What we like about this task

Mathematically:

• Addresses standards: 3.NF.A.3d and MP.3
• Presents two fractions with the same numerator so that students can compare the size of an area that is 2 one-third sections with an area that is 2 one-fifth sections
• Requires student to recognize that two fractions must refer to the same whole in order to be compared (3.NF.A.3d)
• Builds on student understanding of non-unit fractions as multiple parts of unit fractions (3.NF.A.1)
• Uses rectangular fraction models, which can lead to understanding of fractions on the number line, showing coherence within the 3.NF standards

In the classroom:

• Uses concrete representation to make the mathematics explicit
• Can lead to related discussions with the other fraction comparison tasks
• Presents a task in an assessment-ready form, that is also easily implemented in the classroom

This task was designed to include specific features that support access for all students and align to best practice for English Language Learner (ELL) instruction. Go here to learn more about the research behind these supports. This lesson aligns to ELL best practice in the following ways:

• Provides opportunities for students to practice and refine their use of mathematical language.
• Allows for whole class, small group, and paired discussion for the purpose of practicing with mathematical concepts and language.
• Elicits evidence of thinking both verbally and in written form.
• Includes a mathematical routine that reflects best practices to supporting ELLs in accessing mathematical concepts.
• Provides opportunities to support students in connecting mathematical language with mathematical representations.
