Students make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

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

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...

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...

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

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Fourth graders are introduced to the problem by weighing objects on the balance scales. Use weights in both pans. (If you don't have access to scales use 2 containers and a child acting as the balance.) They then listen to the problem...

Pupils investigate a small business and its profitability. In pairs, as they research a business adventure, students consider the capital outlay, maintenance, office space, prices, insurance, and profit and loss statements. Pupils design...

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students solve problems. In this math lesson, students write solutions using LOGO commands in order to help get the turtle to the pond.

Students choose the correct strategy to solve multiplication and division. In this algorithm lesson, students use at least two strategies that use properties of operations and estimation. Students also recognize the relationship between...

Students use graphs to calibrate an RCX car. They must then program the car to traverse a maze using their calibrations

Students view a demonstration that simulates cloud formation. They read a poem about clouds, participate in a class demonstration using warm water and ice and write a paragraph summarizing their observations.

Students differentiate triangular prisms from other prisms using nets. In this geometry lesson, students define the properties of a triangular prism and its symmetry. They build a triangular prism moving lines around.

Learners sketch the shape of three dimensional pyramids using nets. For this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Students 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.

In this geometry worksheet, learners identify the interior and exterior angles of parallel lines cut by a transversal. There are 11 questions with an answer key.

Students examine how materials oppose the flow of an electrical current.  In this resistivity lesson students complete several experiments on the differences between resistance and resistivity.

Students create a spreadsheet that calculate the amount of concrete needed to pour various concrete forms.

Students collect as much information as possible about their egg and record the information in a systematic way. They prepare a description of the egg your team was given that enable you to distinguish your egg from everyone else's egg.

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may submit their answers to be scored.

Students work collaboratively to design and construct a roof out of Legos for a house that was built in a previous lesson plan. The roof must be structurally sound and pass certain criteria determined by the teacher.
