The operation tables were not something I wanted to buy. I felt they were easy enough to make at home, and I am completely happy with the results!
I used JMJ publishing’s file (which doesn’t seem to be working tonight, it seems to happen regularly lately), and printed it on label paper size 8 1/2 x 11.
I had DH cut out a wooden panel the same size as the tables, and sticked the label on it. (it holds very well)
Then to protect the label, I use plastic book cover (the one that is on sale everywhere now, for all back to school event…) to cover the tables. It takes a little practice to put on properly but after a few tries, it becomes super easy.
And voilà, addition tables. I like the feel better then a plastified piece of paper.
This is their current location, behind the boxes of equations (also from JMJ publishing) and the tiles for the addition board (located just behind the tables)
