Noah and Emma tried to read the
number given. Emma said it is 74, and Noah said
it is 47. Who said the right answer?
Noah and Emma are trying to work
out which number is shown in the model. We know it’s a two-digit number
because it has an amount of tens and ones. Emma thinks the number is 74, and
Noah thinks the number is 47. Let’s count the tens and ones to
find out who’s right.
How many tens are there in the tens
part of this number? One, two, three, four, five, six,
seven. So, we can write a seven in the
tens place. Did you count the ones? There are four. Seven tens and four ones is 74. So, Emma was right. It looks like Noah wrote the tens
and ones digits the wrong way round. The number given is 74. So, Emma was right.
