Yesterday, Today, and Tomorrow

In this video, we will learn how to use the words “yesterday,” “today,” and “tomorrow” to describe when events occur.

Today is the day which is happening now. Yesterday is the day before today. Yesterday is in the past; it’s already happened. Tomorrow is the day after today. Tomorrow hasn’t happened yet; it’s in the future. So today is the day which is happening now. Yesterday is the day that happened before today. And tomorrow is the day that comes after today.

If it’s Thursday today, what day was it yesterday? We know that yesterday is the day before today. The day before Thursday is Wednesday. So yesterday, it was Wednesday. If today is Thursday, yesterday was Wednesday, then tomorrow must be Friday. Tomorrow is the day after today.

Let’s try some questions now to help us practice using the words “yesterday,” “today,” and “tomorrow.”

Here are Matthew’s weekly activities. Today is Sunday. What activity will he do today? Will he go to the park, go swimming, or play on the computer? What day was it yesterday?

We’re shown a chart of Matthew’s weekly activities. On Mondays, he goes to the park. On Tuesday, he reads a book. On Wednesday, he walks the dog. On Thursday, he plays football. On Friday, he has a music lesson. On Saturday, he goes swimming. And on Sunday, he plays on the computer. The first part of the question tells us that today, it is Sunday. What activity does he do on Sunday? We can tell from the chart that on Sundays, Matthew plays on the computer. So if today is Sunday, the activity he will do is play on the computer.

The second part of the question asks us what day it was yesterday. We know that yesterday is the day that comes before today. And we know that today, it’s Sunday. The day before Sunday is Saturday. If today’s Sunday, Matthew will play on the computer. And yesterday was Saturday.

The table shows the weather conditions this week. Yesterday, it was cloudy. What will the weather tomorrow be?

We’re shown the weather conditions for this week in a table. On Monday, it will be sunny. And it will be sunny on Tuesday as well. On Wednesday, it will be cloudy. On Thursday, it will be rainy. It’s going to be stormy on Friday, sunny on Saturday, and rainy on Sunday. We’re not told what the day is today, but we know that yesterday it was cloudy. On which day was it cloudy? It was cloudy on Wednesday. So we know that yesterday was Wednesday because it was cloudy on Wednesday. We know that yesterday is the day that comes before today. If it was Wednesday yesterday, it must be Thursday today.

Now that we know it’s Thursday today, we can work out what the weather will be tomorrow. Today’s Thursday; tomorrow is Friday. And the weather on Friday is stormy. The weather tomorrow will be stormy. Yesterday it was Wednesday. Today it’s Thursday. Tomorrow it’s Friday. And the weather tomorrow will be stormy.

What have we learned in this video? We’ve learned how to use the words “yesterday,” “today,” and “tomorrow” to describe when events occur.
