College Algebra with Professor Richard Delaware - UMKC VSI - Lecture 7 - Graphs. In this lecture we learn about the graphs of equations, intercepts, symmetry, and slopes. Great for Algebra 2 students or for parents who would like a College Algebra re...fresher.[more]

College Algebra with Professor Richard Delaware - University of Missouri Kansas City VSI - Lecture 2 - Language of mathematics. This Lecture gives an overview of the Language of Mathematics. Great for high school Algebra 2 students.

In this video, you will watch a class of 6th grade students discuss Problems 1 and 2 from the document “Are These Linear Functions?” The students have studied patterns for several weeks and have been introduced to plotting points on a graph from tabl...es of values generated from patterns problems. In this video, they have a first discussion about what the graphs for each problem might look like.[more]

College Algebra with Professor Richard Delaware - University of Missouri Kansas City. This video is the first in his lecture series that discusses set theory, types of sets, the break down theorems, real numbers, natural numbers. Great video for Alg...ebra 2 students in high school or college algebra students.[more]

College Algebra with Professor Richard Delaware - UMKC VSI - Lecture 8 - Graphs. This lecture gives an overview of equations of lines, parallel lines, perpendicular lines, and graphing a circle.

College Algebra with Professor Richard Delaware - UMKC VSI - Lecture 6 - Graphs. In this Lecture we learn about rectangular co-ordinates, midpoint and how to solve graphs on the graphing device.

In this 1:53 video students learn that how to use this method to help simplify their work. Easy to follow, but it moves very rapidly and so the video may need to be stopped to check student understanding.
