Students define reflection, rotation and symmetry. In this symmetry lesson plan, students move the graph around the coordinate plane and identify the line of symmetry. They identify the different designs of a kaleidoscope.

Students identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Students untie knots and relate it to math. In this algebra lesson, students explore the history of knot tying. The tie their own knots and untie the knots using ropes.

Students explore the cost of wasted water. In this math lesson, students conduct an experiment in which they collect data on how much water is lost when a faucet leaks. Students figure the cost of the water that was wasted.

Students figure the best gas prices. In this math instructional activity, students add and multiply with decimals. Students complete a worksheet to find which supplier offers the best gas prices.

Students explore transformations. In this math lesson, students plot points on a coordinate grid and construct shapes. Students discuss movements on the grid as flips, turns and slides.

Students explore the cost of a party. In this math lesson plan, students plan a party and determine the cost of hosting a party. Students use information from grocery stores to determine the unit cost of items for the party.

Students explore mean, median and mode. In this math lesson plan, students analyze temperature data and figure the mean, median, and mode of the data. Students graph the data in a bar graph.

Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

Students calculate the speed, motion and distance of a projectile. In this geometry lesson, students obtain measurements while calculating velocity. They graph their results and make predictions.

Students calculate the distance and velocity over time. In this algebra lesson plan, students graph a linear function to represent the distance vers time travel. They interpret their graphs and draw conclusion.

Ninth graders explore the specific reaction between an antigen and the antibody that recognizes it. They carry out an exploratory experiment leading to the concept of specificity.

Learners use the Internet to delve into the relationship between fores and motion on a sizable object. They predict where they think the temperature and pressure be the greatest, and where the pressure be the lowest.

Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.

Students practice multiplying and dividing fractions by doubling, halving, tripling, etc., recipes from a cookbook.

Students compare different aspects of investing money from traditional savings accounts to money market accounts. They research investment accounts at local banks and compare them.

High schoolers complete a unit focusing on the creation of a student-generated website. They read and evaluate articles about business ethics, critique websites, and develop a student-created webpage.

Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.

Learners discuss comparing the size of two different sets of blocks. They estimate the length of the long blocks by answering the following questions: How can you use the small blocks to find out?, and How many small blocks does it...

Learners determine the power dissipated in the combination of two resistors connected in series to a 6 volt battery. This task assesses students' abilities to develop procedures for an investigation, develop a plan for recording and...

Students investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.

Students measure the mass, volume, length and area of various objects. They are assigned a letter. The task is assesses students' abilities to make simple observations and measurements.

High schoolers circulate through stations to determine the proper instrument to make a certain type of measurement. They must make measurements of mass, volume, length, area, electrical current, temperature and force.

Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's abilities to perform an entire investigation.
