I've mentioned God's Kid Worship CD's before, but they keep coming out with more and more cool resources for kids!
Check out the description of the Big Box of Countdowns below:
High Energy Countdowns - 5 minutes long, high-energy and filled with fun! The infectious music tracks, eye-catching backgrounds and animated graphics will get any group of kids ready for what's coming next. Most feature animated characters, complete with hilarious and attention-getting comments! Characters pop on-screen and speak at 4:00, 3:00, 2:00, 1:00 and the final 30 seconds, bringing everybody's attention up front.
Calm Countdowns - 5 minutes long, low-energy video countdowns filled with warm, images and calming music. Use these as a calm way to focus and prepare for an event; or as a timer for any quiet activity, such as study, reading, or simply rest & reflection.
