Question Video: Reading and Writing Numbers up to 100 Using a Place Value Model Mathematics • Second Year of Primary School

Video Transcript

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.
