Why are there 4 ways, not 10? Because what kids can produce with quality is more than fine.
Kids are free to write the way they think it is correct in my class, since they are able to write in another language (Portuguese in this matter), they try their hardest in English.
That is a typical example of their writing. You sing = using. Do not worry! On our sight words on the right time will get correctly written.
Nice work! I found it hilarious the lightbulb inside of the TV.
Anyways, write can be fun for bilingual classes.
