Problem Solving Using Pattern Blocks
Students use pattern blocks to create a figure that is described to them and establish a pattern based on the description of the geometric figure. In this pattern blocks lesson plan, students fill out shape and fraction worksheets.
Curated OER
Lines of Symmetry
Fourth graders identify lines of symmetry using reflections and then construct figures that have one or more lines of symmetry. In this symmetry lesson plan, 4th graders use sets of shapes, pattern blocks, a mirror, and more.
Curated OER
Decode Word Is..
Students solve problems using patterns. For this algebra lesson, students identify the relation, domain and range of a function. They graph functions using coordinate pairs.

Modular Houses
Students, working in pairs, are presented with the problem. They are asked to design modular houses using four cubic modules, all the same size, which touch each other on complete faces. They must draw each of their houses on isometric...
Curated OER
Lines, Rays, Line Segments, and Planes
Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes
Curated OER
Irregular Fractals
Students explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. Students calculate fractal dimensions of various fractals.

Creating Polygons
Learners describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Round to the Nearest Whole $
For this rounding money worksheet, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.
Curated OER
Building Buildings
Learners work together with a partnet to design a building. Using materials, they create the inside and outside of the structure along with works of art. They present their creation to the class and receive constructive criticism in return.
Curated OER
Angle Pairs
High schoolers practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.
Curated OER
Symmetry: Theory, Reality and Art!
Young scholars explore the concept of geometric symmetry. In this geometric symmetry activity, students walk around their school and take pictures of objects that demonstrate symmetry. Young scholars use Microsoft Paint to draw the lines...
Curated OER
Congruency Basics
Fourth graders investigate congruent shapes. In this congruency instructional activity, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.
Curated OER
Pythagorean Theorem Proof
Tenth graders investigate the Pythagorean Theorem. Then they type up a formal paragraph proof of a proof of their choice.
Curated OER
The X-33 and the X-38
Learners explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.
Curated OER
Cut, Construct and Think 3
Students identify and create shapes. In this geometric shapes lesson, students identify various polygons and try to create new shapes using existing polygons.
Curated OER
Cut, Construct and Think - 4
Students identify polygons. In this geometric shapes lesson, students identify and describe polygons. Students create new shapes out of the shapes they are given.
Curated OER
Cut, Construct and Think - 6
Pupils identify polygons and calculate perimeter. In this geometric shapes lesson, students complete a worksheet identifying various polygons and calculating the perimeter of triangles and quadrilaterals.
