Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.https://education.ti.com/en/activity/detail/the-normal-distribution_1
Is it Normal
In this activity, students will use the idea of a normal distribution to pull together multiple areas of probability and statistics.https://education.ti.com/en/activity/detail/is-it-normal
Graphical Displays of Univariate Data
Students will sort data and construct stemplots, dotplots, histrograms, and frequency plots.https://education.ti.com/en/activity/detail/graphical-displays-of-univariate-data
Sampling Distributions
Students studies the distribution of sample proportions with a simulation. They find small sample size leads to skewed distribution and as the sample size increases, the distribution becomes more normal.https://education.ti.com/en/activity/detail/sampling-distributions
Box Plots
In this lesson, students plot the two extreme values (minimum and maximum), the lower quartile (LQ), upper quartile (UQ), and the median (a five-number summary) on a number line to create a graph called is a box plot.https://education.ti.com/en/activity/detail/box-plots-bc
Banquet Meal
Students use proportional reasoning skills to increase a family-size recipe to a banquet-size recipe.https://education.ti.com/en/activity/detail/banquet-meal
Golden Rectangles
Students measure rectangles and calculate ratio between the sides. They compare the ratio to the Golden Ratio (1.618).https://education.ti.com/en/activity/detail/golden-rectangles
Thrift Store Markdowns
Students will calculate a series of discounts using increasing unit fractions.https://education.ti.com/en/activity/detail/thrift-store-markdowns
Match the graph
Students use the Cabri Geometry II Plus software to reflect points from a graph across the axes.https://education.ti.com/en/activity/detail/match-the-graph
Conics in Geometry
This lesson has students construct 3 conic sections through geometric definitions. Using the CABRI™ Geometry II application for the TI-89, students construct a parabola, an ellipse, and a hyperbola. (Topics - geometric shapes.https://education.ti.com/en/activity/detail/conics-in-geometry
Finding the area of a perfect polygon.
To find the area of a "regular polygon."https://education.ti.com/en/activity/detail/finding-the-area-of-a-perfect-polygon
Making Cookies
Students will reduce a cafeteria recipe to suit a household recipe. They use compatible numbers to choose smaller measurements while retaining the original proportions.https://education.ti.com/en/activity/detail/making-cookies
Building Expressions
In this lesson students view expressions as objects in their own right and interpret the form and structure of an algebraic expression. Students focus on comparing expressions and establish a foundation for the definition of equivalent expressions. Students also consider how to verify that expres...https://education.ti.com/en/activity/detail/building-expressions-bc
Modeling Median Incomes
In this activity, students investigate and examine the data underlying the claim that women’s income is catching up to men’s income.https://education.ti.com/en/activity/detail/modeling-median-incomes
What is a Variable?
In this lesson students evaluate expressions, write expressions that correspond to given situations, and use expressions and formulas to solve problems. Students also examine a product of the form ax for given integer values of a in terms of how the value of the product changes for a one unit cha...https://education.ti.com/en/activity/detail/what-is-a-variable-bc
What is an Equation?
In this lesson students begin by establishing the difference between an expression and an equation. Students then investigate expressions and equations to develop what it means to have a solution to an equation.https://education.ti.com/en/activity/detail/what-is-an-equation-bc
What is an Exponent?
Why are exponents useful and how do they behave? An exponent indicates how many times the base to which it refers is a factor; i.e., in , the 4 indicates that the base, 3, is used as a factor four times. This lesson focuses on how the definition can be used in a variety of situations to make sens...https://education.ti.com/en/activity/detail/what-is-an-exponent--bc
Equations and Operations
In this lesson students investigate the relationship between the solution to an equation and the solution to a new equation formed by adding, subtracting, multiplying, or dividing one or both sides of the original equation by a numerical value. Students develop an understanding of “solution...https://education.ti.com/en/activity/detail/equations-and-operations-bc
Ready, Set... Solve!
In this coding activity, students will create a fast-paced game to help practice solving multi-step equations.https://education.ti.com/en/activity/detail/ready-set-solve
