In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. TERMS Quantities - the amount (or number) of a thing Proportional relationship - relation of one dataset to another dataset Directly -...

In this shorts video we will answer a standardized math test question by comparing rates in miles per hour. We will read the information provided. We will determine the miles per hour from a graph. We will understand the graph shows a...

In this Grade 7 math video, we dive into how to determine if a table represents a proportional relationship between two quantities — a key skill aligned with standard 7.RP.A.2.



Students will analyze four real-world...

In this Grade 8 math video, we’ll solve a real-world problem using a unit rate described in words and four different graphs. Step by step, we’ll model how to write the unit rate as an ordered pair, graph the point, and determine which...

In this math video we will learn how to interpret, use and write an equation. We will review how an equation represents a real world relationship where y represents miles and x represents hours. We will also review that the coefficient...

In this math video lesson we will learn how to identify proportional relationships. Students will be able to identify whether a relationship is proportional between two quantities using bar diagrams.

Students will be able to...

A video entitled "Testing Graphing" which shows how to use a graph to test if ratios are proportional.
