Curated OER
Introduction to Fractals: Infinity, Self-Similarity and Recursion
Students think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is practiced.
Curated OER
Cartesian Coordinate System
Students explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.
Curated OER
Anamorphosis
Students classify optical illusions according to their distinguishing characteristics. They create anamorphic art and use Mylar flexible mirrors to view and then they describe and analyze the optical illusion.
Curated OER
Fractals Forever or Obvious and Hidden Order
High schoolers discuss ways computers use properties of similar figures to generate scale models and create scenes. they describe patterns they have seen on a fern, pineapple, or pinecone. Students research Benoit mandebrot, H. von Koch...
Curated OER
Perplexing Perimeters
In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...
Curated OER
Human Activity and the Environment
Students review and analyze graphs and tables as a group. They develop their graph and data analysis skills by converting data tables from Human Activity and the Environment into graphs.
Curated OER
Geometry and Shapes in the X-36
Students describe, draw, and classify shapes. They use the internet to research the X-36 aircraft. Students identify the geometric shapes in the aircraft. They calculate the number of sides in an x-36.
Curated OER
Using Coordinate Geometry by Land, Sea and Outer Space.
Students complete a table of values and plot points, as well as construct a graph on a coordinate grid. They construct two graphs on the same coordinate system, and identify the point of intersection. Students represent and record...
Curated OER
Understanding the Effects of Currency Exchangerates
Students examine the economic effects of a strong and weak U.S. dollar. They identify the currency used in countries which regularly trade with the U.S., discuss the pros and cons of a strong U.S. dollar, and calculate the prices in...
Curated OER
Petroglyphs and Pictographs
Fourth graders make necklaces out of petroglyphs that they stamp into clay. In this petroglyphs lesson plan, 4th graders draw designs and explain where they come from as well.
Curated OER
Incredible Edible Bridges
Students create a bridge using engineering and geometric concepts. In this geometry lesson, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem solving...
Curated OER
Slippery Slope
Students define patterns, relation and function. In this algebra lesson, students find the slope of a line and write equations of line. They model the slope using real life scenarios.
Curated OER
Optimization For Breakfast
Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.
Curated OER
Exponential and Exponents Functions
Students solve problems using exponential properties. In this algebra instructional activity, students differentiate between exponents, exponential and log functions. They graph their functions using table and exponents.
Curated OER
La Toteca- A Tropical Paradise
Students collect data on the time of the ferry. In this algebra instructional activity, students use the data to predict a ferry schedule. They also compute the depth where oxygen would be needed when diving.
Curated OER
Identifying Patterns
Students investigate the elements of a pattern. In this geometry lesson, students identify different shapes in a pattern and discover which shapes are missing in order to extend it. Students create their own patterns using...
