Not all linear functions are linear transformations, only those that go through the origin. The third lesson in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at examples...

Equip young campers with the tips and strategies for a safe trip to the outdoors with a series of lessons. They learn how to start fires with and without firewood, keep warm in snowy weather, and purify water to make it safe for drinking.

Challenge the class to prove that the dilation properties always hold. The lesson develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member performing the...

Scholars learn to plot points on the coordinate plane. The lesson introduces the idea that the first coordinate of a coordinate pair represents the horizontal distance and the second coordinate represents the vertical distance. 

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it...

Use 2x2 matrices to move along a line. The second day of a two-day lesson is the 28th installment in a 32-part unit. Pupils work together to create and solve systems of equations that will map a transformation to a given...

Use the coordinate plane to show two figures are similar. The instructional activity incorporates congruence transformations and dilations to move a figure on to another figure. Pupils determine that if a similarity...

What's the best way to study? Well, it depends. . . Session two of a 23-lesson life skills series focuses on a variety of study skills strategies and suggests when/why to choose one over another.

Many indicators of health are beyond a teenager's control, but there are many changes they can make in their daily life that can improve their health. Middle schoolers think about their physical, social, and mental health status before...

It's time for a concept check! Check for student understanding over the three types of rigid transformations. The assessment follows the first 10 lessons in this series and to test pupils' proficiency of these concepts. Individuals...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Scholars learn how to find the distance of vertical and horizontal line segments on the coordinate plane in the 19th installment of a 21-part module. The use of absolute value comes in handy.

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

We can mathematically model the path of a robot. Learners use parametric equations to find the location of a robot at a given time. They compare the paths of multiple robots looking for parallel and perpendicular relationships and...

In this ancient Egypt worksheet, students read a 1-page selection about the civilization and examine a map of the region. Students outline the information that they read. 

Does the symmetry and transitive property apply to similarity? The 10th segment in a series of 16 presents the class with a group of explorations. The explorations have pairs show that similarity is both symmetrical and transitive....

Does it matter how many points to dilate? The resource presents problems of dilating curved figures. Class members find out that not only do they need to dilate several points but the points need to be distributed about the entire curve...

Use tree diagrams with multiple branches to calculate the probabilities of compound events. Pupils use tree diagrams to find the sample space for probability problems and use them to determine the probability of compound events in the...

Does the influence of interest groups harm a political system? Your class members will analyze the role of interest groups in American politics, as well as consider the effect of perspective, bias, loyalty, and the...

Here is a nice set of worksheets to get you started on teaching your young historians about the "Corrupt Bargain" in the presidential election of 1824, as well as the Tariff of 1828 and the emergence of new political parties.

In this European Union studies activity, learners examine governments in the United Kingdom and other European nations as they respond to 10 short answer questions and complete a graphic organizer.
