Pick-up puzzles are essential as an introduction to finger play and puzzle play. The number of "stars" drawn on the ladybug's back matches the "number" hidden under the ladybug piece. Also, the number drawn below is the same color as the color of the ladybug's back. Through finger play, this puzzle allows for various ways to play, such as comparing sizes, counting numbers, and recognizing numbers and colors. My child often played with this around the age of two.
