A farmer gathered 892 chicken
eggs. 10 were broken. How many eggs are left?
Can you see what we need to do to
find the answer to this problem? Let’s sketch a bar model to help us
understand. Firstly, we’re told that a farmer
gathered 892 chicken eggs. The next thing we’re told is that
10 of these eggs were broken. And we need to find out the number
of eggs that are left. Can you see what we need to do to
find the answer? We need to take away 10 from
892.
Now we know that our starting
number, 892, is made up of eight 100s, nine 10s, and two ones. And the number that we’re taking
away is a number of tens, isn’t it? It’s a multiple of 10. In fact, it’s one 10. It’s only 10. If we look at the number we’re
starting with, this three-digit number, we can see that there are nine 10s. And this digit, nine, is all we
need to focus on because, as we’ve said, what we’re subtracting is a number of
tens. We have nine 10s. And if we take away one 10, we’re
going to be left with eight 10s. We’ve used our knowledge of place
value to help us answer this question. We could just focus on the tens
digit. If a farmer gathered 892 chicken
eggs and 10 were broken, the number of eggs that are left is 882.
