Students find the factor of proportionality in similar polygons. In this similarity of polygons lesson plan, students measure the sides and angles of polygons and derive a factor of proportionality between corresponding pairs of sides...

In this algebra worksheet, students manipulate integers to add, subtract, multiply and divide using order of operation. They rewrite word problems and solve for the unknown. There are 24 questions with an answer key.

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 circle learning exercise, students solve 8 problems: finding percentage increase, finding differences in area and perimeter, finding circumference and area.

Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...

Middle schoolers discuss how big is big. They compare the area and perimeter of an acre and a football field.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

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...

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

In this geometry math review learning exercise, students respond to 37 questions that serve as a review of geometry skills.

Students create a rectangular garden using paper and tiles. In this geometry lesson, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the rectangles creating a...

Fifth graders build models. In this measurement lesson, 5th graders build paper models to represent square centimeters, square inches, square feet, cubic centimeters, cubic inches, cubic feet, and perimeter.

Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...

Third graders use whole numbers and fractions to make connections between abstractions of the mathematical world and the real world. In this fractions and measurement lesson, 3rd graders identify, quantify groups , and measure distances....

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.

In this statistics instructional activity, students solve word problems using their probability and how many times an event may or may not occur. This instructional activity contains 54 questions that are all word problems.

Young scholars discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e.,...

This hands-on instructional activity takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable...

Students solve word problems by using basic geometry. In this geometry activity, students use geometric formulas to find the perimeter, area, and volume of objects. Students complete a worksheet.

Sixth graders apply problem solving strategies to work with a real life situation in which they need to determine the area. They determine the area of chicken runs that are rectangular in shape when give a partial perimeter.

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry lesson, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and spheres. They...

In this mental math instructional activity, students calculate area, volume, perimeter, and convert units in two mental math tests of ten problems each. 

Pupils identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.
