Subtract from Whole Hundreds: what children learn
Subtracting from a whole hundred means trading twice: 300 becomes 2 hundreds, 9 tens, and 10 ones. Then 300 - 45 = 255.
Subtract from Whole Hundreds: worked example
300 - 45 = 255
300 is 2 hundreds, 9 tens, and 10 ones. 10 - 5 = 5 ones, 9 - 4 = 5 tens, and 2 hundreds stay. So 300 - 45 = 255.
Subtract from Whole Hundreds: a common mistake to watch for
Kids get stuck because the tens and ones are both 0, and they try to subtract 0 from 5.
Subtract from Whole Hundreds: how to help at home or in class
Show the nines trick. For 400 - 36, first work out 399 - 36, which is 363, and then add the 1 back to get 364. Each digit of 399 is large enough to subtract from, so no trading is needed along the way. Have your child compare this result with a column answer to see the two match. When they use the trick or the double trade confidently, they are ready for two-digit subtraction in columns.
