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.
Students 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.
Students identify the slope of an equation using various methods. In this algebra instructional activity, 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.
In 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.
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.
In 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.
Students explore the concept of trigonometric ratios. In this trigonometric ratios lesson, students use trigonometric ratios and the angle of elevation/depression to determine the height of an object. Students use their clinometer made from a protractor, string, hex nut, and tape to determine the angle of depression/elevation of an object or building. Students determine the height of the object or building using trigonometric ratios.
Tenth graders investigate the properties of absolute value functions. In this Algebra II lesson, 10th graders explore the relationship between the angle created by the branches of an absolute value function and the slope of each branch of the function. Cabri Jr. required.
