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 the following lessons, students
participate in activities in which they focus on connections between
mathematics and children’s literature. Three pieces of literature are
used to teach geometry and measurement topics in the mathematics
curriculum, from using and describing geometric figures to estimating
volume of figures.
These lessons were adapted from "Ideas: Mathematics
and Children’s Literature," by Martha H. (Marty) Hopkins, which appeared
in The Arithmetic Teacher, May 1993, pp. 512‑519.
By yourself or against a friend, match whole numbers, shapes,
fractions, or multiplication facts to equivalent representations.

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.
