Students investigate where a new element would be located on the periodic table. In this isotope instructional activity, students find the mass of a new element, people mass. This number will be entered onto the periodic table of...

Second graders, in groups, prepare a list of proposed record ideas for the class book.

Students practice continuous probability distributions. In this probability lesson, students calculate probability, use probability functions, and use rectangular distribution.

Eighth graders experiment with M&M's and a cup attached to a spring to to simulate a bungee jump. They graph the results of the experiment and make predictions for continuing the experiment. They determine the "line of best fit."

Fourth graders, acting as foresters, determine timber volumes as sawtimber or pulpwood for marketing. They find the marketable value of a tree using its diameter and volume.

Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.

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.

Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...

In this mathematical worksheet, learners convert fifteen metric units of capacity and multiply and divide whole numbers by 10, 100 and 1000.

Students design a "container" for his/her egg to determine whether the egg remain intact when dropped from a predetermined height.

Second graders design a successful kite for Kite Day.

Pupils use four different computer estimation applets with several classroom estimation activities.

Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

In this number averages worksheet, students review how to find the average of a given set of numbers. Students then complete three word problems by averaging numbers.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...

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.

Eighth graders investigate Newton's Law of Inertia in order to create a context for the review of the use of different types of graphs. They practice gathering the data from an experiment and put it into the correct corresponding graph.

Learners determine the area of two objects by superimposing one on the other. They compare and order the area of different shapes by covering a larger shape with similar smaller ones. They complete these activities as different stations.

Young scholars study the techniques of building a bridge. They explore different type of bridges and then plan and build a bridge to specified instructions. Students draw plans, keep a budget, and prepare balance sheets during their...

Students review and reinforce the concepts of mean, median, and mode based on the number of siblings the students have. They use Post-it notes to organize and re-organize the data.

Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.

Students problem-solve how to log five acres. Working in pairs, they construct models of logging sites before and after the trees are harvested. they paint their models and include other environmental details.

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...
