Topic

Volume

Description

The image shows a rectangular prism made up of 3 unit cubes arranged in a single row. The example asks for the volume of the figure, and the solution involves counting the number of unit cubes. Example 1: The figure consists of 3 unit cubes. The caption reads: "Count the number of unit cubes to find the volume. 3 unit cubes means that the volume is 3."

Topic

Volume

Description

The image shows a figure made up of 4 unit cubes, with one cube stacked on top of another, forming an L-shape. The example asks for the volume, and the solution involves counting the cubes. Example 2: The figure consists of 4 unit cubes. The caption reads: "Count the number of unit cubes to find the volume. 4 unit cubes means that the volume is 4."

Topic

Volume

Description

The image shows a figure made up of 5 unit cubes arranged in an irregular shape, with one cube raised above others. The example asks for the volume, and the solution involves counting the number of unit cubes. Example 3: The figure consists of 5 unit cubes. The caption reads: "Count the number of unit cubes to find the volume. 5 unit cubes means that the volume is 5."

Topic

Fractions

Description

The image shows a rectangular prism made up of 6 unit cubes arranged in two layers (a top and bottom row). The example asks for the volume, and the solution involves counting all the cubes in both layers. Example 4: The figure consists of 6 unit cubes. The caption reads: "Count the number of unit cubes to find the volume. 6 unit cubes means that the volume is 6."

Fractions

Description

The image shows a 3D figure made up of unit cubes. The figure is stacked in a staggered manner, with some cubes placed directly on top of others. Below the figure, there is a breakdown showing the individual cubes counted to determine the volume. Example 5: The caption asks for the volume of the figure, which is made up of unit cubes. The solution involves counting the cubes to find the volume.

In this program, internationally acclaimed mathematics educator Dr. Monica Neagoy, explores the nature of linear functions through the use TI graphing calculators. Examples ranging from air travel, construction, engineering, and space travel provide real-world examples for discovering algebraic concepts. All examples are solved algebraically and then reinforced through the use of the TI-Nspire. Algebra teachers looking to integrate hand-held technology and visual media into their instruction will benefit greatly from this series. Concepts explored: Standard form, slope-intercept form, point-slope form, solving linear equations Note: The download for this resources is the Promethean Flipchart.
