Afternoon MN
DC has brought home a folded piece of card with interwoven strips.
Apparently...
The book works by when you close the front flaps you can then carefully open the inner book so the four sides which you can write on should have a multiplication and array the answer to the question on the inside and the inverse division question on the inverse so the outside may have 5×3 equals an array of 5 x 3 circles or dots and on the inside 2015 and then 15÷3 = 5.
If any of you out there know what the above means and can send me a link of a visual, I'd be much obliged 
Thanks in advance
