    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
    The 23-year teacher modifies games to meet the different learning needs in her classroom. See how she modified Deep Sea Duel.
    Success Story
    Diana Flores, who has a self-contained classroom, teaches highly and profoundly gifted students in Phoenix, AZ. Flores says math "rotations" is a "big-kid way to say centers." One of these math stations hosts computers, which students use frequently to visit Calculation NationTM .
    Success Story
    Much like athletes must warm up their muscles before heading into a game, students often warm up with engaging classroom activities or problems of the day before diving into the daily math lesson. Wan Chow of Bishop Strachtan School in Toronto finds the perfect warm-up in Illuminations.
    Success Story
    Francisco Santiago works as a youth counselor for York County in Pennsylvania. Committed to helping residents prepare for successful futures, he came to Illuminations seeking out resources for motivation and remediation of mathematics.
    Success Story
    Pamela Olmstead has been a middle school math and science teacher for 15 years at Chehalis Middle School (Chehalis, WA). One lesson that she has referred to all year long is Balancing Shapes, which uses the online applet Pan Balance—Shapes.
    Success Story
    Teachers are not the only ones who encourage students to play Calculation Nation--parents do too! Dana Slevin, and her middle school daughters play Calculation Nation at home.
    Success Story
    Matthew Jaques, ninth and tenth grade teacher for Cathedral High School in Springfield, Massachusetts, discovered Illuminations by way of Bright Ideas and has been using, modifying and creating his own lessons ever since.
    Success Story
    Losing weight is a popular New Year’s resolution. Some people turn to exercise to help them achieve this goal, but one teacher wonders if it’s possible to keep this resolution while following a diet of fast food.
    Success Story
    Terry Johanson, learning support facilitator for Prairie Spirit School Division, and Kirsten Dyck, physics teacher at Saskatchewan High School, worked together to team plan and teach an Illuminations lesson.
    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.

     

    Lesson Plan

    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.

     

    Lesson Plan
    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.
    Lesson Plan

    In this interactive geometry investigation, students explore polyhedra using different representations and perspectives for three dimensional block figures. In addition, students will examine area and volume concepts for block figures within this context.

    Math Content

    Students will:
    • Analyze characteristics and properties of three dimensional geometric shapes and develop mathematical arguments about geometric relationships.
    • Use visualization, spatial reasoning, and geometric modeling to solve problems.
    • Create three dimensional shapes using the isometric drawing tool and represent these shapes as isometric drawings.
    • Find the surface area and volume of various polyhedra created in this unit.

    If possible, each student should have access to an individual computer.

    Lesson Plan
    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.
    Lesson Plan
    Wendy Cleaves is a Mathematics Coordinator at the Regional Science Resource Center at UMass Medical School in Shrewsbury, MA. At the center, Cleaves supports pre-K-12 STEM educators by providing a professional development institute entitled, "Increasing Accessibility to Algebra & Geometry for ALL Students."
    Success Story
    It has often been said that love happens when you least expect it, and now the same can be said for finding math resources. Victoria Miles, 7th grade math teacher at Abigail Adams Middle School, came upon Illuminations after a Google search directed her to the site.
    Success Story

    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 representations.
