FAQ
What makes missing-number problems with 3-digit minuends more challenging than 2-digit versions?⌄
Students must track the hundreds digit while also reasoning about the missing value, requiring them to hold more information in mind and apply place value understanding more broadly.
If the problem is 450 – ? = 380, how would a student find the missing value?⌄
Students can subtract 380 from 450 to get 70, identifying the missing subtrahend — or they can count up in tens from 380 to 450 and count the steps.
How do these problems reinforce the relationship between addition and subtraction at larger scales?⌄
Any subtraction equation can be rewritten as addition (? + 380 = 450), which students should recognize as a universally applicable inverse-operation strategy regardless of number size.
