1. Turn the unit on and slide the switch on the bottom to addition or subtraction, and press the number you’d like to practice…
2. Read the problem, press the answer, and listen for the tones – positive if you’re right, negative if you’re not (missed questions are repeated at the end of the game, until they are answered correctly)…
3. Answer all of the questions correctly, enjoy a musical reward, and check your time. Play again and see if you can beat it!
Comments about Math Trekker™ - Addition & Subtraction:
My son received this in his Christmas stocking. I put it into the car. It isn't something that he will play for long periods of time, but it is a good time filler...especially in the car or when waiting somewhere (restaurant, doctor's office, errands). It is very easy to use and gets in some extra math fact practice.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
