We have had a lot of school cancellations due to the weather lately (our city’s coldest February in 150 years!). On those no-school days, I’ve had to devise a plan to keep my kids busy and learning. We’ve been printing some worksheets from ぷりんと きっず (Japanese study free paper website). It has activities that are PERFECT for my preschooler and first-grader. I plan to use this site to keep my kids learning during their summer break as well!
This is just a small sampling of what’s available on the website. There are learning activities for grades preK-3rd grade, with plans to add more. There’s practice worksheets for hiragana, katakana, kanji, telling time, reading a calendar,counting money, etc. You can see all the subjects covered here on their sitemap. Here are the top 10 worksheet from the site:
You can “like” them on facebook to stay up to date: https://www.facebook.com/print.kids.net
I encourage you to visit Print Kids and browse around. You are sure to find something for your kids or yourself!

Thank you for the wonderful resource! I work with children so it is great to find any additional websites, esp. if they have free educational content.
I had a some what related question that I am hoping you could answer for me. One of the online shops that I frequent has been adding more books to their website, including puzzle books. I was interested in ordering some but I’m not sure what to order. A lot of the covers of the puzzle books look very cute and I think they are aimed at children but I am not 100% sure. I keep coming across terms like “arrow”, “skeleton”, etc (I think that the term “Tsunagi” refers to dot-to-dot puzzles). I’m thinking of puzzles/activity pages that could be used in an English speaking setting (little or no Kanji, Hiragana, or Katakana) that could be used for children even if they do not know Japanese like coloring, dot-to-dots, mazes, telling time, etc. I appreciate any information or advice you could offer me on the topic.
The print kids had no English version that I found .you have very good teaching material but I need the free printables in englisht
