Math Hunt
Go on a scavenger hunt around your school to find evidence of math. Investigate different areas of your school for patterns, fractions, and different geometric shapes. Finally, create a spreadsheet and plot the data you've collected.
Alabama Learning Exchange
Abundant Area
Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...
San Francisco Symphony
Instrument and Visual Appreciation of Art
There are a lot of great ideas to be found here. To better understand the connection between art and history, learners research several music and art pieces, then relate them to major social events. They study the lives and works...
Mathematics Assessment Project
Floor Pattern
You'll never look at floor tiles the same again. An assessment task prompts learners to investigate relationships between patterns involving squares and kites to determine angle measurements. They then prove...
Curated OER
Tessellating Tiles
Second graders Make, name and describe, using their own language and the language of geometry, everyday shapes and objects. They create and talk about geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Tetrominoes Cover-Up
Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the lesson, they must...
Curated OER
Mosaics
Sixth graders discuss and identify shapes, spaces, colors, patterns, or tesserae in mosaics and compare them to cultural symbols of the Roman Empire. They design and create mosaics using paper.
Curated OER
Clay Tiles: Family Mosaics
Second graders design and create a clay tile to represent their families. They research and discuss similarities and differences among families of different cultures, create a tile to represent their own and then compile the tiles in a...

Sudoku: Sudoku Gameboard: Shapes
In this Sudoku worksheet, students cut out a set of tiles for use in a Sudoku game. Answers and a website reference for additional resources are included.
Curated OER
Tessellation Trial and Error
In this interactive lesson, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations. They...
Curated OER
Complexity Madness
After introducing the concept and formula for finding the area of a square, try this lesson. Fifth graders will use their prior knowledge to break apart various shapes in order to determine area. This lesson includes several examples,...
School Mathematics Project
Resource Sheets
This extensive and far-reaching collection of worksheets puts a new twist on many basic concepts. Learners use multiplication to trace a path from one point to another, tile a plane by converting between improper and proper fractions,...
Curated OER
Tessellations
For this tessellations worksheet, 10th graders solve 6 different types of tessellation problems that includes drawing. First, they define polygon, regular polygon, tessellation, regular tessellation, and semi-regular tessellation. Then,...

Backyard Building - Area and Perimeter
Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...
Curated OER
Minimum and Maximum Perimeter
Pupils practice a variety of strategies with varying numbers of tiles to form shapes and then find the minimum and maximum perimeter for each one. Each group is assigned a different area to build either with square tiles or a geoboard....
Curated OER
Egg-streme Tesselation
Sixth graders view a video of tessellating an egg shape. They focus upon the problem solving strategies used and how tessellation geometry was used to construct the three dimensional figure. They create their own tiling patterns.
