While sitting in a park, Sophia saw butterflies, bees, and ladybugs. The given bar graph shows how many of each insect she saw. How many insects did she see in total?

The first bar shows us that she saw six butterflies. The second bar shows that Sophia saw 10 bees. And finally, the third bar shows that she saw four ladybugs. To work out the total number of insects that she saw, we need to add six, 10, and four. Well, six plus 10 is equal to 16. And 16 plus four is equal to 20. This means that Sophia saw a total of 20 insects while sitting in the park.
