Chelsea Cutting from Mount Gambier, South Australia, tells us about the
real-world connections her students are able to make after using
Illumination resources.
Success Story
Jan Gebert is an Illuminations lesson plan reviewer and instructor of
professional and secondary education at East Stroudsburg University. So
she definitely knows a thing or two about quality lessons. Illuminations
asked her for her favorite out of our 600+ lessons.
Success Story
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?"
Success Story
In this unit, students will use
geoboards to visualize the geometric meanings of square and square root.
Math
Content
Students will:
- Connect the square of a number to the area of a square
whose side length is given.
- Understand that the square root of a number can be
represented as the side length of a square whose area is given.
- be introduced to irrational numbers as the side lengths
of non-traditional squares. Make connections between geometry, measurement
and number sense through the use of manipulatives.
In this unit, students learn the Law of
Sines and the Law of Cosines and determine when each can be used to find
a side length or angle of a triangle.
The concepts of greater than, less than, and equal to
are explored in this 2-lesson unit. Students create piles of food on
two islands, and their fish always swims toward the island with more
food. The fish's mouth is open to represent the greater than and less
than symbols. Students transition from the concrete representation of
using piles of food and the fish to writing inequalities with numerals
and symbols.
Many students may have seen Pick’s
Theorem in middle school. In this set of lessons, students rediscover the
theorem, use algebra to determine the coefficients of the equation, and explore
the concept of change as a mechanism for finding the coefficients of Pick’s
Theorem. Math
Content
Students will:
- Solve systems of equations.
- Find rates of change.
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 begin an exploration of cryptology by first learning about two
simple coding methods— the Caesar cipher and the Vigenere cipher.
Students then use matrices and their inverses to create more
sophisticated codes.
Use remote-controlled cars to create a system of equations.

Puzzles
provide excellent opportunities for students to apply spatial
relationships in an entertaining and meaningful way. In the first part
of this lesson, the students use concrete materials to develop the
skills needed to work with interactive Tangram puzzles in the second
part of the lesson. The students also further develop their
understanding of spatial relationships and develop problem-solving
skills.
