In this tessellations instructional activity, 10th graders solve 6 different types of tessellation problems that includes drawing. First, they define polygon, regular polygon, tessellation, regular tessellation, and semi-regular...

Third graders represent fractions as part of a whole. In this fractions activity, 3rd graders use manipulatives to show how a fraction is a part of a whole. This activity includes individual practice and an assessment instead of direct...

Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...

Here is a well-designed lesson inviting learners to consider the qualities of a hero. They describe the lives and deeds of national, state, and/or local heroes. This is a thoughtful lesson, which is part of a sequential group on heroes....

In this shoelace algorithm worksheet, students determine the area of a triangle when given the coordinates of the vertices. They determine the area of a quadrilateral. Students find the average of the x and y coordinates.

Students explore quilting. In this math patterns lesson, students define the perimeter of a quilt border, create tessellations using geometric shapes, and detemine the area of a quilt.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

In this plane geometry worksheet, students combine the basis of plane geometry and linear problems to solve problems. They determine total surface area, the length of a line, and the sum of the edges of a three-dimensional figure. This...

Your young learners will enjoy having quick access to this reference sheet that includes a multiplication chart, formulas for perimeter, area, and volume, place value chart, fraction chart, basic types of polygons, triangles and lines...

Learners participate in a hands-on activity that shows the independence of perimeter and area for simple irregular figures.

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...

This discussion based lesson focuses on the sensitive topic of suicide attacks or bombings used throughout history during times of militaristic upheaval. Learners read news stories, compose journal entries, and engage in a class...

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

Learners experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Students develop their awareness that straight line segments can produce the illusion of a curve and helps them recognize and describe number patterns and geometric fundamentals.

Take graphing outside and make a giant coordinate plane to plot your human points. Young graphers are each given a coordinate for a particular shape and asked to make the geometrical shapes one by one. Those not plotted are to write down...

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students identify geometric patterns in quilts. In this geometry lesson, students view various types of quilts and identify the geometric shapes. Students construct one hundred patch paper quilts using geometric shapes.
