More No-Three-In-A-Line
Fourth graders read Mary's problem and make sure that they examine it.
After some discussion, let the class work on the problem in their groups.
They then take turns in putting a picture of their arrangement on the board.
Curated OER
Manipulative Mania
Students explore tangram vocabulary and tangram designs, creating an art design that contains various geometric parts. They complete a checklist titled, Important Thing About a Quilt Design.
Curated OER
Flying Geese
Students examine the Flying Geese quilt pattern, and discuss and identify the pattern. They write a paragraph titled, My Quilt Report, summarizing the information discussed about the quilt patterns.

Students explore the processes involved in decorating eggs. The story, "Rechenka's Eggs" or "Chicken Sunday" by Patricia Polacco forms the introduction to the research.
Curated OER
Tessellations
Fifth graders investigate the relationship between math and art by examining patterns and polygons.They examine how polygons make up the patterns that form tessellations, and determine tessellations that occur in nature. Finally, they...
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
Curated OER
Calculus: Graphical, Numerical, Algebraic
Students explore the interplay between the geometric and analytic information and on the use of calculus both to predict and to explain the observed local and global behavior of a function. They write a paragraph describing any...
Curated OER
Absolute Value of Linear Functions
Students discover how abolute value affects linear functions. They complete a worksheet simulating a path for miniature golf hole in one for three figures. They construct a hole in one graph for each hole marking the X and Y coordinates.
Curated OER
Fractional Blocks
Young scholars explore the concept that fractions can also be considered a ratio. They discover that the fraction bar can be read as "out of." Students practice basic multiplication facts and use patterns to find fractions of shapes.
