Reflection: Developing a Conceptual Understanding Partitioning Rectangles and Squares - Section 3: Guided Practice

 

As this lesson is students' first exposure to partitioning shapes, I chose to start by having students divide shapes using cubes.  Using cubes is a  very concrete way for students to partition their shapes.  I want my students to understand when they start drawing columns and rows that they are partitioning their shapes into smaller segments. In order for students to conceptually understand what partitioning  a shape means, I thought it would be useful for them to physically make columns and rows using their cubes. This tactic worked well and most students were able to quickly make the jump from arranging their cubes into columns and rows to simply drawing columns and rows on their shape.   The scaffold of using manipulatives was especially helpful for students who struggle to conceptually understand geometry, as well as students who struggle with visual-spatial reasoning.

Partitioning Rectangles and Squares

Unit 9: Partitioning Shapes
Lesson 1 of 8

Objective: SWBAT equally divide rectangles and squares into columns and rows.

Big Idea: In this lesson, students use cube manipulatives to equally explore partitioning of shapes.
