🖐️Sandpaper 🔢 Numbers (Early Montessori Math)

In a Montessori Math curriculum, after introducing Numerical Rods (buy here) at around two years of age, Sandpaper Numbers (buy here) are generally introduced next, where a child visually sees the number; then traces it, feeling it sensorially with a touch; and finally, learns the name of the symbol of the number. Sandpaper numbers is a sort of a mixture between a sensorial and a math activity since the child learns the symbol/numeral which represents the number with different senses such as touch, sight, and hearing, while learning the name of a number.

The best way to present sandpaper numbers is using a 3🅿️🌠Three Period Lesson: (for a detailed 3🅿️🌠 Lesson presentation, see a post here). Start with three numbers at a time, for example presenting numbers one through three: 

In a Nutshell: (1P) This says ______.            (2P) Will you show me ______?         (3P) What is this?  

  • (1st P) Choose a number and while tracing that number with an index and third finger say: “This says 1. Would you please trace 1?";  "This says 2." … etc. (You would emphasize on "says vs. is" because the written number is merely a symbol representing that numeral and not the actual quantity.)
  • (2nd P)  “Will you show me 1?… 2? … 3?"
  • (3rd P) What is this?" 


At 31 months, Adrian can complete the 3🅿️🌠 Lesson only with numbers one through three, showing and naming them correctly when asked even during the last Third Period: "What is this?" However, starting with a number four, he confuses to name the numbers correctly (the Third Period). 

p.s. An update: by 34 months, Adrian could correctly complete the entire 3🅿️🌠 Period Lesson with numbers 1-10 with wooden numbers puzzle (see a post here). And by 35 months, Adrian could complete3🅿️🌠 Period Lesson also with spindles (see a post here).


I strongly believe that learning and play compliment each other, so we would play a game: while keeping the numbers visible, I would give simple and fun instructions:

DSC_0226.JPG"Turn number two upside down."
DSC_0226.JPG"Hide number one behind your back," and so forth … 


As an extension, offer a child to shade over the number with colorful crayons.
