Young mathematicians demonstrate their ability to subtract mixed numbers by completing this collection of fraction word problems. From figuring out the weight of objects in a package, to finding the difference in height between two...

Geometric volume calculations are brought into the real world in a quick set of application problems. Learners are asked to help a patient figure out how to drink a prescribed amount of water both at work and at home. This activity...

Everything you could possibly want to know about quadratic equations, all in one resource. Instructors demonstrate how to translate between different forms of quadratics (equation, table of values, graph, verbal description) and finding...

Sometimes, the best solution to a problem can be found by walking in someone else's shoes. Here, scholars use character cards to take on the roles of people around the world. They determine how their character's...

Connect division with multiplication through the use of models. Groups solve problems involving the division of a whole number by a fraction using models. The groups share their methods along with the corresponding division and...

Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

Introduce teens to the teamwork skills and habits of mind they need to be successful in 21st century classrooms and in the workplace with the activities based on Sean Covey's The Seven Habits of Highly Effective Teens.

Relevance is key! The resource applies quadratic modeling by incorporating application of physics and business. Pupils work through scenarios of projectile motion and revenue/profit relationships. By using the key features of the graph,...

Conduct research focused on improving a current technology by having students work in groups to investigate improvements that could be made to a particular piece of technology. They list the current problems and attempt to develop...

Right angles, acute angles, obtuse angles, central angles, inscribed angles: how many types of angles are there? Learners first investigate definitions of inscribed angles, central angles, and intercepted arcs. The majority of the...

Represent the relationship between independent and dependent variables through a modeling situation. The activity expects learners to graph the volume of water in a bathtub during a given scenario. The graph should result in two areas of...

Build on your classes' understanding of irrational numbers by comparing their values. The 13th instructional activity in the 25-part module has individuals estimate values of both perfect and non-perfect roots. They finish by graphing...

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...

It is all about being equivalent. Class members convert between fractions, decimals, and percents. By using visual models, scholars verify their conversions in the 25th portion of a 29-part series.

What are the factors that limit growth and expansion? As part of their study of Catalina Island, class members view the West of the West's documentary Magic Isle and research William Wrigley and the Santa Catalina Island Company. After...

Learners review how to use the completing-the-square method to identify maximum and minimum values of a quadratic function by watching a video. They see how the vertex form relates to the extreme values of a quadratic function, and use...

Young mathematicians compare the growth of two snake lengths in feet over one year in a straightforward word-problem task.

DNA writes 64 different words but only codes for 20 different amino acids. Budding scientists learn about where each of these numbers come from and why they aren't equal with an online interactive. The resource explains the research, the...

Teach your young readers how to summarize a text using a strategy called Somebody Wanted But So. Kids identify the character (Somebody), the motivation (Wanted), the conflict (But), and the resolution (So). The resource comes with...

The world may indeed be a stage, and players certainly need to know drama vocabulary. This list of 16 terms (and their definitions) often found in scripts will prompt actors to perform their role.

Don't go off on a tangent while writing equations of tangent lines! Scholars determine the equations for tangent lines to circles. They attempt both concrete and abstract examples, such as a tangent line to the unit circle through...

Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...
