This optional lesson introduces the class to the idea of a minimum spanning tree. The activity focuses on determining an algorithm that will find the most efficient path in a network to transfer data. 

Count the connections between dots. Young mathematicians come up with a method to determine the number of connections between pairs of dots. The assessment leads the class to determine the connections they can make when groups are...

Teach the ins and outs of the cube! A series of five K–12 level activities explore the make-up of the cube. The beginning lessons focus on the vocabulary related to the cube. Later lessons explore the possible nets that describe a cube....

In this Geometry worksheet, 10th graders solve problems involving the properties of a regular pyramid.  The one page worksheet contains two multiple choice questions.  Answers are included. 

Two students 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....

In this math activity, learners are asked to used a compass and straight edge to construct copies of shapes, angles and line segments.

Students explore geometry using a Rubik's Cube. In this 2-D and 3-D shapes instructional activity, students use the Rubik's Cube to find the center, edge and corner pieces. Students then find the dimensions of the Rubik's Cube and read...

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.

Students explore kite making.  In this cross curriculum fine arts and ancient Chinese history lesson, students activate prior knowledge about how kites were used in ancient Chinese culture.  Students sketch an original kite...

In this geometry worksheet, 10th graders construct parallel and perpendicular lines using a compass and a straight edge. There are 4 construction questions with an answer key.

In this geometry worksheet, students construct parallel and perpendicular lines given a straight edge and a compass. Their lines pass through a given point. There are 4 questions with an answer key.

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Genetics learners read an article and watch a video about personalized medicine and the hope it holds for treating patients more specifically than doctors currently are able to. They research, design, and produce a brochure about the...

Avi's Crispin: The Cross of Lead is the focus of a teacher's guide that provides background information on 14th Century England, a plot summary, discussion questions, activities, and resource links. A must-have for those who use this...

Students explore a variety of methods used to finish quilts. They explore selection, planning, and the design process, color, proportion and scale when finishing a quilt. Students create corner triangle borders, narrow borders, pieced...

Students participate in a variety of activities about endangered animals. They read books, watch videos, and, in pairs, choose an endangered animal to research. They create a 2 slide presentation to be compiled into a class slide show.

Students decorate the congruent faces and edges of boxes in exactly the same way. They teach the terms "congruent," "faces," and "edges" to their parents.

Learners identify solid figures. In this classification lesson, students recognize and name solid figures. Learners identify which figures contain polygons and rectangles. Students practice counting vertices, faces and edges.

Students explore space shapes learning about edges, corners, and faces. They enjoy shape soup as a culminating activity.

In this attribute of solid shapes reteaching worksheet, 1st graders review the meaning of faces, corners, curves, and edges. They complete 8 examples by circling the curves, faces, edges, and corners on the given shapes.

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students construct the viewing tubes by cutting along the designated line shown on the template, rolling the paper into a tube, and taping the tube securely. Next they cut out the cardstock circles - the StarCards cutting on the outside...

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...

Fourth graders, using a straight edge, determine whether a point is inside or outside of a given figure. With worksheets, 4th graders practice analyzing geometric relationships such as parallel to, perpendicular to, etc.
