Time Management, especially for those larger tasks and projects, can be a tricky skill to teach. I have been using this "Classroom Weekly Goal Planner" in my classroom to teach my students how to prioritize their goals by planning out their tasks for the week.
The "Classroom Weekly Goal Planner" allows students to choose 3 goals for their week, and organize their daily tasks, so they can accomplish these goals. If you are inclined, you can do one with them at the start of each week to track their productivity! Perfect tool to show parents. Enjoy!
