Operation Mathematics

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

In this project, students are given three scenarios to choose from. They can own a new restaurant, clothing store, or sporting goods store. For each situation, they are given a list of categories that can be used to create customer choices. They will then relate their menu (or catalog) to probability and, more specifically, the fundamental counting principle. A rubric is provided to guide instructor grading. This is an open-ended project, so it is accessible to both beginning learners and a

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.

In this assignment, students are asked to find probabilities based on a variety of real-world situations. Both experimental and theoretical probability are included. Additionally, students must make a prediction based on experimental probability in one question. An answer 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.

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.

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 assignment can be used to assess the following concepts: distinguishing statistics and parameters, identifying populations and samples, and differentiating between quantitative/qualitative data. Numerous situations are also given to test whether students can determine if a study is an experiment, survey, or observational study. A variety of question types are included (true/false, short answer, fill in the blank). A key is provided.

This test can be used to assess the following topics: Use long division to write fractions as decimals.Write fractions as decimals without using long division.Write decimals as fractions.Use inequality symbols to compare fractions.Order rational numbers from least to greatest.Add or subtract fractions and mixed numbers (involving positives and negatives).Multiply or divide fractions and mixed numbers (involving positives and negatives).Several word problems are given. A key is included.

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.

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 can be used as a quiz during a unit on integers. The following topics are covered: Ordering integers from least to greatestUsing integers to represent real-world situationsAdding and subtracting integers (with the same and different signs)Graphing integers on a number lineEvaluating expressions involving absolute valueNote that multiplication and division are not covered on this quiz. Several word problems are included. A key is provided.

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 class activity contains 2 experiments. The first part involves standard dice, and the second part involves coins. The activity also serves as guided notes because definitions and formulas are embedded for the following terms: probability, outcome, sample space, experimental probability, and theoretical probability. In the first experiment, students roll a standard die 50 times to find the experimental probability of each outcome. They then answer questions to compare their results with

In this activity, students will play Let's Make a Deal with a partner. They will play 50 times with switching doors and 50 times without switching doors. Then, they will calculate the winning percentage based on each decision to decide whether it is a good idea to switch doors. At the end of the activity, students will be challenged to extend the game to 4 doors instead of the usual 3. This activity is designed for groups of 2-3 students. One option is to use 3 cups with a small prize under

These notes can be used as the fifth lesson in a unit on rational numbers. Students practice adding and subtracting mixed numbers with and without common denominators. Note that this lesson should be given after students have learned how to add and subtract fractions. Numerous practice problems are provided, including a real-world application. A key is included.

These notes can be used as the fourth lesson in a unit on rational numbers. Students practice adding and subtracting fractions without common denominators. Note that this lesson should be given after students have learned how to add and subtract like fractions. Numerous practice problems are provided, including a real-world application. A key is included.

These notes can be used as the third lesson in a unit on rational numbers. Students practice adding and subtracting fractions with a common denominator. Note that this lesson should be given after students have learned how to add and subtract integers. Numerous practice problems are provided, including a real-world application. A key is included.

This assignment includes a variety of questions that assess student understanding of permutations, combinations, and factorial expressions. Real-world application questions and basic formula questions are included. A key is also included with answers to all questions.
