Probability in Sports

Probability

Grade Level

8th Grade

In this lesson, students explore the concepts of statistics and probability in the context of basketball. Students play basketball in the classroom, gather data about shots made and missed, and calculate the probability of a successful shot. Students then step into the role of an NBA statistician and...

Pythagor-eatin' Theorem

Constructing the Pythagorean Theorem

Grade Level

7th - 8th

This lesson engages students in constructing the Pythagorean theorem using Cheez-It® crackers. Students will not only be able to visually see the theorem, but they will also subsequently prove why the Pythagorean theorem works for all right triangles. Read more »

Slope Matters

Slope-Intercept Form

Grade Level

7th - 9th

In this lesson, students use the Desmos Studio graphing calculator to explore how changing the y-intercept or slope of a line affects the graph. They will find real items to serve as examples of lines with defined slopes and use Desmos Studio to find the linear functions that represent those items.... Read more »

ACT College and Career Readiness Standards - Mathematics (6-12)

N 403: Comprehend the concept of length on the number line, and find the distance between two points

N 503: Work with numerical factors

AF403: Relate a graph to a situation described in terms of a starting value and an additional amount per unit (e.g., unit cost, weekly growth)

AF502: Build functions and write expressions, equations, or inequalities with a single variable for common pre-algebra settings (e.g., rate and distance problems and problems that can be solved by using proportions)

AF503: Match linear equations with their graphs in the coordinate plane

A406: Exhibit knowledge of slope

A514: Determine the slope of a line from an equation

Oklahoma Academic Standards Mathematics (8th Grade)

PA.A.2.1: Represent linear functions with tables, verbal descriptions, symbols, and graphs; translate from one representation to another.

PA.A.2.2: Identify, describe, and analyze linear relationships between two variables.

PA.A.2.3: Identify graphical properties of linear functions, including slope and intercepts. Know that the slope equals the rate of change, and that the y-intercept is zero when the function represents a proportional relationship.

PA.A.2.4: Predict the effect on the graph of a linear function when the slope or y-intercept changes. Use appropriate tools to examine these effects.

Oklahoma Academic Standards for Mathematics (Grade 8)

PA.GM.1.1: Informally justify the Pythagorean Theorem using measurements, diagrams, or dynamic software and use the Pythagorean Theorem to solve problems in two and three dimensions involving right triangles.

PA.D.1.1: Describe the impact that inserting or deleting a data point has on the mean and the median of a data set. Know how to create data displays using a spreadsheet and use a calculator to examine this impact.

PA.D.1.2: Explain how outliers affect measures of central tendency.

PA.D.1.3: Collect, display and interpret data using scatterplots. Use the shape of the scatterplot to informally estimate a line of best fit, make statements about average rate of change, and make predictions about values not in the original data set. Use appropriate titles, labels and units.

PA.D.2.1: Calculate experimental probabilities and represent them as percents, fractions and decimals between 0 and 1 inclusive. Use experimental probabilities to make predictions when actual probabilities are unknown.
