Intersecting Lines and Segments of Measures
Mathematicians measure intersecting lines-and circles, and create chords. In this geometry lesson plan, students explore interrior and exterior chords created by tangent and secant lines. These segments can be inside the circleor outside the circle.
Young scholars derive the six trigonometric ratios. In this trigonometry lesson, students use trigonometric properties to find the missing angles of triangles.
NY State Education Department
Young scholars review the standards expected of them in their different math classes. In this math review of different indicators, students review a chart that holds them accountable for certain standards. They answer questions about each indicator and what supplies are needed to help each indicator be completed.
Swet and sour with a hat
Eleventh graders explore the TI-InterAcitve!. In this Algebra II lesson, 11th graders examine features of the TI-InterActive! including drawing on a Graph, using Stat Plots, exploring the syntax for piecewise functions, and using sliders in order to obtain parametric variations. The lesson is designed to encourage students’ creativity.
Looking at Polynomials as Dynamic Mathematical Objects
Learners explore graphs of polynomials. In this Pre-calculus/Calculus lesson, students investigate the problem of constructing the expression for a polynomial curve based on the dynamic properties of the curve. TI-Interactive is required to perform the algebraic manipulations.
In this geometry worksheet, students plot coordinate pairs and connect the points to create different shapes. They give th shapes its polygon's name. They differentiate between simple functions and rectangular hyperbola.
Slopes and Slope Intercepts
Students identify the slope of an equation using various methods. In this algebra lesson, students graph linear equations and calculate the slopes using the x and y intercept to solve the equations and graph the lines. They use the slope intercept formula to find the slope.
NUMB3RS Activity: Implicit Orbits
In this algebra worksheet, students solve word problems using algebraic equations and implicit differentiation. There are 16 problems dealing implicit differentiation.
Students use a problem in a real-world context to motivate the need to construct circumcenters and then incenters of triangles and to make sense of these constructions in terms of bisecting sides and angles.
Tenth graders explore inscribed angles. In this geometry lesson, 10th graders investigate the relationship between an inscribed angle and its intercepted arc. The dynamic nature of the geometry utility allows for conjecture and verification.
For this quadrilaterals worksheet, 10th graders solve and complete 20 various types of problems. First, they find the length of a corresponding side of a pentagon. Then, students find the measure of an exterior angle of a regular seven-sided polygon. They also find the length of the radius of a cylinder.
Worksheet 28: Parametric Equations
For this parametric equations worksheet, students read informational paragraphs and answer 10 questions regarding parameter, velocity, speed, curvature, parametric equations, and scalar curvature.
Applying Trigonometric Functions To Real Life
Students examine where trigonometry exists outside the classroom. In this trigonometry lesson, students create trigonometric functions to match the data provided and to solve word problems relating to the real world.
Technology for Displaying Trigonometric Graph Behavior: Sine and Cosine
Young scholars explore the concept of sine and cosine. For this sine and cosine lesson, students work in groups to graph sine and cosine functions. Young scholars examine how coefficients in various parts of each parent function shift the graph. Students discuss vertical and horizontal shifts as well as shrinks and stretches of the parent graphs.
Exploring the Circular Motion of a Tennis Ball
Students are introduced to the concept of circular motion. In groups, they participate in experiments to discover the law of inertia. They describe how forces act on objects during a circular motion. To end the lesson, they use these two concepts to predict the path of an object.
For this geometry review worksheet, 10th graders solve and complete 33 different problems that include identifying various geometric figures and parts of a circle. First, they find the radius of each circle given its diameter. Then, students use the diagram to match the notation with the term that best describes it. They also determine the measure of each angle or arc shown.
