After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

The battle of the sexes? Scholars first examine data on hurricane-related deaths and create graphical displays. They then use the data and displays to consider whether hurricanes with female names result in more deaths than hurricanes...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

After an introductory activity to demonstrate the theory of a limit, additional activities approach a limit from graphical, numerical, and algebraic methods. The activity looks at the multiple ways of understanding and evaluating a...

How very clever. No need to monkey around with this resource. Rob Cleveland's version of the West African tale, "The Clever Monkey Rides Again," is used as the basis for multiple of cross-curricular activities including exercises...

The national epidemic of opioid addiction is making its way into high school populations. Educate the students in your class about the ways prescription opioids can both block pain and deliver large amounts of dopamine that make it very...

Second graders write a Math Moments journal.

Transform your learners into master geometers with an activity that asks them to first complete an assessment task drawing the result after transformation of a given shape in the coordinate plane. They then use cards to...

There is more than one way to measure an amount, as learners discover by applying multiple measurement tools in these activities. Centimeter cubes, cylinders, beakers, and measuring cups are used to find the volume of regular and...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Working in small groups students develop three alternative boat designs. They discuss the rationale for the type of hull, propeller, location of ballast, and type of building material used in their design. They build their boat.

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...

High schoolers attempt an assessment task requiring them to find the radii of inscribed and circumscribed circles of a right triangle with given dimensions. They then evaluate provided sample responses to consider how to improve...

Young mathematicians join the ancient order of the Pythagoreans by completing an assessment task that asks them to find the area of tilted squares on dot paper. They then look at patterns in the squares to develop the...

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

Explore with your class the characteristics of acute, obtuse, right, complementary, and supplementary angles. They take digital photographs around the school and identify the angles in the images. Uisng software, they label and...

Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the...

Teach your class how to use descriptive statistics through a hands-on data collection activity. Pupils collect their own data, calculate test statistics, and interpret the results in context. They compare male and female results, looking...

Here is a lesson that takes an interesting approach to analyzing data using box and whisker plots.  By using an applet that dynamically generates Venn diagrams, the class forms a strategy/algorithm for guessing the rule that fits...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Develop probability distributions from simulations. Young mathematicians use simulations to collect data. They use the data to draw graphs of probability distributions for the random variable in question.

Students explore Earth science by participating in a weather identification activity. In this scientific instrument lesson plan, students identify several weather related tools such as the weather vane, thermometer and rain gauge....

Fourth graders engage in discussion of various occupations and learn where math fits into the scheme of things. They are diagnostically assessed to determine proficiency in computer, writing, and problem-solving mathematical skills set...

Students have fun with math. In this math skills lesson, students collaborate to solve the problems presented in this interactive lesson. The problems pertain to geometry, measurement, probability, number sense, and algebra.
