As with many curricular areas, geometry in Montessori is kind of totally different than it’s in conventional training. Virtually all the examine is hands-on, utilizing picket shapes and nomenclature playing cards to show geometric ideas.
This is essential in the case of geometry, as analysis exhibits that it takes kids a very long time to have the ability to image shapes accurately of their minds, and even longer to have the ability to mentally “rotate” them. Working with them in a hands-on method helps immensely.
Where Did Geometry Come From?
Geometry is likely one of the oldest research in human existence. The beginnings of geometry may be traced again to historical Egypt, from round 3000 BC. (You would possibly wish to take a look at my Story of Geometry for a neat strategy to inform youngsters about these historical beginnings). Since geo means “earth” and metria means “measure”, early geometry was all about measuring the earth to find out boundaries of possession.
Geometry was initially a really practical science (as opposed to theoretical), involving measurements, areas, and quantity. Vital early discoveries embrace formulation for figuring out lengths, areas, and volumes; circumference and space of a circle; space of a triangle; quantity of a cylinder, sphere, and pyramid. Shortly, geometry started to be utilized to many different disciplines, most notably astronomy. The intersection of astronomy and geometry enabled scientists to find out the position and motion of stars and planets.
Geometry via the Senses
In Montessori, we begin working with shapes and patterns early. The Sensorial space of the 3-6 classroom is basically the examine of geometry; in elementary, this space turns into geometry. Early geometry supplies embrace the triangle packing containers, the geometric cupboard, and the geometric bases and solids. We name these early research “Exploration of Kinds”. (Due to Alison’s Montessori for the geometric cupboard image!)
In these early actions, kids are merely learning the names of shapes and starting to affiliate the identify with the form. In true Montessori style, the early geometry actions additionally improve hand/eye coordination and nice motor expertise because the baby traces the define of the form with a fingertip or pencil.
Naming & Knowing
After the kid has explored types and shapes, they’re invited to know figures and their particulars. These are the nomenclature playing cards (or geometry folders) that comprise a lot of the 6-9 geometry curriculum. (See image: Sorts of Angle Pairs). Extra supplies embrace the geometry stick field and command playing cards. Now, the kid is studying the totally different components and sorts of traces, angles, triangles, and different shapes.
The distinction between 3-6 and 6-9, as in any curricular space, is that this: the kid in 6-9 is discovering the properties of no matter it’s they explored sensorially in 3-6. The kid begins to know easy definitions and specific ideas in their very own phrases. Apart from the ready-made geometry supplies (each picket and printed), I discover it useful to maintain small picket sticks (discovered at craft shops) and string out there within the geometry space for freeform exploration.
The Golden Elements of Geometry
In 9-12, the kid is launched to 3 nice ideas of geometry: congruence, similarity, and equivalence. These ideas are known as the “Golden Components” of geometry. The dynamic side of this degree contains taking figures aside, shifting them about, after which placing them again collectively in such a manner that they present equivalency to a different determine. For instance, a baby would possibly reconfigure a triangle to point out that it’s equal to a specific rectangle.
The nomenclature playing cards at this degree embrace the Golden Components in addition to terminology for figures, together with such phrases as peak, width, and base, space, and quantity. Kids at this level may even take pleasure in researching and learning about well-known names from geometry, together with Pythagoras, Euclid, and Archimedes. I’m an enormous fan of utilizing books to show these kinds of ideas; you’ll discover just a few geometry titles listed here underneath the 9-12 age group.
Measuring Our Earth
Geometry must be enjoyable! Shapes are throughout us, and we use the ideas of geometry day-after-day with out realizing it. By introducing kids to geometry step-by-step, we insure their agency grasp of ideas in addition to enjoyment of the exploration that comes naturally after we measure the earth and the whole lot in it.
Notice: the Complete Lists embrace a piece for geometry, itemizing all of the supplies and ideas for geometry in every age group. Very useful!
