Students explore basic shapes concepts. In this math lesson, students examine circles, triangles, squares, and rectangles as they draw the figures they see on worksheets.

Fifth graders solve word problems. In this math lesson, 5th graders read the word problem and determine what is being asked. Students solve the problem and explain how they reached their solution.

In this simple math lesson plan, 6th graders complete problems where they divide fractions which use one digit numbers in the numerator and denominator. At first, students work independently. Then, student groups come together to compare...

Students explore the math concept of sequencing. In this math lesson, students examine patterns and determine the patterns needed to finish sequences.

Fifth graders study perimeter. In this math activity, 5th graders use Cheerios to find the perimeter of various polygons. Students discuss how to figure the perimeter of triangles, squares and rectangles.

Ninth graders design a safe passage through a 2-D obstacle. For this geometric math lesson, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students will work in...

Students explore grouping. For this math lesson, students brainstorm ways to efficiently count the items in their pile and discuss the methods used. Students use a place value chart and practice regrouping ones to tens.

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Class members come up with a hypothesis on the number of decimal digits in the product of two decimals. Learners work in groups to complete several decimal multiplication problems. The results help groups develop a conjecture on the...

Scholars learn to divide multi-digit numbers using the standard algorithm in the 14th installment in a module of 21 parts. They get plenty of practice with the algorithm by completing a worksheet.

Represent ratios using a variety of methods. Classmates combine the representations of ratios previously learned with the coordinate plane. Using ratio tables, equations, double number lines, and ordered pairs to represent...

Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...

Help your charges solve a variety of fraction and skip counting problems using a problem solving process. As a class they work through a fraction problem step-by-step, and discuss a real-life connection to the problem. Students then play...

Pupils continue the study of ratios by creating ratios from a context. The contexts present more than two quantities, and scholars create contexts that match given ratios. 

It's time to get crafty with shapes! Your future farmers demonstrate their geometric ability by building a farm using triangles, circles, rectangles, and squares. But first, scholars take part in a brainstorm session inspired by their...

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

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.

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

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

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

They say you can interpret statistics to say what you want them to. Teach your classes to recognize valid experimental results! Pupils analyze experiments and identify flaws in design or statistics. 

How do you solve for an unknown angle? In this sixth installment of a 36-part series, young mathematicians use concepts learned in middle school geometry to set up and solve linear equations to find angle measures.

Drawing circles isn't the only thing compasses are good for. In this first installment of a 36-part series, high schoolers learn how to draw equilateral triangles by investigating real-world situations, such as finding the location of a...

More constructions! In this third installment of a 36-part series, learners watch a YouTube video on creating door trim to see how to bisect an angle. They then investigate how to copy an angle by ordering a given list of steps.
