number in this problem. Two responses are given as to how many lemons are needed, but no work is shown as to how an answer was determined. Through argumentative language, students are asked to critique given responses, provide evidence, and explain their thinking.

Posted on by

Agreeing or Disagreeing with Sally is a task designed for fourth graders working on fraction fluency. Students are asked to compare two fractions with different numerators and different denominators. Students must critique an argument that states that two fractions are equivalent by agreeing or disagreeing and explaining the decision. The task will also allow students to demonstrate ability to create equivalent fractions.

Posted on by

Running Out of Gasoline is task designed for fourth graders comprehending how to compare fractions. Students are given the amount of gas left in two different car tanks as a fraction with different numerators and denominators. The task is scaffolded through multiple questions that contain argumentative language asking the students to break apart the fractions, use equivalent fractions, and ultimately critique a response and provide justification.

I used this task in the beginning of the school year with 6th graders who were struggling with fractions. I had 2 main objectives for this task. One was to give students more practice with equivalent fractions, and two was to introduce the Talk Frame to the students.

Posted on by

This task asks fourth grade students to critique a student’s comparison of two fractions. The task asks student to agree or disagree and provide an expanation. Students must compare fractions with different denominators. This addresses the common error of students only looking at the numerators and comparing them. The task may also require students to create equivalent fractions by finding common denominators in order to compare the fractions.

We used this task to teach teachers about how to use a Talk Frame in their instruction to begin lessons that support argumentation. The main objective was to develop teachers’ understanding of how to use the Talk Frame in order to give students the opportunity to first work independently, then as a group, then for groups to present 3 distinct approaches/strategies to problem solving and finally to critique each other’s mathematical argument. This task required teachers to experience participating in a Talk Frame from the lens of the student. They needed to work with their groups to select a strategy, provide evidence of how the strategy got them to their solution, and finally to come away with some understandings either about Talk Frames or around the actual content of the problem.
