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.

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.

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.

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.

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.

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 bundle includes seven sections of guided notes that can be used during a unit on rational numbers. The following topics are addressed: Terminating and Repeating DecimalsCompare and Order Rational NumbersAdd and Subtract Like FractionsAdd and Subtract Unlike FractionsAdd and Subtract Mixed NumbersMultiply FractionsDivide FractionsAnswer keys are included for all questions.

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 resource begins with notes on experimental design. The following vocabulary is introduced: sample size, control group, experimental group, placebo, placebo effect, blinding, double-blind experiment, randomization, and replication. Practice questions are included to ensure that students can identify elements of a well-designed experiment and find potential flaws in a design. In the second part of this resource, students are asked to design their own experiment to test the validity of a co

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.

This resource can be used to practice finding common denominators. An example demonstrates how to find the least common multiple, and students are given 6 practice problems. A second example demonstrates how to find the least common denominator (LCD), and students are given 6 more practice problems. A key is included.
