How do you find slope? You use points on a line of course. slope. Teach your class how to calculate and differentiate between horizontal and vertical lines. They are sure to be pros at graphing lines on a coordinate plane by the end of...

Learners identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

If you dropped a needle on a lined sheet of paper what is the probability that the needle will cross one of the lines on the page?  Surprise your class with how calculating this probability can approximate pi. This question is known...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Math pupils, by viewing a video, discover the history of pi and some of the applications of its uses in the world today. They conduct an experiment by measuring the diameter and circumference of various circular objects to calculate...

Seventh graders explore estimation, measurement, and probability. Students conduct surveys and create charts & graphs. They study the history of chocolate. Students design their own magazine advertisement or create a script for a...

While just a simple lesson, this activity on experimental probability could provide a way to connect this concept to real life. Learners begin by participating in a probability activity using a coin, and then move on to create their own...

Here is an activity that is intended to highlight a very important issue about precision in reporting and understanding statements in a realistic scientific context. Discuss different ways of reporting the half life of Carbon 14...

Students work together to design a tower from a computer program. They manufacture the pieces with a laser cutter and compete in a competition to determine the best design for stress relief on towers. They discover the work engineers...

Students examine how to calculate the part-per-million and part-per-billion units used to measure contaminant concentrations in the environment. They calculate ratios, take a quiz, analyze a sample chemical spill, and determine if...

Students work together designing and building their own beams. They discover the concepts of stress and strain. They participate in a competition to determine the best beam.

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

Eighth graders explore congruent and similar figures.  In this eighth grade geometry lesson, 8th graders use geoboards to create congruent and similar figures and explore the relationships between the sides and angles. 

Students study the solar system by researching the planets.  In this exploratory lesson students divide into teams and create mobiles.

Learn to calculate the nth term of a sequence defined by an algebraic expression. They examine geometric sequences and series, relate geometric sequences to their explicit forms, find the partial sums of a sequence in a table, and...

Students design and create robotic cars using Legos and the Robolab program. They hold a "snail race" where the slowest car that can be determined to be actually moving is the winner.

Ninth graders will identify/understand the differences between soil and dirt. They will classify soil color accurately and use Munsell notation to describe it (Munsell books provided).Students will classify soil texture using the feel...

Students plot on a coordinate plane. In this algebra lesson, students identify points on a coordinate plane and graph lines given coordinate pairs. They create a model as they study bald eagles and their growth and decay.

Students calculate ppm and ppb by using unit analysis when given a ratio of amounts. They determine in ppm what constitutes a health risk for a particular toxin given data and whether local health officials should close a lake...

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students calculate gas prices. In this transportation lesson, students tally the mileage and gas costs of their car for one months. They figure out how much was spent on gas and create a graph showing average gas prices over time. 

Students explore the mathematical properties of traditional American Indian lodges. They examine the effect of increasing sides of a polygon, calculate the surface area of prisms and cylinders, and construct a classroom size pyramid...

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.
