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 materials include supports for students in connecting and creating concrete models to abstract mathematical concepts, as required by the TEKS. For example, in Lesson 9-6: "Connect Multiplication to Area," students build models of rectangles with unit squares and then solve additional problems using the formula for area, as required in TEKS 3.6D, "determine the area of rectangles . . .using multiplication related to the number of rows times the number of unit squares in each row formulas for area." The materials include supports for students in connecting and creating representational models to abstract (symbolic/numeric/algorithmic) concepts, as required by the TEKS. For example, Lesson 4-7: "Multiply Decimals Using Partial Products," students use arrays, area models, and the multiplication algorithm to solve problems, as required by TEKS 5.3D, "represent multiplication of decimals with products to the hundredths using objects and pictorial models, including area models." The materials include supports for students in defining and explaining concrete models to abstract (symbolic/numeric/algorithmic) concepts, as required by the TEKS. For example, in Lesson 9-1: "Multiplying with Fractions" the student solves problems with an emphasis option to use counters or fraction strips, as well as tables to fully understand the concept of multiplying fractions, as required in TEKS 5.3I, "represent and solve multiplication of a whole number and a fraction that refers to the same whole using objects and pictorial models, including area models." The materials include supports for students in defining and explaining representational models to abstract (symbolic/numeric/algorithmic) concepts, as required by the TEKS. For example, in Lesson 6-5: "Dividing Decimals," students solve problems with grid paper, area models, and calculations to understand decimal division, as required in TEKS 5.3F and G, "represent quotients of decimals. . .using objects and pictorial model," and "solve for quotients of decimals using strategies and algorithms."
