Is It Larger? Is It Smaller? - Greenwillow Books Prebound Edition | Fun Size Comparison Learning for Kids | Perfect for Preschool & Kindergarten Classroom Activities

As with the other TH books I have, this concept book works really well (my fav is Shapes Shapes Shapes, which I'd also recommend). Rather than explaining the concept, kids can see the idea. The fact that there are many versions of the idea makes it so your kids can have a positive experience, since once they get the idea, they can show you that they know it, over and over. The pictures are attractive, if a little 70s/80s.This is also a great book to have around for early book-enjoyers, especially as something your kid can do while you're busy. I got this when my son was 1 and already enjoying books. Since there are no words in the book, he could look through it and experience it without me looking over his shoulder. A good alternative to, e.g., television, if you need a little break.
