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 collect data
using objects, pictures, and symbols. They organize data by sorting and
classifying in different ways. Students display data using multiple
In this unit, students become real
Students' number sense and problem
solving strategies are refined as groups compete for the title "Money
In this unit, students will use
geoboards to visualize the geometric meanings of square and square root.
Each geometric investigation in this
unit begins with an open-ended question that engages students in a study of
triangles and their properties. This lesson was adapted from "IDEAS"
by Marea W. Channel, which appeared in the November, 1993 Arithmetic Teacher
(Teaching Children Mathematics), Vol. 41, No. 3.
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.
These investigations use movement to
reinforce the concepts of linear functions and systems of equations. Multiple
representations are used throughout, along with tools such as motion detectors
and remote-controlled cars. Students explore how position, speed, and varying
motion are reflected in graphs, tables, and algebraic equations.
