Evaluation for 5.4b
Materials include embedded educator guidance to scaffold, support, and extend students’ use of academic mathematical vocabulary in context when communicating with peers and educators.
The materials embed educator guidance to scaffold and extend the use of academic mathematical vocabulary in lesson discussions. In Mission 1, Lesson 5, during the "Multiple Means of Representation" section, students trace groups of objects in arrays using fingers or colored pencils while repeating the terms array and row. Teachers prompt students to describe their visual models using these terms in partner discussions and journal reflections. Lesson guidance supports structured oral language practice, reinforcing accuracy through repetition and peer explanation.The materials provide multimodal support for vocabulary development using gestures, diagrams, and teacher-facilitated discussion. In Mission 2, Lesson 3, teacher materials explicitly instruct educators to model the gesture for area by outlining the surface of a rectangle, linking language to visual structure. In the "Concept Exploration" section, students use strip diagrams and equations to describe multiplicative comparisons using terms such as factor, product, and times as many. Guided questions such as "How does this diagram show a comparison?" and "What are the factors in your equation?" extend academic vocabulary in mathematical reasoning.The materials integrate explicit vocabulary instruction into real-world financial contexts. In Mission 6, Lesson 4, during "Math Chat" and "Guided Practice," labeled visuals introduce coin names, including quarter, dime, nickel, and penny. Teachers use prompts like "What do we mean by more expensive and less expensive?" and "How does the strip diagram show the change in cost?" to guide students in applying content-specific vocabulary such asprice,value,cost, andchange. Lesson guidance supports language development by connecting mathematical terms to meaningful scenarios and encouraging students to justify relationships using precise language.
