Divisibility and Factors

When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

Be sure to look both ways when making a two-way table. In the lesson, scholars learn to create two-way tables to display bivariate data. They calculate relative frequencies to answer questions of interest in the 14th part of the series.

Increase understanding of the algebraic properties and their importance. Scholars justify their steps as they simplify expressions and solve equations. They formalize their work as two-column proof.

Here is an introduction to solving simultaneous linear equations. Start by drawing a line through two points. Create a second line which goes through the intersecting point. Background knowledge of how to find the equation of a line and...

Determine whether there is a difference between two grades. Teams generate random samples of two grade levels of individuals. Groups use the mean absolute deviation to determine whether there is a meaningful difference between the...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Oh no, there are decimals! A resource shows a method to solve a two-step equation that contains decimals. Using a process of clearing the decimals, the presenter converts the equation into a basic two-step equation with whole numbers. At...

Solving equations is as easy as 1-2-3. Using two examples, the video shows the order of the steps to use when solving a two-step equation. It uses a vertical approach to perform the inverse operations to isolate the variable. To finish,...

Two vehicles move at a constant rate of speed toward each other, but when exactly will they pass? Pupils use still images from a video to determine the rate of speed and when the two cars meet. Then, they watch the complete video to...

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a two step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...
