High schoolers investigate quadrilateral construction in this geometry lesson. They use Cabri Jr. to construct the different quadrilaterals from the quadrilateral hierarchy given minimal definitions. The lesson reinforces the difference...

Students identify the properties representing quadrilateral. In this geometry lesson, students differentiate between special and regular quadrilaterals. They discuss and demonstrate hierarchy of quadrilaterals.

Fourth graders discuss the various attributes of quadrilaterals. In groups, they use the attributes to sort quadrilaterals into different classes and a hierarchy. They review the new vocabulary and attributes with a partner to end the...

Students count amphipods under kelp wracks of varying ages to explain how long it takes for them to find their food source. They collect and represent the data.

Students practice using the request, response, result method to solve problems. Using one problem as an example, they break it down into multiple problems to be solved one at a time. They identify instances of hierarchical organization...

The house lights dim, the curtain parts, lights slowly come up, revealing the stage. Before the actors appear, before a word is spoken, the audience is drawn in by the lighting, by the colors, by lines of the set, by the props, and...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Students use Cuisenaire rods to explore common denominators. In this fractions lesson, students build Cuisenaire representations of fractions, then find their equivalent counterparts to find the common denominator.

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the activity develops the definition of a general cylinder. Scholars continue on to develop a graphical organizer...

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed instructional activity includes essential questions, vocabulary, a materials list, and links to related units.

Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Students examine the use of variable and ratio in everyday situations including figuring out the gear ratios for the gears on a 12 speed bike. They use the bubble sort technique to write a computer program which will determine the...

Ninth graders gain an understanding of Chaos Theory that exists in one's everyday environment.

Fifth graders use estimation to solve word problems. In this fractions lesson plan, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This...

Students using given data to extrapolate new information, using a linear equation to predict later behavior, and using previous knowledge to synthesize new conjectures.

Students pretend to purchase items at their class store using coins. At the store, they are to state the amount of the item they want to buy by reading the label. They give the cashier the correct amount of coins and are given a mark on...

Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson plan, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are...

Young scholars, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

This multimedia that includes a short video [1:19] and other interactive activities on Learn Alberta math resource looks at real-world examples of shape classification in the investigation and solving of crimes. The accompanying...

Students construct cyclic quadrilaterals and investigate their properties. They determine which quadrilaterals from the quadrilateral hierarchy are cyclic.

In this activity, students will explore the properties of the diagonals of various quadrilaterals. They will use a quadrilateral hierarchy chart to examine the relationship between the quadrilaterals.

In this activity, students will construct different types of quadrilaterals from the quadrilateral hierarchy. This activity asks for constructions based on a minimal definition of the quadrilateral. The activity will reinforce the...
