This resource can be used as a class activity or individual practice worksheet. Students are given 12 situations to analyze, and they must decide whether each of them represents a random sample or a biased sample. If being used as a class activity, students should cut out the squares (each situation is on one square). They can then tape them onto the board (have the board divided into 2 categories) based on what kind of sample they believe it is. As a class, you can then discuss each situati

This resource is used to introduce students to mutually exclusive events. Before receiving a definition of this concept, students must determine whether a variety of situations could happen at the same time. Students are then guided through several examples in order to determine the probability of mutually exclusive events (A or B). Two versions of the resource can be used at this point in the activity. In the advanced form (Version A), students work through a card example to find the probab

These guided notes can be used to introduce students to random samples. Formulas and examples are provided to introduce the calculations for sample proportions and margins of error. The second part of the resource contains a page of practice problems that can be given as an individual assignment to assess student mastery. A key is provided.

This practice worksheet is used to introduce the fundamental counting principle. Students will be given 2 situations. In the first situation, they choose the color and size of a shirt. In the second situation, they choose a meal at a restaurant. To demonstrate why the fundamental counting principle works, they create a tree diagram to illustrate the number of possible outcomes. A key is included.

This resource can be used to introduce relative frequency tables (probability distributions). It begins with definitions and a formula for relative frequency (probability). It then provides 2 examples where students create relative frequency tables (probability distributions) based on sets of data. Students also create a bar chart to represent the data in the second example. A key is provided.

These guided notes can be used as the first lesson in a unit on rational numbers. Students learn how to write fractions as decimals, and they learn how to write decimals as fractions. These notes also include a review of place value. Numerous practice problems are given, including a word problem. A key is included.

At the beginning of this resource, students complete a two-way frequency table involving university students (classified by gender and enrollment status). They proceed through a series of questions that help them calculate conditional probability without using the formula. The formula is given after this introduction and students work through five more examples of conditional probability. Two-way frequency tables and tree diagrams are both used to illustrate conditional probability in this as

These guided notes are used to introduce the following terms: data, population, sample, parameter, statistic, qualitative (categorical) data, quantitative (numerical) data, observational study, experiment, simulation, survey. Examples are provided throughout the notes to provide practice with identifying populations/samples, distinguishing parameters/statistics, labeling data as quantitative/qualitative, and determining the method of data collection (observational study, experiment, simulation,

This resource can be used to introduce two-way frequency tables. The difference between marginal and joint frequency is emphasized. Additionally, students learn how to find probabilities by creating two-way tables that show relative frequencies. This resource includes 2 practice exercises. For each of them, students fill in the missing numbers in a two-way table and answer questions about probability by creating a two-way relative frequency table. A key is provided.

This resource includes the following individual worksheets: Notes (2 pages - broken up into 2 parts for 2 consecutive days)Bell Work (2 assignments for 2 consecutive days)Assignment - Supplementary and Complementary Angles (2 pages)Extra Practice #1 - Identifying Pairs of Angles (2 pages)Extra Practice #2 - Complementary and Supplementary Angles (2 pages)Practice - Pairs of Angles (2 pages)A key is included for each resource. The following objectives are addressed in this lesson: Identify adjac

This resource should be used after students have already learned about conditional probability. It can be used to explain how conditional probability is used to test for independence. An overview of this concept is included to help students as they work through two real-world examples. For each situation, students complete a two-way frequency table and calculate a variety of conditional probabilities to determine independence. An answer key is provided.

This resource includes the following individual worksheets: Notes (1 page)Bell Work (1 assignment)Assignment (1 page)A key is included for each resource. The following objectives are addressed in this lesson: Use length and midpoint of a segment.Construct midpoints and congruent segments.

In this resource, students are provided with an overview of frequency tables and histograms. They are then given sets of data to practice creating frequency tables and histograms. Several interpretation questions are also provided. A key is included.

This resource includes guided notes on permutations and combinations including a review of factorial notation. Examples are provided for each concept. In addition to the notes, a two-page practice worksheet is included to check student understanding. A key is provided for all questions in the notes and practice.

This resource includes the following individual worksheets: Notes (2 pages - broken up into 2 parts for 2 consecutive days)Bell Work (2 assignments for 2 consecutive days)Assignment Part 1 - Measuring and Constructing Angles (2 pages)Assignment Part 2 - Angle Addition Postulate (2 pages)Practice - Measuring and Constructing Angles (1 page)A key is included for each resource. The following objectives are addressed in this lesson: Name and classify angles.Measure and construct angles and angle bi

These guided notes include definitions, rules, and examples to help students learn about matrix properties and operations. After each topic is introduced, students are given practice problems to assess their knowledge. The following topics are covered: matrix multiplication, geometric transformations with matrices, determinants of 2x2 and 3x3 matrices, inverses of 2x2 and 3x3 matrices, inverse matrices and systems, augmented matrices and systems. An answer key is included for all student prac
