Start by remixing this project. Add a backdrop scene for each part of speech. (You might need to change these after you've written your sentences, but just pick something for now.) Adjust the code for the Header and Example Sentence sprites to change when the correct backdrop shows. DRAFT your sentences in Google Docs, first. Be sure your spelling and grammar are correct before you paste them in the costume text boxes. Paste the example sentence costume text to the sentence you are using to illustrate the corresponding part of speech (TARGET word(s) in CAPS). You may need to adjust line breaks or text box size. Add costumes for the main sprite as needed to illustrate your sentences, and adjust the code to show the correct costume according to the backdrop. Add more sprites ONLY if you need more characters to illustrate your sentence. Remember, a sprite can have multiple costumes, and change them in response to an event!
