Tip #1 You can use the Word of the Week IN the jingle. It doesn't have to be one of the words that rhymes.
Tip #2 You can write the jingle ABOUT the Word of the Week, without actually using the word itself. The jingle would need to be CLEARLY about the word, however.
Tip #3 You can use the word in your jingle in the manner of an acrostic. For example, using the word "walk" as an acrostic might look like this:
We are heading off to school
And we never run or skip,
Lest we fall on hands and knees.
Keep a stiff upper lip!
Tip #4 When choosing tags, select words that describe the subject matter, and also the type of verse (lyrical, romantic, humorous, etc).
Tip #5 You may use as many pseudonyms as you want, but you may like to group jingles appropriately under particular pseudonyms.
