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.
Monthly Spelling Menus --- Spelling Tic-Tac-Toe with EDITABLE DIRECTIONS
Monthly Spelling Menus for the WHOLE YEAR! Each month includes 9 fun and engaging practice activities that kids LOVE! Also, includes an editable version which allows you to enter your own student directions.
Here's a FREE Speller's Choice Menu that can be used with any spelling list. The kids love it because there's a variety of activities to choose from, and teachers love it because these activities manage to incorporate phonics, grammar, writing AND math!!! :) I just place it in a sheet protector in their take-home binder for them to use with homework every night.
