Secret Message Puzzles (or Cryptograms) are great for teaching problem solving, letter combinations and reading, science, and computer programming. And they’re super fun, too! This packet has 100 puzzles, each one at 3 difficulty levels. Every puzzle prints on a half sheet of paper. Kids will need to use their knowledge about common letter combinations and words to solve the riddle. The PDF packet includes color, black and white, letter, and A4 (international) versions of all the puzzles, and there's an answer key at the back.
