Evaluation for 3.2a
Materials include explicit (direct) prompts and guidance for educators to build knowledge by activating prior knowledge, anchoring big ideas, and highlighting and connecting key patterns, features, and relationships through multiple means of representation.
The “Building the Foundation” section includes educator guidance for activating prior knowledge and anchoring big ideas through connections to prerequisite skills and educator-directed instructional strategies within lessons. This section supports educators in helping students build foundational understanding before new learning.
The program equips educators with explicit prompts and guidance to build knowledge by activating prior knowledge and anchoring big ideas. Unit overviews establish this framework by connecting prerequisite understanding to new mathematical concepts: Each unit opens with an overview that anchors the unit’s big idea—for example, unit 2, “Algebraic Reasoning,” frames numeric patterns and relationships as the foundation for representing expressions, equations, and coordinate-plane relationships symbolically—followed by “Vocabulary Development,” which distinguishes new grade-level terms from previously introduced ones. Within each lesson, “Building the Foundation” gives educators targeted scaffolds addressing prerequisite concepts and skills for students who need additional help before or after instruction, and “Coherence and Connections” highlights connections between prior knowledge and current grade-level concepts. “Practice for Long-Term Learning” further activates prior knowledge through brief, spiraled retrieval prompts that revisit previously taught standards throughout the year.
Imagine+ Math highlights and connects key patterns, features, and relationships through multiple means of representation. In unit 2, “Algebraic Reasoning,” the Coordinate Toss fluency activity connects a numeric pattern across multiple representations: Students roll dice to generate an ordered pair, plot the resulting point on a coordinate grid, and compare their points to those of classmates to identify patterns, such as points sharing the same
x-value forming a vertical line. In unit 1, “Number and Operations,” the Decimal Compare fluency activity connects the relationship between two decimal quantities across multiple representations: Students draw number cards to build a decimal, compare their decimal to a partner’s to determine which is greater, and explain their reasoning verbally using place-value language. In unit 3, “Geometry and Measurement,” the Volume Build fluency activity connects the defining feature of a rectangular prism’s volume across concrete and symbolic representations: Students build a rectangular prism out of cubes, count the cubes to find the volume directly, then measure the prism’s side lengths and calculate volume using the formula
V =
l ×
w ×
h, comparing the two methods to confirm they produce the same result.
