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 instructional activity in a 26-part series focuses on...

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.

Young scholars 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...

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

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 lesson plan presented here. There are three activities outlined in the lesson plan along with a nifty game learners play on the computer that reinforces their learning....

The commutative property of multiplication applies not only to whole numbers but to fractions as well. Connor and Makayla explore and discuss the idea that 2/3 x 3 is the same as 3 x 2/3. Your 5th grade class will connect with...

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 lesson, allowing learners to work in pairs or small groups to support...

Under which conditions can a triangle be classified as isosceles? High schoolers practice identifying isosceles triangles and special line segments, including angle bisectors, medians of triangles, and perpendicular bisectors of sides of...

After viewing a video on fractional amounts, young mathematicians put their new knowledge to the test. Throughout the assessment, class members find the fractional amount for prices, times, and populations. There are a few percent and...

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...

Can you determine how far down a rock drops without visual clues? Viewers observe a clip from a movie testing vertical distance only based on sound. They must determine if it is safe to drop down themselves or if it is farther than their...

Introduce pupils to the two types of reasoning, inductive and deductive. Classmates work in pairs or small groups to learn the difference between the two and apply these reasonings to develop valid conclusions.

Multiplying with multiples of 10, 100, and 1,000 provides an opportunity to discuss patterns that arise with zeros. The class uses these patterns to solve problems. Then they rotate through three work stations, including a computer-based...

Students work in a group to prepare a poster about a new number system. They research a variety of number systems, create new symbols for their original number system and develop a tutorial for the class.

Fifth and sixth graders practice working in pairs to determine whether they can walk with constant speed. They test themselves, collect their data, draw graphs with their data collected, manipulate the data, and then draw conclusions...
