A perfect complement to Montessori classification work, each book in the set of three successfully isolates a single concept with clear, simple text and unambiguous photos.
I Know it is Living and I Know it is Nonliving contrast and compare the same key ideas (“It moves.” “It does not move on its own.” “It Grows.” “It does not grow.”)
Is it Living or Nonliving? illustrates the same ideas with examples from a child’s world. Paperback, 8 pages each.
