National Pi(e) Day March 14
“Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.” -www.piday.org/
Grant Wood AEA Media Center materials that can support your Pi Day celebrations:
- "Math Skills Sharpeners, Grade 6" by Ellen Jo Moore - Contains ten units that provide practice for the following mathematical skills: computing with multi-digit whole numbers, solving two-step equations, multiplying and dividing decimals to the thousandths, calculating the circumference of a circle, elapsed time and area and perimeter, constructing and interpreting graphs, greatest common factor and least common multiple, converting customary measure to metric measure, and plotting ordered pairs on a coordinate graph. Each unit ends with an assessment page.
- "Why Pi?" By Johnny Ball - A collection of activities that explore practical math applications from throughout history.
- "Activity Math (4-6): Using Manipulatives in the Classroom" by Anne M. Bloomer - Activity math is a complete sourcebook of replacement lessons - a dictionary of ideas for using manipulative activities to teach specific skills. Lessons are organized into eleven math strands: number skills, place value, addition, subtraction, multiplication, division, fractions, decimals, ratio and percent, geometry, and measurement.
- "Designer Digs: Finding Area and Surface Area" by Renata Brunner-Jass - The mathematical concepts of perimeter, area, and surface area are explored as a student designs dream rooms for a school project. Readers learn the formulas to calculate area for quadrilaterals and triangles. Additional concepts include parallel lines, right angles, irregular polygons, decomposing shapes, and area nets. This book features a discover activity, history connection, and mathematical vocabulary introduction.
- "Geometry Station Activities for Common Core Standards" - Contains 18 sets of activities that focus on congruence, similarity, right triangles, trigonometry, circles and expressing geometric properties with equations. Each set has four different stations where students work in small groups moving among the stations. Activities are correlated to the common core state standards for mathematics.
- "CA Geometry: Area, Circumference, Volume" - Streaming video through media catalog from Khan Academy
- "Radius and Diameter From Circumference" - Streaming video through media catalog from Khan Academy
- "Area of a Circle" - Streaming video through media catalog from Khan Academy
Lisa O’Brien, Vinton-Shellsburg High School teacher, said “The VSHS math department celebrates by having students create over 350 digits to represent numbers for Pi Day. A time-lapse video is created to show off students work throughout the school." Students at VSHS also celebrate Pi Day by baking their favorite Pi(e) and sharing with their classmates.
