Adding 3,400 + 2,500 is the fact 34 + 25 with the zeros put back, and 9,000 - 4,000 is 9 - 4. Each sheet has twelve bare problems, sums and differences in turn, with a line after the equals sign, and your child writes the answer without a column. Building Confidence uses tens and fifties inside 1,000, On Level hundreds and thousands, and Challenge Me answers that cross a thousand or ten thousand.
Common Core standard: 4.NBT.B.4
3,400 + 2,500 = 5,900, because 34 hundreds + 25 hundreds = 59 hundreds.
Losing a zero, so 800 + 600 becomes 140 instead of 1,400.
Do the basic fact first, then say the unit: 59 hundreds is 5,900.
