Sometimes it's hard to know how to pronounce the "-ed" ending of a regular verb in the past tense. Here are plenty of examples, taken from the story of the Ugly Duckling.

Let Sigrid tell you about the solar system that resolves around the Sun, including the order and characteristics of the planets within it. What is the closest planet to the Sun? What are the smallest and largest planets?

Many of us have to deal with traffic on a daily basis. Here's how to talk about it in English, include expressions such as "traffic jam," "bumper-to-bumper," and "bottleneck."

When we talk about traffic, it's not only about cars and trucks. We can talk about people on bicycles or on foot, too. They have some special rules to follow, especially in the city.

Sigrid shares what she has learned about having a swimming pool. As it turns out, having a pool is a lot of fun, but also quite a lot of work.

There are various things we need to do to keep the pool clean and the water circulating. Sigrid describes some of them. It's quite a lot of work, but she thinks that having a pool is still worth it.

In the first of three related lessons, we talk about the important and common word "point" as a noun in its most concrete form. We use "point" to talk about measurements, maps, numbers, and more.

In this lesson, we talk about the word "point" in its figurative sense, and as part of the phrasal noun, "point of view." In addition, we talk about verb, adjective, and adverbial forms.

In this lesson, we learn about the word "tip" and then we look at how it combines with "point" in the noun "the tipping point."

There's more than one way to talk about the weather. In part 1 of this lesson, we talk about it in the present. We use nouns, verbs, and adjectives to describe the weather.

This time, let's talk about the weather in the past using nouns, verbs, and adjectives. If we use the past tense, we can talk about yesterday, last week, last month, or even last year.

In this lesson, we'll talk about the weather in the future. One way to express the future is with "going to": "It's going to rain." The second way is with "will": "It will rain." You will hear both in this video, so keep your eyes and ears open!

In this video, Sigrid talks about the different types of two-dimensional shapes and some basic geometry.

We can use dots and circles to describe things figuratively. Sigrid gives us examples with expressions like "connect the dots" and "inner circle."

A square is a shape, of course, but there are plenty of ways we use squares to describe things figuratively. Let's look at some examples of when and how we do this.
