Sesame Street - Elmo's 123s — About this game
The staircase menu leads to counting stars, matching a displayed number, addition and subtraction. The pictures turn each question into something you can count rather than a bare equation. A wrong answer gives another chance to try, making it useful to point to the stars and say the total before choosing. Begin with counting, then move to combining or taking away groups when the number pictures feel familiar.
