Jane Martin makes a joyful and inclusive statement in her anthem, 'Make Music!' The scale passages will serve as good music reading examples; extract those and introduce them in your warm-up (measures 32 through 35, 37 through 39, and 59 through 62). The parallel thirds will provide the opportunity for working on tuning. The closing section would make an interesting Call to Worship or a fanfare to an opening hymn of praise.
