Coordinate Geometry
Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...
Curated OER
Transformations Using the Geometer's Sketchpad
Young scholars discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.
Curated OER
Using Trigonometry
Fifth graders explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practicing the new skills. Students...

Triangle Explorer
Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.
Curated OER
The Distance to an Unapproachable Point
Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.
Curated OER
How far is a km?
Learners explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.
Curated OER
Displacement Problem Set
Students calculate the length of a side of a triangle using a trigonometric function. They calculate the measure of an angle given two sides of a triangle with a trigonometric function.

Speed Is the Key
Students design and build a model downhill ski course that proves to be the fastest course at the Finish Line. They apply what they explore angles, slope, speed, and surface conditions to find the fastest course in the US.
Curated OER
Paper Pool
Students analyze the measurements of rectangles. In this analysis lesson, students will investigate patterns by looking at ratios. Students will also hypothesize the probability of a ball going into a certain pocket when playing pool....
Curated OER
Signal Flags
Students examine the use of signal flags on vessels. They use measurements and symmetry to create their very own signal flag. Students work together and as individuals to solve problems and express their ideas.
Curated OER
Trigonometry
Eighth graders practice calculating the unknown length of a right angle triangle. They also examine the pythogoram theory in groups. They help each other work through the problems.

Altitude Tracking
Students construct simple altitude tracking devices for determining the altitude a rocket reaches in its flight. They estimate the altitude a rocket achieves during flight.
Curated OER
Transformations and Rotations
Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
Curated OER
Probability and Geometry
Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...
Curated OER
The Tangent Ratio
Students calculate the tangent ratio given a right triangle. For this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
Trigometric Ratios
This instructional activity requires a worksheet that is not connected. It is integral to the instructional activity.
Curated OER
Similarity and Congruence
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.
