Graphs (2006)
When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a learning exercise that engages scholars to properly label line graphs. It then requests two applied reasoning answers.

Mixing Paints
Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...
Inside Mathematics
Magic Squares
Prompt scholars to complete a magic square using only variables. Then they can attempt to solve a numerical magic square using algebra.
Inside Mathematics
Snakes
Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Two Solutions
Many problems in life have more than one possible solution, and the same is true for advanced mathematics. Scholars solve seven problems that all have at least two solutions. Then three higher-level thinking questions challenge them to...
Noyce Foundation
Boxes
Teach your class to think outside the box. Scholars use the concept of equality to solve a problem in the assessment task. They determine how to use a scale to identify the one box out of a set of nine boxes that is heavier than the others.

Population
Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...
Curated OER
Platonic Solids
A chart in this activity prompts students to list the number of faces, vertices, and edges in each of five shapes. Additionally, students provide the number of faces that meet at each vertex as well as the number of sides of each face....
Curated OER
Ceva’s Theorem
Students prove and use Ceva's Theorem to solve problems. In this geometry lesson, students analyze polygons for patterns and calculate the area of each shape. They relate polygons to the real world.
Curated OER
Glide Reflections
In this glide reflection activity, students draw and answer questions about reflections of different shapes. Students answer 5 questions.
Curated OER
Robot Area
Students calculate the area of different polygons. In this geometry lesson plan, students explore polygons based in their shape and number of sides. They find the formula for the area and use each specific formula for each shape.
Curated OER
Exploring Properties of Rectangular Prisms
Learners explore the properties of rectangular prisms. For this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.
Curated OER
Triangular Prism
In this triangular prism worksheet, students cut out, fold and fasten the tabs to make a triangular prism model. This is a net pattern.
Curated OER
Pick's Theorem
Students investigate Pick's theorem by completing a lab. In this geometry lesson, students construct polygons using cabri software. They calculate the area of polygons and identify the vertices of each shape.
Curated OER
Exploring Secants: Products of Segments
Learners explore secants and circles. In this geometry lesson, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.
Curated OER
Grandfather Tang's Story
Third graders read the story Grandfather Tang's Story and then make their own tangrams based on the story. In this tangrams lesson plan, 3rd graders make patterns with their tangrams and follow directions their teacher...
Fun Stuff To Do
Square Pyramid
Your geometry learners will appreciate this net for a square pyramid. Copy, cut, and manipulate to explore the surface area or volume of a square pyramid.
Curated OER
Compare Fractions
In this comparing fractions practice worksheet, students sharpen their problem solving skills as they solve 6 story problems that require them to compare fractions.
Curated OER
Block It: Using a Manipulative to Solve Math Problems
Students practice using visuals to solve math problems. In this math manipulative lesson, students utilize pattern blocks to participate in a class game in which geometric shapes touch other player's pieces. Students gain points based on...
Curated OER
Tessellmaniacs
Seventh graders create 3 original tessellation using polygons. They slide, turn, rotate and glide their designs on the computer. They print their tessellation on a T-shirt and teach the 6th graders about tessellations.
