Knobless cylinders is four sets of ten cylinders in each set, varying in height and/or diameter. Each set is in a separate wood box with a lid painted the same color as the cylinders: red, green, yellow and blue. Yellow cylinders vary in height and diameter. Green cylinders vary in height and diameter. Red cylinders vary in diameter only (height remains constant). Blue cylinders vary in height (thickness/the diameter is the same).
The purpose of these cylinders is to develop child’s fine-motor movements, concentration, hand-eye coordination, and visual perception of dimension. The material also provides experiences of seriation and gives the child basic language important in maths.
The control of error: (a) visual ~ the child can discern irregularities in the seriation (can be checked by running a finger on top of cylinders), or (b) physical: if the tower topples.
Age: 2 ½ – 3 years approx. I love this material since there are so many extensions, numerous pattern options, sequence cards (see below) which vary in the degree of difficulty, so your child even beyond three years of age can still enjoy these cylinders.
Presentation: For example, selecting the yellow box. Show the child how to carry the box using two hands cupped around the box. Remove the cylinders one by one grasping them over the top with your dominant hand, using the pincer grip. Show the child how to grade the cylinders from biggest to smallest in a horizontal line. Then, invite the child to grade the cylinders.
Alternatively, you can invite the child to build a standing tower with the cylinders starting with the largest cylinders first. (If the activity is not done on a table, you may use the lid of the box as a base.)
Lastly, the child can use more than one set of cylinders together to discover different properties such as similarities and differences in dimensions between the cylinders. This is where you would use sequence, pattern and comparison cards. I purchased these cards from Montessori Print Shop, and you may download them for your personal use only as outlined below. They are arranged in a progressive order of difficulty:
Set 1 Knobless Cylinder Sequence Cards
Set 2 Pattern Cards
Set 3 Pattern Cards
Set 4 Knobless Cylinder Comparison Cards
Below are patterns Adrian did starting at 2 ½ years of age. (Please, note, that simple seriation can be introduced as early as two years of age.)
Below, Adrian at 36 months, is using the 4th Set Knobless Cylinder Comparison Cards:
When combining more than one set, the child should sort the sets individually first.
The child can self-check by running a finger across the cylinders to confirm seriation.
Below are Extensions Adrian had done at 4 years old (11/3/2017).
Generally, you would start introducing sensorial activities to a toddler at about two years of age in the following order:
(1) Knobbed Cylinders, (2) Pink Tower, (3) Brown Stairs, (4) Color Tablets, followed by
(5) Knobless Cylinders.

“You can make almost anything out of 📦 cardboard” - said Adrian so here we are: an improved 🧮👌🏻 .
💡 The earlier you start introducing your little one to numerals and quantities, the more success they will have later on in their academic lives. We “officially” started a Montessori Math curriculum with Adrian when he was two years old! I am a strong believer that I would rather be early than late. If the material is introduced too early, a child would simply show no interest and you, as an educator, would simply come back to it later. On the other hand, if the material is introduced too late, the sensitive window of opportunity is closed forever and the chance for a seemingness, natural and effortless absorption of information is now gone! .
Remember, repetition is the key to mastery.

. 📦🧮 Punch Points :
1. a NUMERAL is a written symbol we, humans, decided to represent a particular quantity (written in black). 2. COUNTERS, also called manipulative, [here pony beads] help children build counting and subitizing abilities while expanding spatial awareness.
3. LEARN ADDENDS of each numeral 2-10!! If children memorize which combinations make each number, they will ace any math problem in a future.⚠️I purposely broke each number into its addends, well, most common combinations such as 5+5=10; 6+4=10 and so forth. .
💡 GOAL: to master SUBITIZING: which is the ability to instantly recognize without counting the number of objects present in a small group. So with practice, you child should instantly tell you what 6 is made of without counting actual beads! .
