This activity presents a real-world problem about an epidemic of influenza spreading through a city. Learners refer to a graph that shows the number of individuals infected in relation to the number of weeks that have elapsed since...

Once you start looking, angles appear everywhere in our daily lives. A creative lesson has learners use the angles created by a fuel gauge to practice the Angle Addition Postulate. They see how changing the angle parts does not...

Why are right triangles so special? Pupils begin their study of right triangles by examining similar right triangles. Verifying through proofs, scholars recognize the three similar right triangles formed by drawing the altitude. Once...

Exponential functions and their growth rates are explored concretely using tables in a collaborative task. Then the successive quotient is explored algebraically.

A short, multiple choice assessment that determines your 3rd graders' ability to correctly compare fractions with like denominators. This quiz asks learners to compare two fractions using words, the greater than/less than symbols, and...

In this college level Pre-Calculus worksheet, students determine if a given relation is a function, graph functions and observe their behavior, and determine if a function is even, odd, both, or neither.  The four page...

In this grade 5 number sense worksheet, students complete a total of 25 problems covering a wide range of 5th grade math number sense concepts. Answers are included.

In this relations and functions learning exercise, students answer 5 multiple choice questions that involve finding domain and range and function notation.

Students define Pascal's triangle and special notations used to represent nth elements. In this geometry lesson plan, students solve problems using permutations and combinations. They compare the formula for permutation to that of...

Fractions can be tricky. Why not have kids think of fractions like they think of eighth, quarter, and half notes? In teams, the class creates four-measure patterns with their percussion instruments. They need to explain their rhythm...

Build on the understanding of finding angles using trigonometric ratios. Pupils develop the definitions of inverse trigonometric functions by restricting their domains in the 13th lesson of a 16-part series. They use inverse functional...

Ready to study inequalities with your class? Use this activity to solve multi-step inequalities and graph the solutions. The document would be great to use as a study guide as you present the material, or could easily be modified and...

When do teams want a strike? When they are playing this fun math game modeled after bowling. First, class teams roll four dice to generate the numbers they will use in that round, called a frame, of the game. Next, pins numbered 1...

Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

In this evaluating expressions learning exercise, learners solve and complete 50 various types of review problems. First, they complete each sentence and define the listed terms. Then, students evaluate each expression for the given...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...

This traditional textbook style unit includes vocabulary, a direct explanation section, examples, practice problems that directly line up with the explanations and examples, and a unit summary review and practice problems. Learners get...

Paper or plastic? Explore the environmental effects of using plastic bags through mathematics. Learners manipulate worldwide data on plastic bag consumption to draw conclusions.

Sometimes the best things are already done for you! Here is a six-problem quiz that has a variety of problems ranging from solving quadratic equations to interpreting a function. The piece-de-resistance is the worked out answer key in...

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

In this fractions/interval notation worksheet, students write expressions as single fractions, complete problems with nonzero real numbers with unknown values and write sets in interval notation.

Learners explore the extreme between the distance to the moon in comparison to the size of a particle of moon dust and solve problems related to the Apollo space missions.
