Maps Scales
For I have miles to go before I truly understand map scales. By watching a video, scholars learn about map scales. They see how to determine actual distances on a map using the scale and how to calculate the map scale.

Enlargements with Fractional Scale Factors
Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...
