    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.
