Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...

Gain a deeper understanding of the base 10 system through practicing conversion to Roman numerals through one million. The class is taught how to read the numerals through modeling and guided practice. This lesson includes a homework...

Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the size...

Students investigate Mayan Numbers. In this algebra lesson, students compare our number system to the number system of the Mayans. They identify base 10 and base 20 numbers including zero in the Mayan symbols. They solve a Mayan problem.

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Investigate expected value as a long-run average. The eighth installment of a 21-part module has scholars rolling pairs of dice to determine the average sum. They find aggregate data by working in groups and interpret expected value as...

Students explore the concept of probability.  In this probability lesson, students use area to determine probability.  Students use charts and spinners to help determine the probability of events such as flipping a coin or...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

Third graders determine that the larger the denominator the more parts the whole is being divided into. They use fractions to communicate and compare parts of the whole. They discover what the numerator and denominator of a fraction...

High schoolers investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate....

Learners describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.

Students solve linear inequalities. In this solving linear inequalities lesson, students solve one step inequalities algebraically. Students graph the solutions on a number line. Students compare the graphs of various inequalities such...

Students add integers using a number line. In this algebra instructional activity, students add one and two digit integers. They compare zero pairs and the addition of integers.

Middle and high schoolers complete and solve 12 various types of problems. First, they express the output as a function of the input in each table. Then, pupils evaluate for the given variable when the value is as stated. In addition,...
