The Learning Resources Numberblocks Number Sequences Puzzle Set playfully introduces children to number sequences from one to twenty. The set contains 50 puzzle pieces that can be put together to create ten double-sided educational puzzles. The colorful pictures feature the familiar Numberblocks characters, which clearly visualize counting and ordering number sequences such as 1 to 5 or 1 to 10. Thanks to the precisely fitting, wave-cut edges, the puzzles are self-correcting: only the matching number strips can be joined together in the correct sequence. This allows children to check number sequences independently, reinforce their understanding of numbers, and train their fine motor skills at the same time.
