Curated OER
Tangents to a Circle
Young scholars construct tangent lines. In this geometry instructional activity, students identify the point of tangency, secant and tangent lines. They graph the lines on the Ti and make observations.
Curated OER
Transformations: Dilating Functions
Young scholars dilate functions using transformation. In this algebra lesson plan, students complete vertical dilation, stretch and shrink. They perform reflection across the x and y axis.
Curated OER
Vertex and Factored Form of Quadratic Functions
Students graph quadratic equations. In this algebra lesson, students solve quadratic equations by factoring. They identify the end behavior of the graph.
Curated OER
The Function Elevator
Pupils solve and graph functions. In this precalculus lesson, students use piecewise function to relate real life scenarios. They analyze the graphs and identify the vertex and intercepts.
Curated OER
Particle Motion1
Students analyze piecewise functions. In this precalculus lesson, students identify the position, velocity and distance. They analyze the relationship between the graph, its position and velocity.
Curated OER
Crossing the Asymptote
Learners investigate graphs and their asymptotes. For this precalculus lesson, students examine the numerator and denominator of their rational functions. This helps them identify where and when the graph will cross its asymptote.
Curated OER
The Unit Circle
Students solve problems using the unit circle. For this precalculus lesson, students identify angles using the properties of the unit circle. They observe the trigonometric graphs and sine, cosine and tangent.
Curated OER
Rose Curve
Arcsine will be better understood and applied through prediction the number of petals on a rose curve using polar equations. Students relate rose curve to siusoidal functions using the Ti navigator.
Curated OER
How to Make Histograms
Young scholars collect data and plot it using a histogram. In this statistics activity, students interpret histograms. They find the frequency, percents and density.
Curated OER
Analyzing Country Data
Students analyze different data in percentage form. In this statistics lesson, students plot data using box-plots, dotplot, and histogram. They compare and contrast the collected data using the boxplot.
Curated OER
Boxplots Introduction
Young scholars describe the pattern of a bell curve graph. In this statistics lesson, students move data around and make observation about the mean, and the quartiles. They define boxplot, outlier, range and other important vocabulary...
Curated OER
Center and Spread
Pupils collect and analyze data. In this statistics lesson, students define and calculate the range, median and standard deviation. They identify reasons for a skewed distribution.
Curated OER
Why NP Min?
Students calculate the normal distribution. In this statistics lesson, students use the normal distribution to estimate binomial distributions. They define when to use NP and n(1-p) to make approximations.
