A Fun & Innovative way to learn the 4 operations of Maths!
Start the string with the 1st number on the left, read the large number in the center, find the correct answer on the right hand side & bring the string to the answer. (example 3+1). Then draw the string around the back to the next number on the left. Repeat this procedure until the whole exercise is completed. It has a self-correcting mechanism with answers at the back too. The next challenge would be to time yourself.
