Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

Build upon prior equation writing experience to create more complicated equations. Lesson one in a 33-part unit builds upon the class members' sixth and seventh grade experience of writing linear equations. Several examples...

Sometimes dealing with decimals is so much easier than dealing with fractions. The ninth activity in a 21-part module has the class consider situations when it might be easier to add or subtract fractions by first converting to...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Ratios may not be created equal, but they are equivalent. Pupils learn the theorem relating equivalent ratios and equal values in the eighth segment in a series of 29. Classmates use the theorem to determine whether ratios within...

Equivalent ratios show up on tape. Young mathematicians use tape diagrams to create equivalent ratios in the initial instructional activity on the topic. They learn the definition of equivalent ratios and use it to build others in the...

Once learners realize what direct variation is, they see it's just a type of linear function. The lesson poses a general question that leads to the creation of the y = kx formula. The resource includes discussion prompts and ideas for...

Class members create a table of the number of chords that can be drawn given the number of points on a circle. Pupils analyze the data created, find a function to fit to it, and use the function to make further predictions.

Students engage in a lesson that is about the concept of measuring the statistical data of a population taken from a census. The data is interpreted and recorded looking for trends in subjects like world economy and job opportunities.

Students demonstrate good random sampling techniques for data collection, select and develop graphic presentations of data and analyze the data to solve a problem presented.

Students solve theoretical probability problems. In this algebra lesson, students apply the concept of probabilities to solving real life scenarios. They collect data and graph it using experimental probability.

Students study the pumpkin. In this pumpkin instructional activity, students participate in different activities that explain the history of pumpkins and how pumpkins develop and grow, read "The Great Pumpkin Story" and answer...

In this mathematical expressions learning exercise, students solve 6 different problems that include deciphering various sets of numbers. First, they use any known mathematical operation or symbol in each to create the number 15. Then,...

High schoolers explore the concept of fractals. In this fractals activity, students use the website to research where fractals occur in nature. High schoolers research what fractals are and how fractals are used to solve real world...

In these math word problems worksheets, students complete five different math word problems using simple addition to solve the equations about food.

In this problem solving worksheet, students read a story problem about an animal shelter. Students then answer four problems about the animal shelter animals.

In this problem solving worksheet, students read a word problem about tadpoles and frogs and then complete three questions about the frogs life cycle changes.

Students solve systems of equations. In this algebra lesson, students use elimination and substitution to solve for the point of intersection. They use graphing to see where the two lines intersect.

In this proportions and ratios worksheet, students solve 6 short answer problems. Students find the foreign currency exchange rates for six countries. Students express the exchange rate as a proportion or ratio.

Sixth graders explore linear equations. In this linear equations lesson, 6th graders explore visual examples of 1-step linear equations. Students also practice solving problems that their instructors model.
