Evaluation for 5.4a
Materials provide opportunities for students to develop academic mathematical language using visuals, manipulatives, or other language development strategies.
The materials embed academic vocabulary throughout lesson tasks, prompting students to apply precise mathematical language to describe models, operations, and quantities. For example, in "Use models to add three-digit numbers without regrouping," students interpret visual representations of base-ten blocks labeled "The blocks show 312 + 141," then complete prompts identifying the "hundreds, tens, and ones," followed by the full addition sentence.The materials provide multiple opportunities for students to develop and apply language strategies while solving problems and explaining reasoning. For example, in "Use models to add two-digit numbers no regrouping," digital base-ten blocks accompany sentence frames such as, "I combined 30 and 40 to make 70, then added 2 + 3 = 5, so the total is 75," reinforcing vocabulary like "combine and total."The materials include visual models, vocabulary supports, and collaborative tasks to build mathematical language. For example, in the lesson on identifying angles and attributes of two-dimensional shapes, students count sides, vertices, and angles, and then compare shapes with a partner using terms likesides,vertices, andangles. Suggested supports include anchor charts to reinforce key vocabulary.
