Counting Crabs brings numbers 1 through 20 to life with 10 double-sided crab toys that turn early math into a hands-on matching game. Each crab shows a ten-frame visual on one side and the matching numeral on the other, helping kids connect what they see (quantity) with what they read (number symbols). Numbers 1 through 10 appear on the front, while 11 through 20 hide on the back, giving children a compact set that covers a full range of counting practice. The design supports number recognition, counting skills, and early place value understanding through tactile play. 10 double-sided crab toys teach numbers 1 through 20 with flip-and-match play Ten-frame visuals on one side, numerals on the other help kids see the relationship between quantity and number symbols Front side covers 1 through 10, back side tackles 11 through 20 for progressive learning Hands-on number matching builds counting skills, number recognition, and introduces early place value concepts Works in classrooms, early learning centers, or at home for interactive math practice
