Overview

In this performance assessment, students will use their knowledge of simple equivalent fractions and be able to explain why they are equivalent using number lines or other models. Specifically, students will be asked to complete a performance task that will check their mastery of these skills.

Big Ideas & Competencies

Big Ideas Competencies

A. Understanding and Applying Number Systems

Students understand that numbers hold value and can choose the appropriate representations and algorithms to reason quantitatively, abstractly, and efficiently.

Equivalent Fractions 1

Students can generate simple equivalent fractions and explain why the fractions are equivalent, using number lines and other models.

NOTE ABOUT ASSESSMENT RUBRICS

Below are analytic teacher rubrics. The column on the left shows the dimension that is being measured in the student’s performance. The levels across the top row indicate the performance level in the dimensions. Occasionally all dimensions and performance levels are exemplified by multiple students in a single recording.

Reading and Explaining

  • I can attempt to generate equivalent fractions and prove they are equivalent using models, but the fractions are not equivalent, or my models demonstrate an incomplete understanding of equivalent fractions. 
No exemplars at this time.
  • I can generate equivalent fractions and use at least two different types of models to prove their equivalency, but my models are poorly partitioned and/or difficult to read.
No exemplars at this time.
  • I can generate equivalent fractions and use three different types of models to prove their equivalency, and my models are neat, accurately partitioned, and easy to read. 
No exemplars at this time.
