Endless Alphabet

Each word in Endless Alphabet gets its own short animation and an interactive puzzle where kids drag letters into place while each letter says its phonetic sound. The vocabulary is ambitious — words like "gargantuan," "cooperate," and "belch" — and the monster animations that demonstrate each word's meaning are genuinely hilarious. Kids pick up vocabulary far above their grade level because the visual definitions make complex words concrete. The Endless series (Reader, Numbers, Spanish) maintains the same quality.
