Most problems can be solved using more than one method. A worksheet includes just nine questions but many more ways to solve each. Scholars must graph, solve, and justify quadratic problems.

Clever! Participants don square-foot cardboard shoes to mark out the rain garden plot that they have spent the last few weeks designing. In this way, they are practicing scale modeling as well! Note that this lesson is part of a unit,...

You've got to pump it up! Using the equations for projectile motion and Bernoulli's Principle, class members calculate the water pressure in a water gun. The pupils collect data on the number of pumps and distance traveled in order...

From z-scores to probability. Learners put together the concepts from the previous lessons to determine the probability of a given range of outcomes. They make predictions and interpret them in the context of the problem.

To examine mathematical functions in a modeling situation pupils combine quadratic and step functions to represent a presented scenario. They both graph and write a function to represent data shown in a table. 

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Wrap up a lesson on surface area with a resource that asks scholars to use the idea of wrapping paper to investigate surface area. They draw representations of rectangular prisms on graph paper to find the areas of the respective...

How does your garden grow? Use proportions to help Tim answer that question. By using their understanding of proportional relationships, pupils determine the number of seeds that will sprout. They create their own linear...

Where is the point? Given three points on the coordinate plane, the video walks through the steps to find the location of the fourth point to create a given special quadrilateral. The narrator first determines the coordinates of the...

Designs from lines are sublime. Scholars create colorful designs by connecting points on an interactive coordinate plane. They answer questions about slope and quadrants based on their designs.

Scholars show what they know about data collection and analysis with an activity that examines a smaller population of Houghton, Texas. Independently or in pairs, learners identify their research question, gather, graph, and analyze...

What function will describe the insect population growth? Pairs or small groups work together to determine which type of function and specific function will model given scenarios. The scenarios differentiate between linear,...

Eleventh graders analyze a chart comparing U.S. census data from 1850, 1880, 1900, and 1920. They read a handout summarizing immigration legislation from 1882-1996 and create a graph charting how open / closed U.S. immigration is over time.

What if the Gingerbread Man was trying to catch you, rather than the other way around? Pupils can find out what happens by reading the story The Gingerbread Man Loose in the School by Laura Murray and enrich their experience with the...

Who's driving that car? Science is! Through a simulation, learners adjust the magnitude and angle of motion on a driverless car. Two different motions create a resultant motion. Vectors represent the motion and graphs depict the...

How reliable is a painting of the first Thanksgiving if it was created 300 years after the fact? Learners assess the validity of a primary source image to determine what it can actually reveal about this event. 

Students conduct experiments with plants.  For this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

Students analyze ozone data.  In this atmosphere lesson, students will use a NASA resource to gather data for different regions of the Earth.  Students will then create a graph for their data and answer related questions. 

Start with the basics. Pupils work through a review of the unit on equations and inequalities. Learners begin with solving equations and inequalities with no context, move on to problems that involve a context, and finish with a...

Not all species can survive in all habitats. Using specific criteria, learners assess the fitness of a local habitat to a specific species. They collect data and suggest enhancements to create a suitable habitat for their chosen species.

What more could we want from floor tiles? Using pattern blocks and graph paper, pupils determine ways to completely tile a floor of given dimensions. They consider the aesthetic quality of the tiles by creating a tessellation and...

What would a three-dimensional representation of Bloom's revised taxonomy of the cognitive domain look like? Get a glimpse of the complex classification system that is frequently referenced in education to distinguish levels of...

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

Build a soccer field through a little mathematical analysis. Individuals manipulate the dimensions of a soccer field as they drag points to new positions. The simulation shows the corresponding intercepts and area. As pupils explore the...
