Materials include embedded guidance to support student application of appropriate mathematical language and academic vocabulary in discourse.
The materials include embedded teacher-facing supports that guide the application of academic mathematical vocabulary during structured discourse. In Mission 1, Lesson 9, the teacher materials prompt the use of terms such asrow,array,number of groups,size of group,product, andarea model, to describe multiplication strategies and compare groupings. Prompts in the "Lesson Synthesis" section include "How does the array help find the total?" and "What does the size of the group represent in this model?" to reinforce vocabulary through discussion and written explanation. In Mission 1, Lesson 3, the "Concept Exploration" and "Guided Practice" sections provide prompts that support using terms such asrepeated addition,unit form, andmultiplication, during problem-solving tasks like 3 × 2 = 6. Sample teacher questions include "Can the total be described using repeated addition?" and "How does the unit form support writing the multiplication sentence?" to guide structured mathematical discourse. In Mission 7, Lesson 5, the "Math Chat" and "Student Discussion" sections include structured prompts to support vocabulary use in financial contexts. The teacher materials present labeled visuals and questions, such as "What is meant by high demand and low supply?" and "How does this strip diagram explain the price difference?" to guide the use of terms likesupply,demand,price, andvalue, during the analysis of economic scenarios.
