Here are Matthew’s weekly activities. Today is Sunday. What activity will he do today? And then we are asked another question. Today is Sunday. What day was it yesterday?
To help us answer this problem, we’re given a table. On the top row, it shows us all seven days of the week in order. And the different activities that Matthew does on those days of the week are on the second row. Let’s read the table to see how Matthew spends his time. On Monday, Matthew goes to the park. On Tuesday, he reads a book. On Wednesday, he walks the dog. He plays football on Thursday, has a music lesson on Friday, and then it’s the weekend. On Saturday, he goes swimming. And on Sunday, he plays on the computer.
Our first question asks us, what activity will he do today? And we’re given three possible answers. Will he go swimming, play on the computer, or will he go to the park? Now, the word today in this question isn’t talking about the day that you’re watching this video or trying to solve the problem. It could be a Wednesday when you watch the video. For some people, it could be a Friday. Instead, we’re told the day of the week. The question tells us today is Sunday. So we could replace the word today in the question and read it differently. What activity will he do on Sunday?
Let’s look at the table to find out. At the day of the week, Sunday comes after Saturday and before Monday. So we can find it in the last column of Matthew’s table. So now we found the correct part of the table. We can see the activity that Matthew does. If today is Sunday, Matthew will play on his computer.
Let’s look at our second question which is also about the days of the week. Today is Sunday. What day was it yesterday? The word yesterday means the day before today. But when’s today? We could be watching the video on a Tuesday or a Saturday. Again, the question tells us which day today is. Today is Sunday. So we can read the question in a different way. What day was it the day before Sunday?
We know where Sunday is on Matthew’s table, comes after Saturday and before Monday in the days of the week. And so we just need to look and see which day was before Sunday — Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. The day before Sunday is Saturday. And so if today is Sunday, yesterday it was Saturday.
