Set up a "homework options" chart. Maybe put a weekday at the top of each column, allow them to choose from that column. Staple to the top of all completed hw on Friday, with their choice for each night colored in/signed.
Here’s an easy way for students to practice their spelling words. Have them draw a big scribble on their page – remind them to leave big spaces in their scribble! Using coloured pencils, they can then fill the spaces with their words.
I do not believe that giving students a list of words and telling them to memorize it for a test is super effective. I think this spelling activity would encourage students to make relationship to the words, while reinforcing some vocabulary as well.
