Can You Make Quadrilaterals?
Students identify and describe squares, rectangles, parallelograms, trapezoids, and kites. In this quadrilaterals lesson plan, students put the quadrilateral shapes into a chart.
Curated OER
Squares
In this geometry worksheet, students color the pictures of objects that are shaped like squares. They choose between 11 pictures of items such as a heart, a window frame, a computer, and a coin.

Twisted Tangrams
Primary geometers create a picture using tangrams. In this geometry lesson, learners read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.
Curated OER
Applied Science - Science and Math (K) Lab
In this shape lesson, learners cut out tangram shapes and create different pictures with them. They look at 3-D shapes as well. There is a nice, hands-on component built into this lesson.
Illustrative Mathematics
All vs. Only Some
All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Grade 5: Testing for Tessellations
Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...
Curated OER
Pick's Theorem
Students investigate polygons and their lattice. In this calculus activity, students record data using different methods. They analyze their data and draw conclusions based on the relationship between the area and the interior lattice.
Curated OER
Matrix Transformations
Students perform reflections of polygons. In this algebra lesson, students use matrices to calculate the reflection across the x and y axis. They also calculate rotation representing 90 and 180 degrees around the origin of the coordinate...
Curated OER
Diagonals of Quadrilaterals
Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, students use the TI to create a visual of their shape.
