How to Give a Montessori Three Period Lesson for ages Three and Up

How to Give a Montessori Three Period Lesson for ages Three and Up

The Three Period Lesson is a way to present and introduce concepts and "new terminology," or the names of  things, to a child: new sounds (letters), numbers (symbols), geometric shapes, colors, and geography forms (like the land and water forms or the continents). It is also a way to enrich the child's vocabulary. The technique was originated by Edouard Sequin, a French educator from the nineteenth century.

There are three stages to the Three Period Lesson: the first stage, also called the first period, is the association or recognition of identity stage. It is an introduction of names and or concepts to the child. In the example lesson below, the names of three color tablets are introduced to the child: blue, red, and yellow. The names of the objects are introduced by the adult into the consciousness of the child: "This is red. This is blue. And this is yellow." In this first period, the child is making an association with the object and the name of that object.

In the second stage or period, called the recognition of contrasts stage, the names are repeated to the child who can now interact with the objects (in our example, the color tablets). In this second period, the child has an opportunity to demonstrate his new knowledge of the names or concepts that were just introduced to him by showing you (or holding up) the object when asked for it. The child is still given the names of the objects, but he has to show you which is the correct one by picking it up and handing it to you: "Can you give me the red tablet? Can you give me the yellow tablet? Can you give me the blue tablet?"

The third stage or period is the consolidation stage, the child is asked to name the color tablets all on his own, to pull from his mind and into consciousness, the names of the objects (or the colors of the color tablets as in our example). In this period, the child will show the adult whether or not he can identify the names of the new objects, concepts, letters, or numbers, as well as pronounce them correctly.

Few words are spoken during the Three Period Lesson, so as to better isolate the terms or names (blue, red, and yellow for example) that are being introduced and taught to the child.

It is important that the three objects chosen for a Three Period Lesson be contrasting, or different from each other. For example, presenting the letters "b" and "d" for the first time to a child would not be wise as they are so similar in shape; or the numbers six (6) and nine (9).

The Three Period Lesson can also be used by the adult to test the child's knowledge of the names of things (like colors, numbers, letters, animals, etc.) by asking the child, "What is this?" This is used a lot when teaching a child the letters of the alphabet or numbers. If, for example, you gave a three period lesson on the numbers "one," "two," and "three" on Monday, you would test the child on Tuesday to see if he remembered the names of the numbers. If he did not remember any of them, you would repeat the Three Period Lesson. If he remembered the "one," for example, but not the "two" or "three," you could either repeat the lesson on just the "two" and the "three," or introduce the number "four" and give a three period lesson on the "two," "three," and "four." If the child remembered the "one" and the "two," but not the "three," you could either give a lesson on the "two" and "three" or introduce the "four" and the "five" and give a lesson on the "three," "four," and the "five." It is sometimes best to give one familiar object along with two new objects in your three period lesson.

Three period lessons given to toddlers and young threes, or special needs children, are sometimes done with only two objects. Both objects can be new (unknown to the child) or one can be familiar and one can be new.

Materials: Small Number Rods (after the child knows how to put them in order from one to ten or one to five).

First Period:

1. Take the one, two, and three rods. Isolate them on the mat. Place one rod in front of the child. "This is one." (Touch your fingers on the red one rod as you say one.) "Would you like to count?" Child: "One."

2. Place the second rod in front of the child. "This is two: One, two." (Touch your fingers on the red as you say one and the blue as you say two, and count from left to right.) "Would you like to count?" Child: "One, two."

3. Place the third rod in front of the child. "This is three. One, two, three," (touching all three sections, one color at time). "Would you like to count?" Child: "One, two, three."

*Help the child to count the number rods with their open hand with palms down, touching each section, one color at time, from left to right, from red to blue.

Second Period:

1. Ask the child, "Give me the two please," child counts the number rods looking for the two rod, and hands you the two rod. "Thank you." Say to  the child, "Let's count it. One, two." (Remember to touch the colors as you count.)

2. "Give me the one please," child counts the number rods looking for the one rod, and hands you the one rod. "Thank you. Let's count it. One." (Remember to touch the colors as you count.)

3. "Give me three please," child counts the number rods looking for the three rod, and hands you the three rod. "Thank you. Let's count it. One, two, three." (Remember to touch the colors as you count.)

Third Period:

1. Hold up the two rod ask child "What is this?" Child says: "Two."

2. Hold up the one rod ask child "What is this?" Child says: "One."

3. Hold up the three rod ask child "What is this?" Child says: "Three."

You can go on to the next three rods (number four, five, and six) if the child is interested, or wait until the next day--but review the rods you introduced the day before.

Should You Refrain From Talking During a Lesson?

Hi Lisa!

I have read that during a Montessori presentation the teacher should not speak to not distract the child, and when the child is working the adult should not interrupt him. My question is: when and how is the language introduced? For example for cylinder blocks: thick and thin.

Thanks in advance,


After having a child with Down syndrome, who has severe language delays, I am not so strict about this issue of not talking to the child during a presentation. My son needed a lot of language! Repeated over and over!

I think there is a separate issue about interrupting a child when they are working on a material independently (and you are not giving them a lesson).

But when you are giving a lesson, language can always be included. If you are doing the knobbed cylinder block, for example, just point to the cylinder, touch it lightly and say "thick" then ask the child to touch it and repeat "thick." Do the same for "thin."

And let those concepts guide you through the day by pointing out thick and thin food or objects (thick banana, thin cracker for example).

Montessori Language & Outline for Ages 3 to 9

I am sharing my Montessori training lecture notes on language, an introduction and outline, for ages three to nine. The most important concept in early language development is that the child has to become aware that language and words are made of sounds. We achieve this with the help of the I Spy Game. The next step is to introduce the symbols that represent these sounds with the help of the Sandpaper Letters.

A Montessori Infant and Toddler Home Environment

I get a lot of questions about how to do Montessori at home with infants and their toddler siblings. So I created a Montessori Infant and Sibling Series. This is part one.
"How do I organize the work room areas (where all the Montessori-related materials are going to be) including a two-year-old area (such as art section, math section, etc.) and an 11-month-old area of the room?"
"What about their bedrooms and the living room? Which room should I start with first? It's just overwhelming."
"Should I make up a daily schedule first, or organize (plan, shop, and display) all the materials first? And how do I decide what I should put on the shelves for each of my children?"

DIY Bedtime Box With Day and Night Matching and Sorting: A Guest Post by Carolyn Wilhelm of Wise Owl Factory

I recently purchased Motherhood May Cause Drowsiness: Mom Stories from theTrenches, Lisa Nolan's mom lit parent humor anthology with forty contributing mom bloggers. Motherhood May Cause Drowsiness is very funny and poignant while describing the experiences of the sleep deprived mothers who contributed the chapters. Any young parents needing some comedic relief about their situations would feel less alone and more understood by reading this book. I've already sent it to a young mom who I know will enjoy the writing. The writers are all very talented and many have written other books and/or blogs. They are introduced at the end of the book with links for future reading and enjoyment.
I smiled for days remembering some of the lines in the book such as, "I hear a doggy barking!" spoken by a child trying to delay bedtime. The teacher mom I could so relate with, as both jobs can be exhausting. There are poems and stories, and it is the perfect bed stand book to help parent…
