Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

The language and features of functions get careful treatment in a complex but doable lesson. Learners get a lot of practice really figuring out what a graph means in context, and also identifying key features of graphs. Key ideas...

Without ever using the actual term, this exercise has the learner develop the key properties of the midsegment of a triangle. This task leads the class to discover a proof of similar triangles using the properties of parallel...

Statistics is made approachable, and dare we say fun, in this activity on using box-and-whisker plots to analyze and compare data sets. Specific emphasis is placed on interpretations and explanations while graphing, and in using the...

O' Lucky charms! its time for a leprechaun riddle to challenge your learners. So kick those heels in the air and river dance your way to solving this stimulating St. Patrick's Day math question.

Here is a turnkey lesson that walks young statisticians through the development and uses of conditional probability. From dice games to surveys, Venn diagrams to frequency tables, the class learns how a given can effect the overall...

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Your AP Calculus learners probably have their ID numbers memorized, but have they tried graphing them? Pique your pupils' interest by asking each to create a unique polynomial function based on their ID numbers, and then analyze the...

After learning how to convert decimals to fractions and fractions to percents, young mathematicians fill in a chart in which they convert values. Learners convert 0.50 to fraction and percent, 2/8 to a decimal and percent, and 80%...

Young mathematicians analyze computation errors by three hypothetical learners. It begins with a scenario that presents an equation that includes addition, multiplication, division, and subtraction. According to the order of operations,...

A set of worksheets prompts learners to practice solving fraction-based word problems. Each problem involves the division of whole numbers by unit fractions. As they work, mathematicians begin to see how division relates...

Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

Throw some logic into quadratics and see if learners can match a vague graph to multiple equations. Young mathematicians must look at quadrant location, vertices, and intercepts to best match the graph to one or more equations. 

Take a matching problem and take challenging exponential graphs and combine to make one thought-provoking question. Learners look at four higher level exponential functions to match to the four graphs placed together. The equations and...

Let's keep trigonometry simple. When given a cosine ratio, learners must use the clues about the quadrant to determine the sine and tangent ratios. The answer key has a complete worked-out solution to help guide pupils through the...

Encourage middle schoolers to be proficient and knowledgeable in the economic world with a series of personal finance lessons. Focusing on banking, credit, budgets, and investing, the activities guide learners through financial...

Learners find the midpoint between two numbers, shade fractional amounts of rectangles as well as decimal amounts of rectangles, and explain their mathematical reasoning in words. The assessment is a great way to check for understanding...

Direct variation can be applied to many problems and here is a worksheet that has learners practicing them all. The skills include graphing, finding proportional relationships, and solving word problems to show how different factors...

Practice converting with a decimals, fractions, and percents math activity. Learners work to complete 10 problems, each one with a different starting point to the conversion process.    

Add, subtract, multiply, and divide fractions with a worksheet designed to give your learners practice performing fraction operations. 

Obesity is a worldwide concern. Using survey results, learners compare local BMI statistics to celebrity BMI statistics. Scholars create box plots of the data, make observations about the shape and spread of the data, and examine the...

Two lessons for the price of one! Learners use algebra tiles to multiply binomials in the first lesson plan, Next, they use their knowledge from the first lesson plan to factor trinomials into two binomials.

If a linear function and a quadratic function enter a boxing match, which one would win? Learners first review how to find key features of linear and quadratic functions. Next, they compare key features of pairs of functions.

Raise expectations in your classroom and assess learners through the provided performance tasks. Class members must apply concepts learned throughout the year, providing a good measurement of how well they understand the...
