Learners use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.

Students explore basic building and engineering concepts by constructing a structure that supports weight. They demonstrate an understanding of basic business concepts by estimating the cost and value of a building.

In this decimal worksheet, students solve decimal problems, estimating, balancing a checkbook, and finding the cost of a car using a given chart. 

Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.

Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.

Pupils design and build a balance using LEGO, string, and a set of standard metric weights.

Students estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Students examine a cookie that represents pumice and lava in order to realize that lava is a composite of many rock particles. They compare and contrast pumice to the cookie by estimating, weighing, measuring and dissecting the cookie...

Students estimate how many peas fit in a container. In this science lesson, students calculate the weight of a pea and record it. They use this data to calculate how many peas fit in a human brain.

Students identify the characteristics of a bridge and build with junk materials.  In this bridge building lesson plan, students use cereal boxes, paper towel or toilet paper tubes and tape to create their bridges.  Bridges...

In this simple past tense activity, students use words and phrases given to form positive sentences in the given tense. Answers may be submitted online for review. ESL appropriate but not exclusive.

Two learners are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of polygons....

Young scholars experiment with the cohesion of water molecules. For this surface tension lesson, students estimate how many drops of water a full glass can take before overflowing. They watch a video that explains water molecules.

Fifth graders arrange the classroom using all the moveable objects and through the exploration of area and perimeter. They determine the area of the classroom, create and label model pieces of furniture using graph paper, and create a...

Students investigate shapes as the area changes while the perimeter remains the same. Students demonstrate the shape/perimeter/area relationship using simulations and physical models.

Students use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date. They analyze the data for each map and corresponding text file to determine an estimate of snow cover...

Learners match definitions with vocabulary words and learn basic facts about matter. Then, they see how to determine the physical characteristics of matter. They determine the mass, volume, and density of objects using appropriate tools...

Students create a time capsule. In this time capsule lesson, students collect and record data about themselves to be stored in a time capsule that will be opened at the end of the year. 

Young scholars define matter, the chemical properties of matter, and the physical properties of matter. They name physical and chemical properties of matter (by classifying using a Tree Map). Students determine the mass, volume, and...

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Second graders determine when estimates and exact totals are appropriate in dealing with money. They simulate keeping a checking account over a period of time and keep a checkbook ledger to record deposits and expenses.

A huge collection of teacher resources to aide in the teaching of all types of metric measurement: length, distance, mass, weight, capacity, and volume. Activities include measuring, estimating, converting, investigating, and finding...
