In Sizes, beginning readers compare different animals of similar habitats by their sizes, such as a short fish and long whale in the ocean and a small frog and big elephant in a forest. Carefully crafted text uses high-frequency words, repetitive sentence patterns, and strong visual references to support emergent readers. A Let's Review! question asks readers to sort animals into groups of big and small.
Sizes is part of Jump!'s Let's Sort! series.
