Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

An outstanding instructional activity on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about...

Inntroduce primary learners to essential critical reading strategies with an activity based on James Reeves' poem, "The Wind."  Learners listen as the poem is read, first as a riddle, and then re-read with the title visible. The...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Mathematicians utilize artwork to help illustrate the major ideas of transformations and tessellations. They visually identify transformations including reflections, rotations, and translations. They discuss how artists have used...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

It is a-maze-ing how lost one can get. Teams reconstruct a simple maze and solve it. Participants create an algorithm that a robot would follow in order to solve the maze as well. The activity includes an extension directing pupils to...

Solve a maze ... from a robot's point of view. In the lesson, your scholars build a small, simple maze from cardboard and then find a route from the start point to the finish point. They write an algorithmic process that a robot could...

Given a box of certain dimensions, young mathematicians must determine if a box that is twice as big, actually holds twice as much. This is a brain-teaser of a problem. The worksheet provides a handy table that has learners calculate the...

Here is a challenging and thought-provoking math instructional activity. In it, learners work together to construct a variety of boxes of different sizes to see if doubling the size of a box really means it can hold twice as much stuff...

Fifth and sixth graders work alone or in pairs to determine the volume of paper boxes of various dimensions. Pupils write ratios of dimensions and volumes.

Students use a monochromatic palate, select shades and tints for a selected hue, or select complimentary or analogous colors for a quilt design. They design quilt squares using basic geometric shapes, repetition, balance, and proportion.

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

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.

Students classify polygons by name and shape. In this geometry activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

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...

Pupils study pyramids. In this prisms lesson, students explore the attributes of pyramids. Pupils will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.

Students investigate and solve Pythagorean triples. In this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.

Students investigate the Pythagorean triples. In this geometry instructional activity, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Students study basic concepts necessary to produce beautiful, professional looking visual compositions (which can then be used in professional television productions).

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...
