Lernen, Lachen, Selbermachen is a new booklet series by Ravensburger. The booklets offer short, fun, and engaging activities for children to experiment and play with letters and numbers. The booklets are relatively affordable and you can order them via Amazon. When I bought Buchstaben-Sticker-Rätsel it was EUR 4,99 on amazon.de and $9.11 on amazon.com.
Buchstaben-Sticker-Rätsel
We have the Buchstaben-Sticker-Rätsel booklet (we are not quite there yet with numbers). It has coloring options, mix and match activities, and stickers that need to be put in the right place. Especially the coloring options and the stickers are very motivating and engaging!
The books are labeled as 5 years and up (ab 5 Jahren), but Ella who is now 3.5 years is getting the Rätselbuch out and successfully works on a page here and there. The content seems pretty similar to some of the activity sheets that she brings back from her U.S. preschool.
So if your child likes coloring and stickers and is in the process of getting to know letters and numbers, give this series a try!
