BumbleBee’s 123s is Designed to Give Your Child a Head Start in Math & Counting. Traditional number Videos & Apps teach children to recite sequences of numbers, but fail to teach math or quantitative reasoning skills. BumbleBee’s 123s focuses on the presentation of mathematical reasoning skills. 123s introduces the numbers 1 to 10 as well as the one-to-one correspondence of an object and number when counting and helps build logical ordering skills. BumbleBee’s 123s includes interactive games and flashcards.
