Lochkasten card set Subtraction to 20 | Year 1

Subtracting within 20, each exercise a little harder than the last. Ideal for practising in between, without a worksheet and without a red pen.

How the Lochkasten works: slide the card set into the wooden box, put the wooden pin into the hole next to the right answer and pull the card. If the answer is correct, the card slides out - if it is not, it stays put. So your child sees for itself whether it was right and needs nobody to check.

Kölner Lernspielverlag builds learning games that work without a screen and without grown-ups. The base units are made of wood, the learning cards of thick, durable paper. Because the card sets can be bought individually, the game grows with your child over years.
