Pirate Attack
Arr ye matey, it's time for some trig. Learners first read up on the 2010 attack on the USS Nicholas by a group of pirates and the testimony of one of the witnesses. They use right triangle trigonometry to determine if the account is...
Under the Dome
Card House
Mathematics is stronger than a card house. Pupils watch a video of the beginning of the building of a triangular card house. Scholars come up with questions they wonder about from the video and ask for more information to arrive at an...

Finding the Shortest Distance Between The Spider and The Fly
In this word problem worksheet, students solve for the shortest distance between a spider and a fly. The solution is provided.
Alabama Learning Exchange
"I Saw the Sine"
Discover trigonometric ratios that complement each other. Using two videos, the lesson introduces the trigonometric ratios. The class discovers the relationship between the sine and cosine of complementary angles.
Willow Tree
Perimeter of Common Geometric Figures
Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...
Curated OER
Diagonal Lengths
Students collect, organize, and analyze data while studying the Pythagorean Theorem, measure length and width of several rectangular objects, and compare the measured results to the calculated results.
Curated OER
Mathematical Proofs
Students explore the nature of mathematical proofs and mathematical inquiry. They complete the activity "Using the Pythagorean Theorem". They read selected articles and participate in class discussions.
Curated OER
Tangram Perimeters
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.
Curated OER
Exploring Altitudes in Math
Students draw and calculate altitudes. They draw the altitude of acute, right and obtuse triangles and calculate the altitude of a triangle using the Pythagorean theorem.
Curated OER
2 x 2
Middle schoolers work together to grid a 2 x 2 meter unit using the formula for the Pythagorean Theorem. After creating the grid, they identify the location of artifacts and create a map of their location. They develop a graph and table...
Curated OER
Play Ball
Students calculate baseball statistics and ball field dimensions. In this Pythagorean Theorem, percentages and metric conversion lesson, students are given formulas to find earned run and batting averages for White Sox baseball players....
Curated OER
Investigating Pythagorean Triples
Pupils investigate and solve Pythagorean triples. In this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.
Curated OER
Investigating Triangles 1
Students independently investigate the Pythagorean Theorem. They are given a set of triangles that involve whole number Pythagorean Triples. The main focus of the lesson is exploration rather than discovering the Pythagorean Theorem.
Curated OER
Circles
Students review the definition of a circle and the general formula for a circle to specific problems. They also write the equation for a circle given the center and radius of the circle. Students then define a circle using either the...
Curated OER
Homer/Scarecrow Worksheet
In this Pre-calculus worksheet, students consider a scenes from The Wizard of Oz and The Simpsons refering to the Pythagorean Theorem. Students analyze the statement for errors and write about another mathematical formula...
Curated OER
Worksheet 17-Fall 1995
In this math worksheet, students find y' both implicitly and explicitly for given relations. They find y' using implicit differentiation for a given relation. Students prove the Pythagorean Theorem
Curated OER
Is It Right Angled Triangle?
In this right angle triangle worksheet, students check whether the four given triangles are right angled triangles using the Pythagorean Theorem.
Curated OER
Right Triangle Geometry
Students study the basic principles of right triangle geometry needed to solve for unknown values of a right triangle. They apply and master the principles of right triangle geometry by solving problems.
Curated OER
Designing a Fort
Students explore the concept of right triangles. For this right triangle lesson, students construct a scale model of a tourist attraction similar to Fort Jefferson. Students research aerial photos of Fort Jefferson, then build their...
