Build-the-Greatest-Whole Number

Build-the-Greatest-Whole Number is a place value card game about making the largest possible four-digit number from digits revealed one at a time. Players must commit each digit to a position on a place value grid before they know what will come next. That uncertainty turns a simple “make the greatest number” task into a strategy problem about thousands, hundreds, tens, and ones.

Use it when students are practicing place value and comparing multi-digit whole numbers. The best discussion comes after the digits are revealed: which placement decisions helped, which hurt, and what would students change if they could replay the round?
