Third graders investigate two mathematic scenarios and determine which is correct. They compare adding columns and places (such as the tens place, hundreds place, and so on) and familiarize themselves with how to add larger numbers.

Help your class make sense of quantities and their relationships. Given is the product of two numbers. It is up to your number crunchers to think about the quantitative relationship when the product is one-tenth or ten times the product...

Using a varity of strategies, young mathematicians solve multistep word problems. They play a logic game as a whole group, and then work with a partner on a computer to complete a worksheet that requires a variety of problem solving...

Students read about and discuss how chemical engineers use different states of matter to create substances. In this chemical engineering lesson plan, students also give examples of the 3 kinds of matter.

Let the resource stretch the minds of your young scientists with a lesson about tensile strength and stiffness of materials. Groups consider how easily materials stretch and relate this property to engineering design.

Solve systems of equation problems using four different methods: elimination by addition or subtraction, graphing, elimination by multiplication, and substitution. Middle schoolers are then given a series of "missions" to complete.

Students examine bone fractures and the role that engineers play in repairing them.  For this biomedical engineering lesson students describe the factors that engineers consider when designing devices. 

Sixth graders listen to Demi's, On Grain of Rice: A Mathematical Folktale. They use the problem solving strategy of finding a pattern to determine the number of rice Rani will receive after 30 days. They create a spreadsheet which...

Students explore the concept of adding and subtracting integers. In this integer lesson, students use strips of paper (various sizes) to add and subtract integers. Students visualize the process of adding and subtracting integers.

Young scholars explore the concept of multi-step equations. In the multi-step equation lesson, students solve equations by the 'party method'. Young scholars make a flip book that shows the steps in solving multi-step equations.

Middle schoolers practice calculating the slope of a line. They explain how the formula is derived and identify properties that are associated with positive, negative and undefined slopes. They complete an online activity as well.

Twelfth graders solve first order differential equations using the separation of variables technique. In this calculus lesson, 12th graders explain the connection between math and engineering. They brainstorm what engineers do in real life.

Students cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Students examine the health risks of radon in the home. They calculate the odds for each risk and use different forms of measurement. They work together to complete the activity and worksheet.

Students investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and debits.

Students use rounding and compensating with whole numbers and explain how to use the empty number line to show additions and subtractions. They round and compensate in relation to decimal subtraction Background
