In this math worksheet, students investigate inequalities using problems like: If x and y are randomly determined so that 1 < x < 3 and 4 < y < 7, then what is the probability that | x – y |< 4?

Young scholars are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three...

Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

In this algebra worksheet, 11th graders solve 14 systems of equations using substitution or elimination and 14 word problems.

In this area and perimeter worksheet, students read the instructions and study the examples to learn how to find the area and perimeter of a square. Students solve 30 problems. This page is intended as an online activity, but may be...

Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Students create two drawings for a new animal pen design at the zoo. They must draw the ideas keeping the amount of material available in mind. They compare and contrast their two designs and write how they are similar in perimeter and...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Fifth graders calculate the perimeters, areas, and volumes of everyday objects. They discuss the word problem involving Puck from the Shakespeare play "Mid-Summer Night's Dream," and invent and plan a method for solving the problem in...

Dominoes, polyominoes, tetrominoes, and pentominoes are the subject of this interesting math activity designed for middle schoolers. Pupils cut out shapes that are embedded in a worksheet in the plan, and experiment with them by...

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Loaded with concepts ranging from multiplying decimals to converting units to solving problems using the order of operations, a thorough practice packet is perfect for a fifth or sixth grade math classroom.

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Communication is the key. A presentation provides 25 sample items for Claim 3, Communicating Reasoning, for the Smarter Balanced High School Math assessment. Items require pupils to answer the question and provide logical reasoning to...

Students investigate circles using a BMX path. In this circles lesson, students use technology of various kinds to create a BMX track. They use Moodle to develop their lesson and as they investigate the area and perimeter of a circle....

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

In this number sense activity, 5th graders solve 37 problems based on a given number. Students are asked to round the number, identify the number as even or odd and add 100 to the number.

Students practice recognizing shapes while using gross-motor skills. In this early childhood math movement lesson, students explore shapes as music plays and they walk the perimeter of large cut-out paper shapes by playing musical squares.

In this function worksheet, students find the slope of a line tangent to a given graph, they derive formulas for the area and perimeter of a given right triangle, they graph functions, and compute the derivative of functions. This...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...
