If you're working on meter in your classroom, here's an engaging lesson that'll test your students' math skills! In Sign of the Times, we do a brief introduction of meter (from there on called" Time Signature"). After the introduction, we talk about how measures (musical sentences) are formed and how composers have the freedom to write different beat patterns in music. The lesson in PDF format (also included is the video along with an editable powerpoint file) continues with illustrations of 4 types of time signatures, and gets into the game format -- a measure with combinations of quarter, eighths, whole, and half notes will appear in the staff and students will have to guess the time signature. On the next slide, the answer will appear. I like to do this boys vs. girls -- they have to use their quick thinking to add up the beats! Some are easy to moderate, but as we progress it gets a little harder! If you have any questions, please feel free to leave a comment... that's the sign of the times!
