First graders examine the use of number lines in problem solving situations in this series of lessons. They participate in activities in which they move forward and backward on number line on the playground before doing paper and pencil...

Learners analyze the advantages of regular saving and how savings grow with compounding. After reading the story "The Hundred Penny Box", students define the terms "interest," "interest rate," and "compounding." Through several...

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

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...

What happens when combining percentage discounts? The last instructional activity in a series of 29 introduces the idea of combining discounts one after another. Pupils wrestle with the claim that to find the total discount, they...

Young mathematicians view a video on solving quadratic equations by factoring. They use this skill to complete a learning exercise of practice problems — a great way to gauge understanding!

Fly through graphing functions with the Function Flyer. Young mathematicians use an interactive to graph different types of functions. A set of exploration questions has users investigate patterns in functions.

Why do I have to do bean counting if I'm not going to become an accountant? The 24th installment of a 35-part module has the class conducting experiments using beans to collect data. Learners use exponential functions to model this...

Students measure their classroom and determine the area. They discuss the margin of error. Each class member will write up their results separately. Students must decide what measurements to make, and attempt to measure accurately.

Students demonstrate an understanding of the properties of matter by applying them to density, pressure, and temperature. The educational software program, "Foilsim" is used in this inquiry.

Students use FoilSim to design an airplane wing that generates a given lift. As they change parameters such as airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software...

Students select and use appropriate operations, methods and tools to compute or estimate using whole numbers. They develop and use formulas for determining the circumference and area of circles. Students determine and describe the...

Students examine the concept of perimeter. Students calculate the perimeter of a random shape on a grid. Students develop a better understanding of the concept of perimeter. Students calculate the perimeter of shapes.

Students use the FoilSim educational software program to complete an activity regarding lift. They solve a multivariable equation for each of the variables and apply the results to various problems in different situations.

Students, in groups, design and construct an air car capable of acceleration. They view a video on acceleration, test their cars and make adjustments as desired.

Third graders review telling time. In this lesson on telling time, 3rd graders discuss various items that show length of time, including clocks, calendars and sand timers. Students review and practice what they already know about telling...

Learners determine the vertex, y-intercept and direction of a parabola and write an explanation of how to graph a parabola. They collect and graph data using a calculator.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...

Students discover the concept of elapsed time. In this calculating time lesson, students utilize the Internet to complete record sheets based on the concept of elapsed time. Finally, the students answer questions on their own.

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

Students creating chords intersection using circles. In this geometry lesson, students create visuals of chords ad their properties using Cabri technology. They measure the chords and explore the relationship among chords.

Students use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.

Third graders build a periscope and experiment with it to determine how this tool helps them extend their line of sight.
