What's similar about congruent and similar polygons? Young mathematicians first measure the side lengths and angles of given figures. They use these measurements to determine relationships between side lengths and angles of congruent and...

Laws are meant to be broken, right? Learners derive the Law of Sines by dropping a perpendicular from one vertex to its opposite side. Using the Law of Sines, mathematicians solve for various parts of triangles.

What do a bunch of rhombuses, squares, and pentagons create? A snowman on a pattern block mat! Let young mathematicians explore shapes to create patterns in this hands-on activity worksheet.

Santa has his eye on you in a graphing activity that has young mathematicians plot ordered pairs on a Cartesian plane. After joining the points together, a picture of jolly Santa Claus comes to life.

Spruce up graphing practice with an activity that has young mathematicians plot points on a coordinate plane, and then connect the points to create a Christmas tree.

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Young mathematicians use photos and video clips to determine if a cricket player is "in" or "out." This analysis occurs using scale factors, distance-rate-time formula, and consideration of precision and accuracy.

Young environmentally conscious mathematicians solve a variety of problems related to the central theme of uncovering illegal logging activities. They determine a base camp based on given constraints, investigate logging activities and...

What would be a fair fare for a taxi? to answer the questions requires young mathematicians to analyze data on fuel prices and taxi cab fares. They determine and justify a fair fare price.

Challenge mathematicians to examine and sort a variety of 2-D and 3-D figures with a 10-problem solid shapes worksheet.

Explore the geometry of treasure hunting! Learners use geometry to design a treasure recovery strategy. The objective is to create a design that minimizes the amount of work required. Budding mathematicians use properties of triangles as...

Don't be a square! Help your budding mathematicians discover patterns within squares. Scholars create squares on geoboards and identify patterns in the number of nails, both nails on the edge of the squares and nails within the squares....

Future mathematicians use a given graph to answer a question about age differences in relationships. Along the way, they must find the equation and inequality of given graphs.

"Statistics are no substitute for judgment" - Henry Clay. Young mathematicians use provided statistics from a soda taste test to explain why conclusions are faulty. They devise a new test that would be more appropriate than the one given.

If you keep rolling a die, you'll roll a five exactly one-sixth of the time—right? A probability lesson prompts young mathematicians to roll a die 100 times and use the data to calculate empirical probabilities. They then compare...

Young mathematicians determine the number of hours it would take judges of the "Z Factor" television talent show to watch every act. Participants make estimates and assumptions to solve the problem.

Transform pupils into mathematicians as they create their own definitions and formulas. Scholars examine an assortment of triangles and create a definition and formula for determining the sharpness of the vertex angle. The groups of...

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.

Give the class a mental work out with an assessment task in which young mathematicians compare several gym membership options. They use substitution to calculate the cost for given numbers of months.
