Curated OER
Shapes: Art or Geometry
Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.
Curated OER
Shape Hunt
Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...
Curated OER
Symmetry Using Polygons
Working on symmetry in your class? If so, this worksheet might be for you. Learners observe different triangles and quadrilaterals, determine which are symmetrical, draw in the lines of symmetry, and color the symmetrical shapes. In...
Curated OER
Geometry Shapes Playground Safety
Students create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...
Curated OER
Investigation: Area of Geometric Shapes
Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...
Curated OER
Making a Six-pointed Star
For this polygon worksheet, students identify and create a six-pointed star by completing 6 steps. First, they use a compass to trace a circle with a given radius. Then, students draw a point on circumference of the circle and place the...
Curated OER
Exploring Projective Geometry
For this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.
Curated OER
Three Dimensional Figures
In this geometry worksheet, students study diagrams with labels of common geometric figures. Students then answer 24 questions. Then they draw and label their own figures.
Curated OER
Lewis Structure Worksheet
In this chemistry worksheet, students draw the Lewis structures of 9 compounds and polyatomic ions, identify their molecular shapes and polarity.
Curated OER
Problem Solving Using Power Polygons
Pupils investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Pupils identify the different types of polygons and define their...
Curated OER
Angle Bisectors
In this angle bisector worksheet, 10th graders solve and complete 23 various types of geometry problems. First, they find the angles listed in the figure shown. Then, students determine the sum of the interior angles of a polygon. They...
Math Mammoth
Divide Polygons
In this geometry learning exercise, 3rd graders draw line segments into the shape and divide it into other shapes given. Then they divide the pentagon and hexagon in different shape parts using line segments. Students also write down...
Curated OER
Cubes and Cylinders
In this geometry worksheet, students identify cubes and cylinders by coloring a given number of each shape red, green, blue, or yellow.
Curated OER
Transformations
Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...
