There were 31 tomatoes and 43
strawberries growing in Emma’s garden. She picked eight tomatoes and 11
strawberries when they ripened. Find the equation that shows how
many strawberries are still growing in her garden. Is it 31 subtract 11 equals 20, 31
subtract eight equals 23, 43 subtract 11 equals 32, 43 subtract 11 equals 31, or 43
subtract eight equals 35?

There’s a lot of information in
this word problem. We’re being asked to work out how
many strawberries are still growing in Emma’s garden after she picks the ripe
ones. Emma had 43 strawberries in her
garden. This is the whole amount or the
number of strawberries she had to begin with. We’re also told that emma picked 11
strawberries, but we’re not told how many strawberries she has left. Our part–whole model helps us to
think about the subtraction equation. We know Emma had 43 strawberries to
begin with, and we also know that she picked 11 ripe strawberries.

So to find out how many
strawberries she has left in her garden, we need to subtract the 11 that she picked
from the 43 she had to begin with. We need to calculate 43 subtract
11. This is a tricky question because
two of the equations show 43 subtract 11. Is 43 subtract 11 32 or 31? If we start at 43, we need to count
back 11. 43 subtract 10 gives us 33. And because we’re subtracting 11,
we need to subtract one more. 10 and one more is 11. One less than 33 is 32. 43 subtract 10 is 33. 33 subtract one is 32. So 43 subtract 11 equals 32. The equation which shows how many
strawberries are still growing in Emma’s garden is 43 subtract 11 equals 32.
