Learners use cartesian coordinates (x,y,z) in 3-dimensional space. [Optional: appreciate there exist two ways of defining the z axis, and which of them is used.] They become familiar with the tools and terms used by surveyors.

Ninth graders explore how Aristarchus used the position of the half-full Moon to estimate the distance to the Sun, and how he made a great error, but still figured out that the Sun is much larger than Earth.

High schoolers read Forces in a Climb from the Beginner's Guide to Propulsion, and explain each of the formulas using vectors.

Students complete a variety of bear-related activities. They sort and graph teddy bears, distinguish between real and non-real bears and research bear life cycles and habitats.

First graders explore estimating and measuring distances. They analyze and discuss a map of New York State, make estimations, measure distances using yarn, and calculate total distances between cities on the map.

Students investigate the Metric System. They discuss the history of the Metric System, convert various units of measurement into the Metric System, and solve problems on a spreadsheet.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Students look at ratio, what it means for numbers or objects to be in a given ratio, and how ratios and fractions are related. They write and solve story problems which involve whole numbers, using addition, subtraction, multiplication,...

Twelfth graders discuss sine curves and enter equations into their graphing calculator then compare different graphs created on their calculators. They identify the period, amplitude and phase shift given the graph or the equation of a...

Students explore circular functions. They identify the amplitude, period, phase shift and vertical shift of circular functions. Students analyze phenomena described by sine waves and they find mathematical models for transforming images...

Students investigate the measurements and geometry of the school grounds. They conduct inquiry while measuring the campus and some of the city blocks. Then students draw a map to scale and categorize property types using a pie graph.

Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.

Students review the days of the week and tell what the current day is by singing a song. They fill in the sentence telling the day of the week it is and then discuss what day yesterday was and the name of the day tomorrow and then talk...

Students discussion frictional force, kinetic friction, and static friction and the role each plays in acceleration and velocity in relationship to a car and the road on which it is traveling. Students complete lesson answering review...

In this error correction worksheet, students analyze 22 sentences which may contain errors in grammar. Students decide if there are mistakes and correct them.

For this algebra expressions worksheet, students solve 10 various problems that include solving algebraic expressions. First, they substitute each given expression into the appropriate place and then solve the equation. In addition,...

Students explore the concept of chemical formulas.  In this chemical formula lesson plan, students watch a video about balancing chemical equations.  Students conduct an experiment using silver nitrate and sodium...

Students measure the height of items using an astrolabe.  In this latitude lesson students construct a sextant and determine height and latitude with it. 

Students design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.

Students experiment with radio transmitters. In this transmission of waves lesson, students use an FM radio, an attenuate, and the frequency to locate a radio transmitter. Students discuss outcomes. 

Pupils will determine distances to nearby stars using parallax. In this Astronomy lesson plan, students will use a web program, trigonometry, and sketches to determine the distance of stars.

Students find the different ratios of a right triangle. In this geometry lesson, students apply the concept of the Pythagorean theorem as they identify the different angles and parts of a Unit Circle. They find the ratios of sine,...

This multimedia Learn Alberta math resource looks at how trigonometry is used in making sure that airplanes land safely at airports. The accompanying interactive component gives students practice in using trigonometric ratios, namely...

Resource provides trigonometry formulas for unit circle, reciprocal identities, ratio identities, Pythagorean identities, sum and difference formulas, and double-angle formulas.
