BAJO Wall Abacus C (99790). 25 x 26 x 7cm. Recommended for 18mths and up.
New from BAJO, this beautifully made abacus can be used standing or laid flat, and can be turned over to reveal monochrome counters on the reverse. Jumble all the counters up, then work out how to slide them back into their orderly places! An excellent first sorting and counting tool.
