Students correct three place value errors — digit 3 misplaced in 435,208, expanded form digits in wrong positions, and digit 2 misidentified in 1,208,564. Part B has four fill-in-the-blank questions about the value of 7 in 724,350, standard form from expanded form, and the place of 5 in 3,560,812. Part C has two short-answer questions about expanded form and how to determine a digit's value.
Correcting place value misidentifications builds the position-counting habit that prevents systematic errors in multi-digit numbers.
