Here is a full set of fraction manipulatives to help teach students fractions.
This set includes:
1, 1/2 , 1/3 , 1/4 , 1/5 , 1/6 , 1/8 , 1/10 , 1/12
I have made these so the total height is 2mm tall and a full plate can be printed within 90-120 minutes using only 50g of filament.
You are welcome to make them thicker if you would like to make them more durable.
