 Welcome to “Math Studio Talk” a video series that provides games, activities and models to help students develop flexible thinking and deep understanding of math concepts from kindergarten to Grade 5...

 Objective: Represent equal groups with tape diagrams, and relate to repeated addition.

 Topic C naturally follows Topic B, where students composed and manipulated the rows and columns of an array. This topic is designed to deepen students’ understanding of spatial structuring as they...

 Topic B focuses on spatial relationships and structuring as students organize equal groups (from Topic A) into rectangular arrays. They build small arrays (up to 5 by 5) and use repeated addition of...

 Topic A begins at the concrete level as students use objects to create equal groups, providing a foundation for the construction of arrays in Topic B. In Lesson 1, for example, students are given 12...

 Objective: Use square tiles to compose a rectangle, and relate to the array model.

 Objective: Use square tiles to compose a rectangle, and relate to the array model.

 Objective: Solve word problems involving addition of equal groups in rows and columns.

 Objective: Create arrays using square tiles with gaps.

 Objective: Represent arrays and distinguish rows and columns using math drawings.

 Objective: Decompose arrays into rows and columns, and relate to repeated addition.

 Objective: Compose arrays from rows and columns, and count to find the total using objects.

 Objective: Use math drawings to represent equal groups, and relate to repeated addition.
