#### On the Road to Zirbet

The road to a greater knowledge of functions lies in the informative resource. Young mathematicians first graph a square root function in a short performance task. They then use given descriptions of towns and the key features of the...

Lesson Planet

#### Not So Identities

Don't compromise the identity. Given pairs of equations, scholars determine whether the equations are true for the same set of values. They explain their reasoning, considering whether it's possible to combine the equations into an...

Lesson Planet

#### Mystery Dice

Dice aren't typically mysterious devices, but these dice are anything but typical. Scholars try to come up with dice that match given information on the relative frequency when they roll them a certain number of times. They must then...

Lesson Planet

#### More or Less

How long can the cable get? A short performance task provides learners with information on the length of cables and the margin of error for each. They must determine the longest and shortest cable possible by splicing these cables.

Lesson Planet

#### Mirror, Mirror I

How do you see yourself? Young mathematicians consider whether it's possible to view their whole bodies in a mirror with a length that is half their height. They write a letter to a friend explaining their positions mathematically.

Lesson Planet

#### Metric Volume

Master metric measurements. Given the fact that the volume of one milliliter of water is one cubic centimeter, scholars figure out the volume of one liter of water. They must determine the correct unit of length for a unit cube that...

Lesson Planet

#### Measuring the Unit Circle

Here's the right task to investigate right triangles in the unit circle. A short performance task has learners determine the product of two side lengths in a unit circle. They must apply similarity concepts and trigonometric ratios to...

Lesson Planet

#### Maximum Volumes

It's great to have a large swimming pool. An interesting performance task asks learners to optimize the volume of pools for a given surface area. They consider four different shapes for pools and find the maximum volume for each pool.

Lesson Planet

#### Maintain Your Composition

Compose yourself! Learners first use given graphs of functions f and g to graph the composition function f(g(x)) and identify its value for a specific input. They then consider functions for which f(g(x)) = g(f(x)).

Lesson Planet

#### Losing Track

Don't lose the chance to use the task. Given three diagrams of curved pieces of wires, young mathematicians must explain whether it's possible to conclusively match the wires as representing cubic, exponential, or quadratic functions....

Lesson Planet

#### Look High and Low

From the highest high to the lowest low here's a resource that won't fall flat. Given data on the area and the highest and lowest elevations of each of the 50 states, learners decide which states are the least flat and the most flat. Of...

Lesson Planet

#### Look but Do Not Touch

We seem to keep missing each other. A short task provides pupils with a quadratic function, as well as a linear function with a missing coefficient. They must determine the value of the coefficient for which the graphs do not intersect.

Lesson Planet

#### Dubious Dice

How many ways can you slice dice distribution? A short performance task asks pupils to consider different types of distributions. Given histograms showing a triangular distribution and a bimodal distribution, they create pairs of dice...

Lesson Planet

#### "Equal" Equations

Different equations, same solution. Scholars first find a system with equations y1 and y2 that have a given solution. They then find a different system with equations y3 and y4 that have the same solution. The ultimate goal is to...

Lesson Planet

#### Values Survey

What are the most important values a person possesses? Teens and parents take a collaborative survey and discuss what values are important to them. They return the signed form to the teacher to confirm they completed the activity.

Lesson Planet

#### Generation of Respect

R.E.S.P.E.C.T. Learners find out what it means to them. Scholars write sentences, do a word sort, and list what makes them grateful. Additionally, pupils learn how to be more respectful by completing worksheets that would make Aretha...

#### King for a Day

Rumor has it exponential functions help solve problems! In a kingdom filled with rumors, young scholars must determine the speed a rumor spreads. The ultimate goal is to decide how many people must know the rumor for it to spread to the...

Lesson Planet

#### Isosceles Triangle Spaces

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Lesson Planet

#### Intersections I

One, two, or zero solutions—quadratic systems have a variety of solution possibilities. Using the parent function and the standard form of the function, learners describe the values of a, b, and c that produce each solution type. They...

Lesson Planet

#### In a Triangle

What's in a triangle? Just 180 degrees worth of angles! Young learners use given angle relationships in a triangle to write an algebraic representation. Using a system of equations, they simplify the equation to a linear representation.
