5 Effective Strategies for Improving Your Math Warm Up Activities

Are your daily math warm up activities engaging enough to truly capture your students’ focus?

The most effective lesson-opening activities (engagement hook, anticipatory set, warm-up, etc) do two things: assess your students’ prior knowledge and build anticipation for the lesson ahead.

Achieving this goal requires a solid mix of fun and engaging strategies and activity ideas (and rarely relying on assigning routine practice problems).

For some awesome tips and activity ideas for how to improve your warm up activities and make the most of the first five minutes of your lessons, check out my brand new list of effective strategies:

---

1.) Show a Video Clip

Some math concepts are meant to be seen, and sometimes your students will need visual aids to help grasp complex mathematical ideas. By starting class with a short video clip, you are engaging your students’ ability to think about math visually—a mindset which will sustain throughout the remainder of the lesson, to everyone’s benefit.

Try It! Try using the video clip of Unit Rates in the Real-World below prior to teaching a lesson on solving word problems involving unit rates.

2.) Puzzles and Challenges

Engaging math challenges and puzzles are a great tool for giving your kids opportunities to have fun while problem solving and thinking mathematically at the same time, especially if you want to prevent them from growing bored of routine practice problems.

Try It! Try sharing this fun math puzzle with your kids at the start of your next lesson and watch your students’ engagement and interest skyrocket!

3.) Which One Doesn’t Belong? (WODB)

Instead of working on practice problems during a lesson's warm-up, students will be shown 4 somewhat related images and have to apply their reasoning skills to decide which of the images does not belong.

And here’s the catch….WODB activities do not have a single correct answer. The activity is designed to be interpreted in a variety of different ways in order to spark deep mathematical thinking and discussion (in small groups, whole class, or both).

Try It! Try using the WODB graphic below prior to a lesson on percentages.

4.) Think-Notice-Wonder (Writing Prompt)

Think/Notice/Wonder is a great strategy for getting your kids engaged in math writing every day.
