Maths Seesaw

cults3d

Using the natural force of gravity, this educational device works well, to explain and demonstrate, with hands experience, simple Math. There are ten pegs on either side on the Math beam, each peg is numbered 1 through to 10, from the center out. You may print up to 20 Beam Counters, and use these to explain Math problems like Addition, Subtraction and Multiplication. Basically on the left hand side place the Counter on any numbered peg or pegs. Lets say you have place a single Counter on the peg number 10. On the right hand side you can demonstrate that two Counters on the peg numbered 5 balances the Math Beam so as to align the Math Beam pointer. This would show the actual result of the following two equations (5 +5 = 10) or (2 x 5 = 10) Subtraction can be demonstrated placing say a Math Counter on the pegs numbered 8 and a Counter on 4 on the left hand side of the Math Beam. Then on the right hand side of the Math Beam place a Math Counter on the 2 and one on the 10, this will balance the Math Beam. Then ask what if we subtract the Math Counter on the left hand side of the Math Beam from the peg numbered 4, what is the answer? The existing Math Counters on the right hand side would need to be replaced by a single Math Counter on the peg numbered 4. This would solve the equation (8 - 4 = 4). Each peg on the Math Beam can hold up to four Math Counters, so groups can also be demonstrated as well. I have been testing this Math Seesaw on my 8 year old grand daughter and she has so much fun with it, that I thought I would allow other parents and guardians, the opportunity to 3D Print this great little educational device, enjoy! A warning that I would make is that as this device has small parts that it be kept out of the reach of person under the age of 5 years. We do not take any responsibility for any parts of this device being printed and possibly being place in the mouth of a your child. Please use strict adult supervision, when using this device with any persons young or old that may place the small parts in their mouth, thank you!
