## Visualizing Two Variable Linear and Non-Linear Relationships

Tables of Values, Graphing Scatter Plots, Describing Relationships and Making Predictions Although generally not the urgent student learning need in most classrooms, working with two-variable linear and non-linear relationships could also be made more visual to help students better understand some of the important pieces that will help with linear equations and beyond. As mentioned in posts pr...

## Visualizing the Maximum Area of a 3-Sided Rectangular Enclosure

Increasing Spatial Reasoning Skills: Optimization of Measurement Although maximizing the area of a 4-sided rectangular enclosure is usually considered quite basic for most students, understanding why maximizing a 3-sided rectangular enclosure does not yield a square can be more difficult. To help address this student learning need, here is the animation created for maximizing the area o...

## Visualizing the Maximum Area of a 4-Sided Rectangular Enclosure

Increasing Spatial Reasoning Skills: Optimization of Measurement In the past, when introducing the concept of Optimization of Measurement, students would complete a series of investigations involving different lengths of rope, fence, etc. and would make connections from the table of values and graph they would produce. While I still intend to do some of the investigations, I want to make...

## Visualizing the Area of a Trapezoid Formula

Visually Understanding Area of a Trapezoid in Multiple Ways While some students are aware that they could find the area of a trapezoid by treating the shape like a composite figure, I wanted to help students better understand where the formula comes from with a visual aid. Here is the next video animation I created in my Visualizing Mathematics series: Visualizing the Area of a Trapezoid ...

## Visualizing the Volume of a Triangular Prism Formula

Visually Understanding Area of a Triangle and Volume of a Triangular Prism About a week ago, I shared my visual animations explaining the "Derivation of the Volume of a Cylinder Formula" and Volume of a Rectangular Prism formula I used in class and students seemed to be able to tie some of the visuals to the work they completed in class. Here is the next video animation I created in my Vis...
