ROTARY LOOKUP CALCULATOR

Description Rotary lookup calculator   This is a rotary lookup calculator to help children with their math.   The rotary calculator has removeable slices. There is a set for addition, subtraction and multiplication up to the table of 12. By replacing the slices, you can teach your child addition, subtraction or multiplication.    This is one of the parts from my other model The Math Game   Each slice has its location printed in the lower right corner and a “+”, “-“ or “x” (for the sets) in the lower left corner. You need to match the slices with the number on the rotary lookup calculator base. For example, the “12” slice would be inserted in slot “12” of the base.   The rotary lookup is very easy to use and is meant to allow children to verify their answers by themselves. To use it you simply line up the numbers and the arrow will point to the answer.   For example, if you spin the numbers 9 and 7. You would spin the rotary lookup calculator so that 7 is aligned with the number 9 and it will point to the answer which is 63.   3d printing   You only need to print the math set you need (multiplication, addition or subtraction). About me   I enjoy creating 3d models that others can use and appreciate. It is a very fun pastime. I find it very rewarding to see my models downloaded and printed. I put lots of thought, time and effort to create each model print out multiple iterations to make sure it works just right. If you liked my model and wish to encourage me please give it a like.
