Sudoku for 6 Year Olds (Free Printable 6×6)
Six is the age to step up to the 6×6, with numbers 1 to 6 and boxes that are three wide and two tall. It is meatier than the 4×4 but still finishes by scanning for the missing number. This page starts at Beginner on the bigger grid; if it feels long, the 4×4 is one click away.

What a 6×6 sudoku for age 6 looks like

First-grade sudoku: moving from 4×4 to the 6×6 grid
The jump from four numbers to six is the biggest one a young solver makes, because the boxes stop being square. A 6×6 box is three cells wide and two tall, and a six-year-old needs a minute to see that the box rule is the same rule with a different shape. Beginner leaves only a handful of cells empty so that minute happens on an easy page. After that, Easy is the working tier for most of first grade.
First-grade teachers print a class set at Easy for the same reason kindergarten teachers print the 4×4: one rule, nothing to teach, and every puzzle has exactly one answer so checking against the key takes seconds. If the 6×6 stalls, drop back to the 4×4 at Medium for a week; momentum matters more than grid size.
