Summary

These were one of my favorite math manipulatives when I first started working with fractions back in the day. The tray makes this something that stores well, and the blocks are all numbered by size.

Source files for the whole project as well as each piece individually are included for you to print as you like!

Edit: I uploaded a new "1" fraction block where the direction of the number matches all the other blocks... print whichever you like!

Instructions

Put together in Tinkercad... the poor man's cad solution :)

These can be printed separately into whatever combination you like. I have a friend who is a third-grade teacher and they are always looking for these in 2nd and 3rd grade so I figured it couldn't hurt to have some for ourselves.

I guesstimated some depths of numbers because we didn't have a 3D printer to test it out when I designed it. Almost 8 years later I've finally printed this and updated the tray to better fit the pieces
