Diana is using the special pen to select the correct response to the time at the top of the card.
If the correct answer is selected the pen turns on a green light. It also plays music or says an encouraging phrase for the child.
If a wrong response is chosen, the light on the pen is red. The pen also makes a beeping sound and tells the child to try again.
The purchased games come in nice recipe-sized boxes. They have them for several different math and phonics skills. We have clocks, money, addition, subtraction, multiplication, division, beginning letter sounds.
But what really makes Hot Dots versatile is the extra dots you can buy. There are two sheets of COLD dots (wrong answer) and one sheet of HOT dots (right answer) in each package. The pens can also be purchased separately. I have made lots of other games for the grandchildren using these dots.
I don't often promote purchased games....but we really like these. ...and the skill possibilities are endless!
