Flippity.net's Mix & Match Grid is a fun way to work on teaching about sentences with a little twist.
Students will need to create 4 parts to the sentence they create (site's example in bold).
1. Intro - Financed by the king and queen of Spain,
2. Subject - Christopher Columbus
3. Action - discovered the new world when he landed in
4. End - what is now the Dominican Republic.
Flippity does a nice job of always including the steps on how to use their templates (see pictures below).
I have also included a 2 minute and 30 second embedded YouTube video below.
If you have any questions please let me know.
