This PDF file can be used to teach rhythmic and melodic elements that are found in "Deck the Halls" They slides can be converted into a PowerPoint or, if you email the seller, the original Powerpoint can be emailed to you. (The original contains the use of MusicEd font, which is why it is unable to upload in its original format)
The PDF also includes flashcards for dotted-quarter-eighth note patterns in both 4/4 and 3/4 meters.
It also includes a song match game that can be used as an assessment. All directions on how to use the PDF can be found on my blog, which is on the first slide of the file.
