Curated OER
States Research Project
Eighth graders create an in-depth research report on a state. They conduct Internet research, write a comparison essay about New York State and their assigned state, create a 3-dimensional map, and develop a Powerpoint presentation.

Papermaking
Imagine recycling food scraps and using them to make paper. The directions are all here in a seven-page packet that details several paper-making strategies.
Curated OER
AZTEC TILES
Pupils observe the shapes and lines that make up Aztec sculpture, study Pre-Columbian art as they discover the Aztecs, Mayans and Incas. They create a small-scale Aztec tile using pasta. Creative, clever and engaging.
Curated OER
El Misterio del los Mayas (The Mystery of the Mayas)
Students, working in groups, research different aspects of the Mayan society of the classical period. They study the rise and fall of the civilization and present the information in multimedia presentations.
Curated OER
NUMB3RS Activity: Chains and Pyramids
Watch an episode of the TV show, NUMB3RS and then explore the mathematics of chain letters and pyramid schemes, both of which involve geometric progressions and exponential growth. They discuss why both are dangerous and illegal.

Paper Flowers
Here is a great art project to use at the onset of spring. Little ones use paper towels, tempera paint, and glue to create free-form flowers. Tip: Use this idea to make the front of a Mother's Day card.
Curated OER
Tissue Paper Dye Painting
Use tissue paper squares to create collage art. Young artists discuss colors as they place and glue each piece of tissue on the paper. Tip: Cut out large basic shapes instead. Have the class create images using the tissue shapes (robots...
Curated OER
Rate of Change
Young scholars observe and calculate slopes. In this algebra lesson, students graph equations and determine the pace at which the slope is changing. They use the navigator to see the change as they graph the lines around.
Curated OER
Corresponding Parts of Congruent Triangles
Students identify different parts of a triangle. In this geometry lesson, students differentiate between similar and congruent triangles. They use the navigator to crate a visual of the different parts of a triangle.
Curated OER
Triangle Sum Theorem
Teach your class how to solve problems using the triangle sum theorem. In this geometry lesson plan, young scholars identify the missing angles in a triangle using the sum theorem. They graph triangles on the TI and moves the sides...
Curated OER
Scale Factor Area Perimeter
Mathematicians compare triangles at different scales. In this geometry instructional activity, learners calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles...
Curated OER
Pythagorean Triples
Teach how to solve problems with right triangles. Students use the Pythagorean Theorem to identify missing sides and angles. Then, they will define and use the Pythagorean Triples to solve problems.
Curated OER
Creating a Midpoint Quad
Using a TI Navigator to drag quadrilaterals around to create different shapes, students learn how to draw midpoints in their quadrilaterals. In this geometry lesson, students solve problems using the properties of quadrilaterals.
Curated OER
Exploring Diameter and Circumference
Learn how to identify the diameter and circumference of a circle. Then, collect data on a circle and relate it to the diameter and circumference of a circle. Last, plot data and find the line of best fit.
Curated OER
Tessellations with Regular Polygons
Show your learners how to create tessellations using different polygons. This is achieved by having students make observations of polygons to find the ones that will tessellate.
Curated OER
Glide Reflections
Perform reflections and transformations by having your students create glide reflections from translated shapes. They use the TiNavigator to explore transformations.
Curated OER
Triangle Midsegment
Learn how to calculate the length and midsegments of triangles. Students differentiate between similar and congruent triangles. They create a spreadsheet with their findings.
Curated OER
Creating Parallel Lines and Transversals
Have your class create parallel lines. Students will learn how to identify the different angles created by a parallel line cut by a transversal. Then, they identify and name similar and different angles.
Curated OER
Create a Playbill!
Students examine the variety of elements for a written play and create a playbill. They read about and define literary elements on a worksheet, and participate in a dramatic reading. Each student then creates and publishes a playbill.
