Great Extensions

Creative, Open-Ended Materials to Enrich the Montessori Environment

Great Extensions grew from a child's love for stamping. Our custom designed stamps will enhance your existing Montessori lessons. We offer stamps for the golden bead materials, understanding place value, short and long chains, mathematical operations (addition, subtraction, multiplication, and division), parts of speech, and sentence analysis. All of our stamps are designed to be used as an extension material in the Montessori environment. Once a lesson is mastered, the stamps are used to produce a record of accomplishment. When using the stamps, markers are the recommended ink source. The use of markers allows the child to develop refinement of movement, to have versatility in color choice, and to take responsibility in the care and appearance of the materials.
Color-Mixing and Activity Game Board
The Color Mixing Activity consists of a template and an acrylic disc. Children place drops of colored water as indicated by the template directly onto the acrylic disc. After all the drops are in place, the child mixes each cluster. The drops in each cluster are sequenced to create the colors of the color wheel once completed.
Quilted Mats
All of our mats are machine washable and have ribbons on the back which allow the mats to be folded, rolled and then tied for space economy and easy placement on trays or shelves.
THE ART OF CREATING TEACHER-MADE MATERIALS: This extensive manual takes you through the steps required in creating beautiful classroom materials from idea conception through finished product. Includes over forty full-color illustrations.

Great Extensions grew out of a teacher’s desire to bring open-ended, quality materials to the Montessori classroom that would enhance and support the classic Montessori materials. Started in 1994 with only a few items to offer, Great Extensions materials are now found in classrooms world wide.

Every item offered by Great Extensions is first tested in the classroom to ensure its popularity with the children, durability and versatility. Each item is designed to compliment the Montessori materials and encourage repetition and a passage to abstraction. Above all, the materials are inviting to the children and add a strong point of interest to the lessons they are designed for.

With the guidance of nationally-known Montessori guide Lori Karmazin, Great Extensions will continue to provide quality Montessori Materials that enhance and enrich the learning experience of children all around the globe. It is our goal to continue to improve our products while developing more materials that aid in giving children the world over the benefits of the Montessori Experience.
