These laser cut number blocks are useful in helping school-aged children visualise numbers and quantities in order to improve their understanding of mathematics. These blocks can be used to help understand place value, addition and subtraction, and to help understand equal quantities. Notes: The scored numbers can be turned off in the interface to reduce cut time. If using opaque acrylic, painting the pieces before removing the masking will help make the score lines/numbers stand out. It looks amazing in fluorescent acrylic, but mirror the file before laser cutting and scoring to keep the surface smooth.
