How to Play Sesame Street: A-B-C & 1-2-3
Quick start
Begin with Astro-Grover for counting practice. In its activity menu, move Grover with the D-pad and press A or B to choose How Many Zips. Count the visitors, highlight the answer and press A or B. For shape practice, choose an introductory Magic Shapes activity, compare the table piece with the picture and use the D-pad to request another piece when needed.
Controls
D-pad selects activities and answers, changes the letter wheel's speed or cycles Duckie's path pieces. A or B confirms a choice, submits a number, accepts a shape, catches a letter or places a path piece. START or SELECT returns from the counting, shape and letter activities to their menus. In Big Splash, one press clears the puzzle and two presses return to its menu; these are not pause controls.
Sesame Street: A-B-C & 1-2-3 — About this game
This collection combines Astro-Grover, Ernie's Magic Shapes, Letter-Go-Round and Ernie's Big Splash. Grover's space visitors introduce quantities and arithmetic, while Ernie's magic act asks you to spot matching colors and shapes. The letter wheel moves from simple matching to short-word puzzles. For a change of pace, build a connected route that takes Rubber Duckie to Ernie's bath, checking the entrance and exit arrows on each piece. Choose an activity suited to the learner and work through its easier options before trying the more demanding puzzles.
