New ReviewThere is power in spreadsheet formulas and learners use this power to model quadratic data. Given a scatterplot of a parabola, pupils create formulas in a spreadsheet to populate the data. The formulas they use lead to an understanding...

New ReviewLearners create patterns in a table to mimic the function of an electronic spreadsheet. The result is a table that creates an addition table for decimals in intervals of one-tenth. While creating the pattern, pupils must thoroughly...

New ReviewClass members have some catching up to do. Given a linear equation describing the distance of a runner, young mathematicians interpret the equation in terms of the context. They consider a general equation of the same form and describe...

New ReviewKnow thy calculator. Young mathematicians use their calculators to answer a set of questions. They consider how the number of digits the calculator displays affects the answers to calculations. They then find examples of computations...

New ReviewStrive for gold with an informative resource. A short task challenges learners to investigate the thickness of a box made from a given volume of gold. The box must have specific dimensions, so setting up and solving a literal equation is...

New ReviewKen Burn's epic documentary miniseries The Civil War, broadcast in 1990, was the most-watched PBS program ever. A question sheet helps viewers keep track of events in the first episode of the documentary.

New ReviewFind the function that fits. Scholars first identify the graph of a function that looks the same after a horizontal translation. They must then find the equation of a function whose graph lies only in two adjacent quadrants.

New ReviewWriting and sketching functions—what more could you want to do? Learners write and sketch functions that meet certain conditions as they complete a short task. They find a parabola that encompasses three quadrants of the coordinate plane...

New ReviewOral storytelling has been an important part of every culture. The time-honored practice uses stories as a conduit for a culture's values and customs from one generation to the next. Keep the tradition going with a family interview...

New ReviewHere's a task that is out of this world! Given a description of a fictional cube-shaped planet, scholars answer a set of questions about the planet. They create a two-dimensional map and consider the distances between locations on the map.

New ReviewRound and round and round we go. Given a diagram of three circles, two of which share a point with the third circle, learners identify the radius of each circle. Doing so requires setting up and solving a system of equations based on the...

New ReviewStretch your mind about triangles. Given a triangle, scholars consider a smaller triangle formed when they stretch three rubber bands from each vertex to the opposite side. They determine the ratios of the areas and perimeters of the...

New ReviewDon't run from the resource—sprint to it. Using an engaging performance task, scholars consider a set of constraints on the creation of a track. Given several possible designs, they determine if the designs meet the constraints. If not,...

New ReviewTransform your lesson for transforming functions. Scholars transform linear, quadratic, exponential, rational, and trigonometric expressions. They write their expressions to fit specific forms and identify the values of the resulting...

New ReviewChange the way you teach about rewriting expressions. A diagnostic task asks learners to transform expressions in different ways. Given two linear expressions and two quadratic expressions, they rewrite them into the indicated forms.

New ReviewThree angles in a triangle, three-dimensional space, it all seems connected somehow. Given several different triangles, pupils use the three angles of the triangle as coordinates to plot points in three-dimensional space. They explore...

New ReviewTake a look at a star resource. Young mathematicians use a graphing calculator to draw intersecting lines that look like a star. They then apply translations to move the entire star and also consider what transformations must occur to...

New ReviewSorting memories doesn't have to be difficult. Young mathematicians evaluate two different methods of sorting yearbook pictures. They answer a set of questions to explore each method, then develop their own sorting procedure based on...

New ReviewThere are zero reasons not to learn about zero coupon bonds. Given information about the interest rate and closing price of a zero coupon bond, future investors determine the purchase price of the bond. They then consider the...

New ReviewHow hard can it be to measure out two pounds? A short performance task introduces a situation where a balance scale is broken. It gives a method for measuring out two pounds and asks learners to evaluate the procedure. They must prove...

New ReviewLet the resource quench your thirst for knowledge, like a vending machine that dispenses drinks. Future computer scientists develop an algorithm to identify the fewest number of coins that a vending machine could use in creating change....

New ReviewJump at the chance to use parabolas. Young mathematicians apply trigonometry to explore the trajectory of a ball in different situations. Some walls cause the ball to bounce, so participants must consider all possibilities.

New ReviewSort out who's who from the Battle of the Alamo with a helpful crossword puzzle. Complete with 20 clues and names, the resource helps history learners identify the major players in a pivotal moment in American history.
