Evaluation for 5.4a
Materials provide opportunities for students to develop academic mathematical language using visuals, manipulatives, and other language development strategies.
The materials intentionally develop students’ academic mathematical language by integrating multiple visual representations, hands-on manipulatives, and structured language routines. In lesson 7.1, students analyze tables and graphs to identify independent and dependent quantities while using foam two-color counters to support their conceptual understanding. The lesson embeds the “Words to Learn” vocabulary routine to introduce and reinforce mathematical terminology and incorporates multiple “Mathematical Language Routines,” including “Three Reads,” “Discussion Supports,” “Collect and Display,” “Compare and Connect,” and “Critique, Correct, and Clarify.” The routines require students to engage in collaborative discussions, explain their reasoning using precise mathematical vocabulary, and connect visual representations with mathematical language throughout the lesson.
Additionally, in module 8, lesson 5, students use an area model to explain the distributive property and connect visual partitions to precise mathematical language. Guidance directs educators to provide a visual glossary with labeled partitions and arrows for
distribute,
expand, and
equivalent and then use “Turn and Talk” to have students explain how the area model shows the distributive property. If students need additional support, educators encourage them to trace parts of the model while naming the terms aloud. The tasks develop academic mathematical language through visuals, explicit connections between vocabulary and diagrams, and structured oral discourse.
The materials also provide educator guidance through the
Implementation Guide, which explains how educators can support students’ development of academic mathematical language through intentional instructional routines and language supports. For example, the “Language Growth for All Learners” section describes instructional strategies that help educators build mathematical vocabulary, scaffold academic conversations, and provide multiple opportunities for students to explain and justify their mathematical thinking using precise mathematical language during instruction.
