Fourth grade takes the facts learned in third and stretches them over more digits. Every problem pairs a two-digit number with a single-digit one - 10 to 99 by 0 to 9 - which is the step where a student has to hold a partial product or a remainder in their head rather than recall an answer.
Twenty problems fit on a page, because each one is now several steps rather than one. Multiplication and division are both on, so the page moves between them; untick either to spend a session on one.
Use the Long Division page, which lays the problems out in the bracket format with room to work underneath rather than as a single line.
Set both ranges to two digits for two-digit by two-digit problems, which is where fourth grade usually finishes up. Double Digit Multiplication is set up that way.
