Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Students explore inequalities to determine the optimal solution to maximize a profit for a company. In this linear programming instructional activity, students discover how to graph inequalities and how to determine the algebraic...

Establish 1:1 correspondence by counting students, first one gender, then the other. Give each child a colored cube (one color for boys, another for girls) and have small groups determine more or less and how many all together. As a...

Early learners explore shapes using colored blocks. They first get some hands-on time with the blocks and then look at beginning math concepts regarding spatial relationships. They work with a partner to build a 6-8 block tower...

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...

Here is an inventive plan that should get your young scientists excited! In it, groups of pupils test out the work done by six different simple machines. The machines are: the wedge, the lever, the inclined plane, the pulley, the screw,...

From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

What happens to a function whose graph is translated horizontally? Groups find out as they investigate the effects of addition and subtraction within a function. This nineteenth lesson in a 26-part series focuses on horizontal...

Groups sort through NASA data provided in a graphic to create a graph using uniform units and intervals. Individuals then make connections to the increasing, decreasing, and constant intervals of the graph and relate these...

Does complex number multiplication have the class spinning? Here's a resource that helps pupils explore and discover the geometric effect of multiplying complex numbers. In the 14th installment in the 32-part unit groups look at the unit...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

Young cartographers in groups hide treasure at school and then create a map to find it using pattern blocks and tiles. They make paintings with clues to create a visual representation of the location of their treasure. Groups present...

Second graders identify a quarter, dime, penny, nickel, and dime. They match the coin with it's monetary value, collect data on excel spreadsheet, and create a graph in Excel. Students participate in group activities.

Students practice their multiplication facts by reinforcement and repetition. Students write facts in their math journals, and use labeled soccer ball and deck of cards to practice multiplying by "number of the day." Play continues until...

Some times a simple lesson is all you need. Here are 2 worksheets that can be used as a lesson on problem solving, addition, and partner work. The first worksheet has learners use a tens and ones charts to practice adding simple...

Children explore fractions on a conceptual level by making individual quilt squares. Each student works with small paper swatches to divide them into pieces that represent a given fraction. The class is then separated into groups and...

Multiplying fractions by whole numbers is the focus of the math activity presented here. There are three activities outlined in the activity along with a nifty game learners play on the computer that reinforces their learning. These...

Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...

At the end of this activity, your number crunchers will have a better understanding as to how to describe graphs of velocity versus time and distance versus time. It is easy for learners to misinterpret graphs of velocity, so have them...

Explore patterns in the multiplication table in order to deepen your third graders' understanding of this essential skill. Implement this activity as a whole-class activity, allowing students to work in pairs or small groups to support...

Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...
