Sandpaper Numbers (buy here) is a lesson that is in a math area but is a mixture between the Sensorial area in Montessori classroom and math. Sandpaper numbers are very easy to make at home: all you need is sandpaper, trace numbers, cut them out and glue on a cardstock.
The purpose of this lesson is for the child to learn the symbol/numeral that represents the number. And what makes this traditional Montessori lesson so special is that the child learns with so many different senses: 🖐️ touch, 👁️sight, 👂hearing, learning the name. First, the child 👁️ visually sees the number, the child also develops his/her tactile senses by tracing it: that is feeling it sensorial with touch, and finally, the child learns the name of the symbol of the number.
To introduce the sandpaper numbers to the child, you would start with three numbers at a time (with smaller children you may want to start with just numbers one and two), and you will present a 3🅿️🌠 Three Period Lesson. (For details on Montessori 3🅿️🌠 Three Period Lesson, see a post here.)
How to present a 3️⃣🅿️🌠Three-Period Lesson: (start with 3 numbers at a time, e.g presenting numbers 1-3):
🔹Period 1: choose a number and while tracing that number say: “This says 1. Would you trace 1?"; "This says 2" ... etc
🔹Period 2: "Will you show me 1…2…3 ”?
🔹Period 3: “What is this?"
This lesson can last a while: start with numbers one and two, and then start adding more numbers as the child gains confidence. If the child loses an interest, simply put away the lesson and come back a few days later.
Math can be mundane and tedious, so to make an activity fun, I came up with these few extensions that add a "play-and-learn" dimension to the activity.
Silly Numbers Game:
While keeping the numbers visible, add some fun by giving simple directions: put three on your head, turn two upsides down, hide one behind your back etc. This game was a big hit when Adrian was about 2 years of age: he thought the directions were hilarious!
Another Extension is the game called: Crazy Mixed Up Numbers:
Take sandpaper numbers one through ten (or just start with one through three) turn numbers upside down and rearrange, mixing them up. Then, invite your child to knock:
"Knock-Knock – who is there? What is this number?”
Once the child turns over the number, invite him/her to name the particular number (resembling of a 3rd Period Lesson). This activity can be modified for older children as well, using larger numbers, like 100, 200, 300 etc.
I think if you make learning fun, engaging and hands-on, your child will keep coming back to the lesson: learning effortlessly, with grace, and most importantly, caring on the love of learning.
DIY Sandpaper Numbers:
What you will need:
- green cardstock to resemble the traditional Montessori Sandpaper Numbers
- sandpaper from your local hardware store,
- scissors (children are also using a paper cutter for more precision)
- and glue.
Having your child make or help you make these DIY Sandpaper NUmbers will only ignite the excitement, promoting interest and engagement.
By sensorially feeling the number, the child is able to perceive the symbol through senses other than just visual.
