Random sampling is as easy as choosing numbers. Teams use random numbers to create a sample of book lengths from a population of 150 books. The groups continue by developing a technique to create samples to compare from two populations...

Scholars apply the concepts of box plots and dot plots to summarize and describe data distributions. They use the data displays to compare sets of data and determine numerical summaries. 

Students investigate the correlation between education and salary. For this business lesson, students analyze the salary rate for different jobs to determine if there is a correlation between the two. They graph their findings and report...

In this integers learning exercise, students solve and complete 8 various types of word problems. First, they read each problem and determine from the information what they are looking for. Then, students determine the operations...

A function is like a machine that has an input and an output. Challenge scholars to look at the eight given points and determine the two functions that would fit four of the points each — one is linear and the other non-linear. The...

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Explore different representations of numbers. Scholars convert between fractions, decimals, and percents, and then use these conversions to plot the values on a horizontal number line.

Working with transformations allows the class to take a turn for the better. The short assessment has class members perform transformations on the coordinate plane. The translations, reflections, and rotations create pattern designs on...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Youngsters show understanding of accurate division of whole number, decimals, fractions, and percents using manipulatives (candies). They use white boards to demonstrate their understanding of representing numbers as defined in the...

Learning how to write computer code has never been so much fun! Given control of their very own robots, children create simple programs in order to solve a series of challenges and develop their problem solving skills.

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

First graders,working on computers, drag coins into boxes to equal amounts pictured. Following a demonstration, they demonstrate how to type number sentences. As an extension, 1st graders create equivalent amounts using specific numbers...

Students examine and discuss a variety of ways to measure length, capacity, and weight. They estimate and measure a pencil's length using Unifix cubes, estimate and fill a measuring cup with Unifix cubes, and weigh a calculator in a...

In this exploring slope worksheet, students solve and complete 4 different problems. First, they compare an object's weight on Earth to an object's weight on another planet using the information given. Then, students compare this...

There are four activities in this extensive lesson covering the identity matrix and scaling, the linear representation of translations, the linear representation of rotations, and reflections. In small groups, they use the Cabri II...

What will be on the test? The resource provides comprehensive review items for the content of the unit on exponents. The resource divides the sections in the order you present the lessons during the unit. 

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

Learners take the abstract concept of binary representation and create a more tactile and concrete approach. Using egg cartons, they create a physical representation of binary numbers. The egg cartons become a tool to assist students in...
