In years past, some of my students have struggled with counting a dotted quarter note, even though I felt I taught the concept well and we practiced the rhythm many times. This year, I decided to try teaching the dotted quarter note differently and I feel students were able to understand how to count a note worth 1.5 beats much more easily.
I happened to have a bag of cookies on hand, so I used cookies in my lesson, but you could use anything else to represent the beat as long as you can break it in half.
First, I drew 4 quarter notes on my white board and I selected 4 students to come up and stand under each of the notes I drew. I gave each student 1 cookie which they were to hold out in front of them to represent 1 beat. We counted the 4 quarter notes together as a class by saying "Yum, Yum, Yum, Yum" - (Yum = 1 beat). Next, we counted the quarter notes by saying "1, 2, 3, 4".
Next, I added a dot to the first quarter note and told students that now, the first quarter note is called a dotted quarter note and it gets more cookie! It gets to steal half of beat 2's cookie. The student under beat 2 had to break their cookie in half and give it to the beat 1 student. I then showed students how we have to change the 2nd note to an eighth note...because now that student only has 1/2 of a cookie left.
We then practiced counting the dotted rhythm...holding the dotted note through beat 2 since they had more cookie. At the end, I let students eat the cookies. Today, when I asked students how many beats were in a dotted quarter note, they said, "One and a half cookies!"
