Tangram Cutout
Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Shapes
Students identify attributes of different geometric shapes. In this geometry lesson, students view a PowerPoint presentation on shapes and use attribute blocks to examine the corners and edges of each shape. Students work together to...

Branding Circles, Squares, Rectangles, Triangles
Compare and classify 2-D shapes! Kindergarteners inspect the attributes of plane shapes and examine shapes in everyday life. They label the circles, squares, rectangles, and triangles they find. This is the website where you can find the...
Curated OER
Cutouts
Students identify symmetry in shapes. In this geometry lesson, students fold paper to identify lines of symmetry. Students create various symmetrical shapes using folded paper.
Curated OER
Geometry
Learners are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...
CK-12 Foundation
Polygon Classification
Polly want a polygon? Young mathematicians sort shapes using an interactive. They classify the shapes as convex polygons, concave polygons, or not polygons.
Curated OER
Geo-Critters (Geometry Critters)
Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry lesson, students identify geometric shapes and their properties. Students create a geo-critter.

Geometry and Islam: Religious Beliefs Made Visual
Students examine the importance of geometric patterns in Muslim countries. Using cutout patterns, they replicate the designs seen in Islam and color them. They put their completed designs on a bulletin board to show to the school.
Curated OER
Folding Shapes; Are the Sides the Same?
Second graders explore geometry by experimenting with fold-ables. In this geometric shapes lesson, 2nd graders utilize cutout shapes from construction paper which they experiment with by folding. Students examine the symmetry and...
Curated OER
Area of Combined Shapes - Turtle Combo
Students graph polygons using the name and number of sides. In this geometry lesson, students identify the formula to calculate the area and perimeter of polygons. They relate the formula to different polygons and shapes.

Transformations
Geometry in life-sized dimensions! Using enlarged graph paper, pupils perform a series of transformations. By recording the initial and final placement of the images, they are able to analyze the patterns in the coordinates during a...
Curated OER
Shapes...the Beginning of Geometry
Students identify and name basic shapes and points. In this elementary geometry lesson, students use printable cut outs to name circles, triangles, and squares before playing a game with them. They play a game of "Pin the Tail on the...
Math by Design
Transformations – Reflections
Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...
Curated OER
Dissecting the Cube
Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Properties of Area
What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.
Curated OER
Tango's Story
Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.
Curated OER
Classifying Polygons
Learners study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Learners identify the properties of quadrilaterals.
Curated OER
Creating a "Concrete" Spreadsheet
Students create a spreadsheet that calculate the amount of concrete needed to pour various concrete forms.
