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

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.

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 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 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.

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

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.

This resource can be used to introduce or reteach the following topics: Adding integers with the same or different signsSubtracting integers with the same or different signsMultiplying/Dividing integers with the same or different signsRules are included in each section to remind students when the final answer is positive or negative. Each example also walks students through the correct thinking process. (For example, the sum is ________ because both integers are _________.) A key is provided.

This worksheet can be used for extra practice and review when comparing rational numbers. A chart of common conversions is included that lists fraction, decimal, and percent equivalencies. Students use long division to write fractions as decimals, write fractions as decimals without using long division, write decimals as fractions, compare fractions using inequality symbols, and order rational numbers from least to greatest. Several word problems are included. A key is provided.

This bundled resource includes a unit test and 2 review worksheets that can be used as practice. One of the review worksheets includes questions that directly align with a similar question on the unit test. A key is provided for each resource.

This resource can be used to introduce students to the following concepts: standard deviation, range, interquartile range, z-score, empirical rule. Students first calculate the standard deviation of a large data by following step-by-step instructions before getting a formula. Example problems, formulas, and definitions are then included to illustrate the other concepts. A key is provided.

This review can be used as practice before a unit test (also available for sale). The following topics are covered: 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.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

These guided notes can be used while teaching a unit on integers. The first lesson introduces integers and absolute value. The second lesson covers the addition of integers. The third lesson covers the subtraction of integers. Finally, the fourth lesson covers the multiplication and division of integers. Word problems are included in each lesson, and many practice problems are provided. A key is also given for all questions.

This resource can be used as an assignment during a lesson on subtracting integers. Students subtract positive and negative integers in the first 12 questions. Students also evaluate subtraction expressions by plugging in given values for variables. Several real-world applications are included. A key is provided.
