Explore linear programming on a website game. Partners solve a real-world problem by setting up an objective function and a linear inequality. They graph their results on chart paper and also using a calculator before presenting their...

Explore politics by analyzing the voting process. Pupils discuss the purpose of casting votes in an election, then examine graphs based on the data from a previously held election's turnout. The lesson concludes as they answer study...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

Exactly how fair are the board games children grow up playing? Young mathematicians investigate this questions as they work their way through this five-lesson series on basic probability. 

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

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,...

When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a worksheet that engages scholars to properly label line graphs. It then requests two applied reasoning answers.

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Enough stuffed crust to go around. Pupils calculate the area and perimeter of a variety of pizza shapes, including rectangular and circular. Individuals design rectangular pizzas with a given area to maximize the amount of crust and do...

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...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Review basic probability concepts with your class using different-colored marbles in a bag. Then pair up learners and have them play a cool online interactive game in which they race miniature cars using the roll of a die or...

Elementary or middle schoolers use ratios to discover some nearly constant relationships between measurements of parts of the human body. They find and record pairs of measurements and determine the relationship between the pairs. Pupils...

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...

Learners use the Frayer model during problem solving. In this problem solving lesson, they examine multiple methods of data collection to solve real world problems. Resources are provided.
