In this video we explain the difference in using "bad" and "badly". The key difference is that 'bad' is used as an adjective and 'badly' as an adverb. Therfore, 'bad' describes that something is not good, while 'badly' refers to something that is done in a bad manner, harmfully or in correctly. A good example sentence for 'bad' would be "Jenny had a car accident today. This is bad". Let's look at an example for 'badly': "Austin behaved badly". I'm sure you'll never confuse the two words again.
This unit was about the two productive skills: speaking and writing. Writing can sometimes be neglected in the classroom. It is a difficult skill and takes a lot of practice, especially for students who do not use the same alphabet. Handwriting is very personalized and everyone should not be fit into the cookie cutter. Though, I often correct the same writing mistakes in my students. My Japanese students often write the alphabet letters with strokes as they would their own alphabet. This is usually a problem that I think will correct on its own.
