Evaluation for 5.3c
Materials include supports for students in connecting, creating, defining, and explaining concrete and representational models to abstract (symbolic/numeric/algorithmic) concepts, as required by the TEKS.
The Math Journeys grade 5 Spanish program contains explicit, structured opportunities for students to connect, create, define, and explain both concrete and representational models leading to abstract concepts, as required by the TEKS. For example, during the warm-up, students independently analyze a pictorial representation of dollar bills and coins, assigning the correct place value to each to determine a total decimal value. Using process standard 1F in the development activity, the educator prompts students to explain the structural relationship between the money model and the decimal place-value system by asking, “How are the relationships between dollars, dimes, and pennies similar to the relationships between hundreds, tens, and ones?” and “Could you explain why we need to regroup when the number of cents in the subtrahend is greater than in the minuend?” The curriculum then helps students transition to representational models by requiring them to actively cross out subtrahend values and draw how whole bills are regrouped into 10 separate dimes, rather than simply viewing a completed static image.
The Math Journeys grade 5 Spanish curriculum contains explicit, structured opportunities for students to connect, create, define, and explain both concrete and representational models leading to abstract concepts, as required by the TEKS. For example, students connect concrete models, such as fraction pieces and manipulatives, and representational models, such as visual fraction diagrams, to abstract fraction operations by linking models to equivalent fractions and common denominators. Students create models by building and manipulating fraction pieces and visual representations to transform and combine fractions, developing a hands-on foundation for abstract understanding. The lesson further helps students define and clarify their reasoning by requiring them to justify why fractions must share a common denominator, explain equivalence through multiplying by one, and connect these ideas to symbolic procedures. By consistently engaging students in connecting, creating, and explaining across all three representations throughout a given lesson, the curriculum fully addresses all components of the indicator.
