Students practice doubling the numbers one through five while viewing a projected computer activity using MathKeys software. They stamp numbers onto an activity sheet that corresponds to the number of objects on the screen and then write...

Students compare, resize, and check various shapes by size using a comparison mat from the MathKeys program. Working in pairs, they place three similar shapes on the screen and state which is the largest and smallest in area. They also...

Fourth graders investigate the concepts of area and perimeter, and they practice finding the values in various types of situations. They construct different representations of shapes using the area measurements and also explain the...

Students build two, three, and four digit numbers using base ten blocks and round those numbers. In this rounding numbers lesson, students work in pairs and build numbers using base ten blocks.

Sixth graders identify parallel and perpendicular lines in the alphabet. In this line properties lesson, 6th graders use the letters of the alphabet to show parallel and perpendicular lines. Students open a Geogrid Mat on the computer...

Students analyze the measurements of rectangles. In this analysis lesson, students will investigate patterns by looking at ratios. Students will also hypothesize the probability of a ball going into a certain pocket when playing pool....

Young scholars identify various sources of income and discern between needs and wants as they also learn to create a personal budget.  In this personal budget lesson, student understand financial scenarios as they relate to...

Sixth graders determine whether Nabico's claim to sell 1000 chocolate chips in every 1 pound bag of Chips Ahoy! is true.

Students research data and develop statistical methods such as mean and median price and make convincing arguments as powerful ways for decision making.

Sixth graders explore the relationship between area and perimeter of rectangles. In this area and perimeter lesson, 6th graders measure and determine perimeter and area of various rectangles. Students create rectangles with given areas...

Students practice calculating the perimeter of different sized rectangles. Individually, they identify the derivations of a function that can show the perimeter and determine how to minimize the perimeter within a fixed area. They use...

Students are introduced to the concept of perimeter. As a class, they listen to a lecture describing the derivations of a function that describes perimeter. They calculate the minimum perimeter of a rectangle and determine the numbers...

Students explore the concept of coordinate proofs. For this coordinate proofs lesson, students write coordinate proofs using properties of distance, slope, and midpoint. Students discuss why it is sometimes beneficial to double the...

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Middle schoolers investigate the analytical processes used to interpret the 2001 Canadian census. They examine the population statistics and trends.

Students measure the angles of wings and tails of various aircraft using a protractor. They estimate and check their measurements. They investigate aircraft being developed and tested at NASA Dryden.

Young scholars explore the world of mass transit and how it affects their community as well as how it attempts to reduce our pollution mass. Included as well are the environmental and social factors relating to mass transit. They read...

Students make predictions based on survey results. They calcuate sample proportions. Students estimate the number of voters in their district preferring the democratic candidate using their sample results. They review sample proportions...

Students engage in a lesson for mathematical application based upon the use of calculations in order to create a fence for a volleyball court. The fence is designed and drawn with measurements. The core of the lesson is the calculation...

Elementary schoolers explore the concepts associated with comparison shopping, and the concept of need versus want. They also look closely at the power of advertising and become more aware of the messages that ads present. After taking...
