Sensorial – Part 4

January 21, 2015/in Blog, Uncategorized /by access

Today we continue our exploration of the Sensorial area of the Montessori classroom, specifically discussing the following materials – the color blocks, the ten geometric three-dimensional shapes, touch boards, and the sound cylinders . Sensorial is an area of the Primary classroom that is uniquely “Montessori.” Many of the jobs hearken directly back to Dr. Montessori when she set up her original classroom for the benefit of the young, unattended children in the housing projects of Rome in the early 1900’s.

There are three color boxes. The first has the three primary colors (red, blue, and yellow). The second has 12 different colors. The third box has nine colors, but in different grades from light to dark.

Ten Geometric three-dimensional shapes made from wood and usually painted blue. The shapes are:

Sphere
Cone
Ovoid
Ellipsoid
Triangle-based pyramid
Square-based pyramid
Cube
Cylinder
Rectangular prism
Triangular prism

Touch boards groom the student’s sense of touch and enhances their ability to distinguish between the smooth and rough.

Sound cylinders are sensitizing the child to the gradations of sound from soft to loud and at the same time, teaching the child how to match the sounds from the red box with the exact same sound in the blue box.

Once the basic sensorial lessons are mastered, numerous extensions can be practiced with each of the materials. Often sensorial materials will engage the interest of the child for long periods of time because the materials are concrete and the “control of error” is so immediate. There are also many math and language applications using the sensorial materials, such as labeling the materials, or taking a moment to count the quantity of materials used in a particular job. Sensorial is part of the classroom that uses all five senses and draws directly from the wisdom of Dr. Montessori in a concrete, useful and vivid way.

Sensorial – Part 3

Today we continue our exploration of the Sensorial area of the Montessori classroom, specifically discussing the following materials – the binomial, trinomial cubes, and the constructive triangles . Sensorial is an area of the Primary classroom that is uniquely “Montessori.” Many of the jobs hearken directly back to Dr. Montessori when she set up her original classroom for the benefit of the young, unattended children in the housing projects of Rome in the early 1900’s.

The binomial and trinomial cubes are more advanced works that not only teach specific pattern matching prisms together, there is an underlying algebraic equation that can be explored Lower Elementary classes.

The constructive triangles are put together to form various shapes. Shapes made with the triangles include the parallelogram, hexagon, rhombus, and trapezoid.

Join us on Wednesday as wrap up our series on Sensorial.

Sensorial – Part 2

Today we continue our exploration of the Sensorial area of the Montessori classroom, specifically discussing the following materials – the red rods, cylinder blocks, and the knobless cylinders . Sensorial is an area of the Primary classroom that is uniquely “Montessori.” Many of the jobs hearken directly back to Dr. Montessori when she set up her original classroom for the benefit of the young, unattended children in the housing projects of Rome in the early 1900’s.

Another set of ten pieces is the red rods. “The red rods are rods of equal diameter, varying only in length. The smallest is 10 cm long and the largest is one meter long. Each rod is 1 square inch thick. By holding the ends of the rods with two hands, the material is designed to give the child a sense of short and long.”

Here is an example of more advance extensions of using the brown stairs, the red rods and the knobless cylinders:

“The cylinder blocks are ten wooden cylinders of various dimensions that can be removed from a fitted container block using a knobbed handle. To remove the cylinders, the child is taught to use the same three-finger grip used to hold pencils. Several activities can be done with the cylinder blocks. The main activity involves removing the cylinders from the block and finding the right hole to replace the cylinder in. Small, tall and short, thick and thin, are the concepts being conveyed to the children as they handle the cylinder blocks.”

Also called the knobless cylinders, the colored cylinders are exactly the same dimensions as the cylinder blocks mentioned above.

There are 4 boxes of cylinders:

Yellow cylinders that vary in height and width. The shortest cylinder is the thinnest and the tallest cylinder is the thickest.
Red cylinders that are the same height, but vary in width.
Blue cylinders that have the same width, but vary in height.
Green cylinders that vary in height and width. The shortest cylinder is the thickest and the tallest cylinder is the thinnest.

The child can do a variety of exercises with these materials, including matching them with the cylinder bloc

ks, stacking them on top of each other to form a tower, and arranging them in size or different patterns.

Here, the knobless cylinders are used with the cylinders from the cylinder block.

Below, a student has combined the knobless cylinders and the pink tower, ordering the materials in sequence from the biggest to the smallest.

Practical Life – Part 2

January 8, 2015/in Blog /by access

Today we continue our series exploring the Practical Life area of the Montessori classroom, focusing in this post on the ways in which Practical Life skills benefit other curriculum areas.

Many of the exercises in the Practical Life area are preparation exercises of Sensorial works. The exercises help to fine tune the development of the child’s senses. Many uses of the five senses occur in the Practical Life area: sound, sight, and touch are used in equipment-bases activities, such as bean scooping; smelling and tasting are involved in the preparation of food.

Practical Life not only develops the child’s senses and teaches real life skills, but sets the basic foundation for other areas to come. For example, understanding size, weight, and equal distribution are skills which are vital when the child is introduced to the Math area of the classroom.

Perhaps the most significant is the development of the pincer grip, which allows the child to correctly grip a pencil and begin working in the Language area.

Sensorial – Part 1

January 7, 2015/in Blog, Uncategorized /by access

Sensorial is an area of the Primary classroom that is uniquely “Montessori.” Many of the jobs hearken directly back to Dr. Montessori when she set up her original classroom for the benefit of the young, unattended children in the housing projects of Rome in the early 1900’s. Dr. Montessori could see the advantage of having children develop and refine their five senses. She also understood that if a child was presented with materials where they could check their work themselves, and know visually that the job was done correctly or incorrectly due to the precise way the materials were used, then their level of independence and self-confidence would increase. Dr. Montessori referred to this concept as the “control of error’’ and it has great significance throughout the classroom, and especially in the sensorial area.

As the child begins to explore the sensorial works, one of the first jobs introduced is called the pink tower. “The pink tower has ten pinkcubes of different sizes, from 1 centimeter up to 10 cm in increments of 1 cm. The work is designed to provide the child with a concept of small and big.” The child starts with the largest cube and puts the second-largest cube on top of it. This continues until all ten cubes are stacked on top of each other. The control of error is visual. The child sees the cubes are in the wrong order and the tower becomes unstable if a larger cube is placed on top of a smaller cube.

Many of the sensorial materials are made with 10 components so that the students get used to counting 1-10 quite naturally.

For instance, the brown stairs is made up of 10 sets of wooden prisms and introduces the concept of thin to thick. “Each stair is 20 cm in length and varies in thickness from 1 to 10 cm. When put together from thickest to thinnest, they make an even staircase.” After the initial pink tower and brown stair lessons are mastered, both materials can be used together forming interesting combinations.

Join us next week as we continue looking at the Sensorial part of a Montessori classroom.
