Khan Academy: Measuring Rectangles With Different Unit Squares

Sal uses different units, standard and non-standard, to measure the same object. Includes a video, transcript, and question and answer section. [2:53]

In this video lesson, Sal uses different units to measure the same object, centimeters and rectangles.

In this lesson, students units use different units to measure the same object.

Models how to find the area of a shape on a grid that has different angle sizes by counting both square and partial units. [3:16]

Count unit squares and partial unit squares to find the area of shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive step-by-step hints.
