A few months ago, I made some DIY sandpaper numbers for my son. So far, he has been enjoying using them in our works. Not only have they been on our shelves almost everyday since I finished them, but we use them to sing a silly number song regularly!


Because I have been getting questions about how I made these, I am very excited to share with you exactly how I put these together as well as the printable I used for getting the d’nealian font!

DIY Montessori Materials: Sandpaper numbers

This is the first time I am sharing such a ‘DIY’ tutorial so if there is something that is not clear or you need a few extra tips, please don’t hesitate to ask!


  • Plywood – 10 blocks
  • Sandpaper*
  • Numbers printable
  • Scissors
  • Heavy duty glue (or a hot glue gun)
*Note: for the sandpaper, I went with a fine sandpaper that would not be too rough on my son’s fingers. These numbers can serve as a fabulous pre-writing activity by having your child trace them with their fingers.
Additionally, be sure to have a small reserve of the sandpaper leftover that you do not use for the numbers. You may need this to sand any rough edges of the wood to avoid splinters.


  • Get your plywood down to size. You can either purchase your own pre-cut pieces or saw them yourself. Mine ended up being 12.5 by 15 centimeters and 1/2 a centimeter thick. I found this size to be large enough to have one number fit clearly and also light enough for my son to handle.
  • Sand the edges of the wood to avoid splinters (important!)
  • Print the numbers printable on normal paper
  • Cut out the numbers
  • Trace the cut out numbers onto the sandpaper. To avoid marks on visible side of the sandpaper, I placed the numbers backwards on the REVERSE side of the sandpaper.
  • Cut out the sandpaper numbers
  • Glue them (carefully) in the middle of the plywood blocks
  • Let dry
  • Use as much as you want!
