Evaluation for 4.3b
Materials provide interleaved practice opportunities with previously learned skills and concepts across learning pathways.
TheMath 180"Multiplication and Division Series Teaching Guide"provides a "Block at a Glance" for each block in aseries. The "Block at a Glance" is a visual map of the lessons within the threetopics, with an example of the strategy students are introduced to in each lesson. In grade 3, the mSpace lessons provide various strategies for multiplication, such as array models, area models, repeated addition, bar models, standardalgorithms, and equations. Through the learning progression, students learn more than one strategy to solve multiplication problems and engage in problem sets that require understanding word problems to plan whether to use an appropriate strategy.In the "Multiplication and Division Series," students use pictorial models to show the creation and separation of equal groups. As they build their understanding, these equal groups are later related to arrays and area models. When solving problems, students can choose any strategy.Students complete aCard Sortin eachseries, which provides interleaved practice. For example, in Card Sort:"Division," students are tasked with sorting and matching cards with different representations of multiplication and division. Students must determine which multiplication problems, division problems, and arrays match each other. This prompts students to solidify their understanding of multiplication and division as inverse operations, which will further allow students to use the two operations to solve problems.The "Multiplication and Division Series" encompasses TEKS 3.4g and 4.5a. 4.5a states that students will represent multi-step problems involving the four operations: addition, subtraction, multiplication, and division. For students to fulfill 4.5a satisfactorily, they must know how to multiply in a variety of ways, which was taught at the beginning of Block 1, and how to add and subtract, which is covered in the "Addition and Subtraction Series."
