Materials demonstrate coherence vertically across concepts and grade bands, including connections from grades 3–12, by connecting patterns, big ideas, and relationships.
The Imagine+ Math program demonstrates coherence vertically across concepts and grade bands by connecting patterns, big ideas, and mathematical relationships across grades 3-12. For example, the grade 6 “Expressions, Equations, and Relationships” unit builds on students’ prior experiences with numerical patterns, operations, and problem-solving from grades 4 and 5, where students analyze numerical patterns, evaluate numerical expressions, and solve problems involving the four operations with whole numbers, fractions, and decimals. Building on this foundation, grade 6 students transition from arithmetic reasoning to algebraic thinking by writing, interpreting, and evaluating algebraic expressions, applying the order of operations and the distributive, associative, and commutative properties to generate equivalent expressions. Students also move from solving numerical problems to representing relationships with variables, equations, and inequalities, using models, algebra tiles, and balance-scale representations to connect concrete and visual understandings developed in earlier grades to abstract algebraic representations. These activities prepare students for more advanced algebraic concepts in later grades.
The materials demonstrate coherence vertically across concepts and grade bands and make connections from grades 3–12 by connecting patterns, big ideas, and relationships. The materials include a “Vertical Concept Map” that identifies explicit connections to prior knowledge and future mathematical concepts, supporting vertical coherence across grade levels aligned to the TEKS. For example, in grade 6, students begin formal work with ratios and rates, building on earlier multiplicative reasoning, representing ratios using models, tables, and graphs, and solving problems involving equivalent ratios. Unit concepts extend into rates and unit rates, including proportional relationships in real-world contexts such as recipes, maps, and speed, promoting an understanding of proportionality that is foundational for later study of slope and linear functions. The
Teacher Guide includes reflection questions asking how a problem connects to prior learning and why the problem matters in mathematics, prompting students to make connections across their developing understanding.
