Subtracting a whole ten or a whole hundred is quick mental subtraction: only the tens digit or the hundreds digit changes, and sometimes a second digit when the answer crosses into the next hundred. On this worksheet your child subtracts a whole number of tens or hundreds from another number and writes the difference, with no column to set up. Building Confidence takes whole tens from a two-digit number, On Level takes whole hundreds and whole tens from three-digit numbers, and Challenge Me uses differences that cross a hundred, such as 530 - 80.
Encourage your child to subtract the tens or hundreds first and to say the answer aloud, as in 356 - 40: three hundred fifty-six, forty fewer, three hundred sixteen.
Common Core standard: 3.NBT.A.2
356 - 40: subtract the tens, 50 - 40 = 10, so the difference is 316.
