DK Children's Encyclopedia (2022)

DK Children's Encyclopedia, revised 2022 edition DK's answer for ages seven to nine, and the easiest encyclopedia here for a child to use alone. Each of its more than 250 topics gets a single page, with a short explanation and plenty of pictures, so a child can look something up and finish the entry before losing interest. That one-page rule is also its limit: answers stay brief, and a curious ten-year-old will want the Knowledge Encyclopedia next. The 2022 revision added 16 new pages and updated existing ones, so pass over the 2017 first edition if you see both.
