Deeanna Golden, a teacher of 24 years at F.M. Golson Elementary
School in Marianna, Florida, is a beloved Illuminations lesson plan
writer. So we asked her, "Why do you think it is important to share resources?"
In this unit, students use the area formula
for a rectangle to discover the area formulas for triangles,
parallelograms, and trapezoids. Students also consider irregular figures
whose areas can be determined by estimation or decomposition.
In this unit, students explore circles. In
the first lesson students apply the concepts of area and circumference
to explore arrangements for soda cans that lead to a more efficient
package. In the second lesson, students experiment with three-dimensional arrangements to
discover the effect of gravity on the arrangement of soda cans. The final lesson allows students to examine the more
advanced mathematical concept of curvature.
Although no single lesson in this
unit addresses connections and representation by itself, the entire unit
focuses on the Connections and Representation Standards by allowing students to
make connections among mathematical ideas and asking students to use various
representations to organize their work.
Students will explore theoretical
and experimental probability and the relationship between them. Students will
also graph an experiment to further explore the relationship according to the
Law of Large Numbers.
In this unit, students practice
measurement by measuring themselves. Students use nonstandard units to practice
measuring their heights and arm spans. Then, they create a "body map"
and use directional and positional words.
In this unit, students collect data
using objects, pictures, and symbols. They organize data by sorting and
classifying in different ways. Students display data using multiple
Construct perpendicular bisectors, find circumcenters, calculate area, and use proportions to solve a real world problem.
