Being a substitute teacher means embracing the unexpected. One moment, you’re sipping your morning coffee, and the next, your phone buzzes with an urgent request to cover a class. Whether it’s a same-day call or an assignment you learn about the night before, last-minute substitute teaching requires quick thinking, adaptability and preparation. To make these transitions smoother, here are some actionable tips to help you stay ready for any last-minute teaching gig. 

Have a Go-To Substitute Bag

A well-prepared substitute teacher always has a “sub bag” ready to go. This bag should contain essential items that can help you succeed in any classroom environment. Consider including: 

• Dry erase markers and pens – Many classrooms run out, and having your own ensures you can always write on the board. 

• Sticky notes and index cards – Great for quick activities, notes to students or communication with the teacher.

• Classroom management tools – Stickers, reward tickets or even a small book of brain teasers can help keep students engaged. 

• A notebook or clipboard – Jot down notes about the day, observations about students and anything the teacher should know when they return. 

• A backup lesson plan – Sometimes, lesson plans may be missing or unclear. A short story with discussion questions or a simple math review worksheet can be lifesavers. 

Know Your District’s Schools and Policies

If you frequently substitute in Kansas or Missouri, familiarize yourself with the schools where you may be placed. Each school has unique procedures, schedules and classroom cultures. To stay prepared: 

• Review the district’s policies on classroom management, dress code and emergency procedures. 

• Bookmark school websites for quick access to bell schedules, staff directories and school policies. 

• Take note of parking and check-in procedures to save time upon arrival. 

Master the Art of Quick Lesson Prep

Sometimes, you’ll walk into a classroom with no lesson plans left behind. In these cases, having a few go-to lesson ideas can save the day. Here are some easy, engaging activities that work across grade levels: 

• Elementary: Read a short picture book and have students draw or write about their favorite part.

• Middle School: Facilitate a structured discussion on a current event or ask students to write a short story. 

• High School: Lead a debate on a thought-provoking topic or have students summarize and present key takeaways from their current lesson. 

Websites like Teachers Pay Teachers and Education.com offer free worksheets and activities that you can print or access digitally in a pinch.

Build a Routine for Last-Minute Calls

When you receive an early morning call for a substitute job, a streamlined morning routine helps get you out the door quickly. Consider: 

• Laying out professional, comfortable clothing the night before to avoid scrambling in the morning.

• Keeping your sub bag and any essentials (keys, ID, lunch) in a designated spot so you can grab them on the way out. 

• Having a quick breakfast option ready – A granola bar, yogurt or smoothie can keep you energized. 

• Saving school contact numbers in your phone to call if you have any questions before arriving. 

Develop Strong Classroom Management Skills

Since you’re stepping into an unfamiliar classroom, effective classroom management is key. Here are some strategies to establish authority and maintain a positive environment: 

• Set expectations early – Clearly state behavioral expectations at the beginning of class. 

• Use names whenever possible – If a seating chart is available, use students’ names to build rapport and maintain control. 

• Engage students quickly – Start class with an attention-grabbing activity to minimize disruptions. 

• Be flexible and patient – Expect the unexpected, and don’t be afraid to adjust your approach based on the class dynamic. 

6. Stay Connected Between Assignments

Between substitute teaching assignments, it’s helpful to stay engaged and ready for future opportunities. Consider: 

• Joining substitute teacher groups on social media – Kansas City has several Facebook groups where local subs share job openings and tips. 

• Attending professional development sessions – Many school districts offer workshops for substitute teacher training. 

• Signing up for multiple districts – Expanding your network increases your chances of consistent work. 

Maintain a Positive Mindset

Last-minute substitute teaching assignments can be stressful, but embracing them with a positive attitude makes a difference. Students respond well to enthusiastic, engaged teachers. Even if you only spend one day with a class, your impact can be significant.

Final Thoughts

Being a substitute teacher requires flexibility, resilience and a proactive mindset. By staying prepared with a go-to substitute bag, having backup lesson plans, building a solid routine and sharpening classroom management skills, you’ll be ready for any last-minute assignment that comes your way. Whether you’re covering a third-grade math class or stepping in for an IT support role, your ability to adapt makes you a valuable asset to any school.
