These reactions to the performance are a testament to the blast the children had. I don't know that I've seen such an enthusiastic response to a field trip outing in all my years of teaching. Keep on doing what you do so perfectly -- what a gift!

Thank you SO much for the Multiply by Music CD! I knew it would help my 3rd Graders learn their multiplication facts, but I had NO idea how much they would love it! They don't even realize they are learning! After using the CD to learn multiplication facts I have at least one student ask me when we're done if we're going to do math that day! This CD has certainly made my life easier! I have used it during one of my observations and my principal loved it too! Thank you for making a CD for the older crowd!!!

I just wanted to tell you how outstanding you are! I have been a teacher for 6 years and you have been playing out of my radio for the past 3 years. i don't know how I taught without you! I am currently a Pre-K teacher and people are always coming into my class and are amazed that my students can say the months of the year and the letter sounds. I always tell them I could not have done it without your music. I am not sure how much money you make, but you should be making just as much as Garth Brooks, because you are amazing and you teach children wihout even being there.

Thank again, Emily O'Brien

I just came from your presentation at the Hilton in Columbus, OH. It was fabulous! My students LOVE your music and have learned SO much. The "Counting by 5's" is one of their favorites. They learned the vowels and letter sounds easily from "Shake, Rattle n' Read". Thanks so much and thank you for helping me make learning fun!

Hi there Jack, just wanted to say think you for what you do. You are a blessing to kids as well as teachers. You prove that learning can be fun and it should be. Was at the convention center today in Tampa and hade a lot of fun! My kids and I have been a fan of yours for some time now. Once again, keep up the great work and thanks!

WE LOVE YOU MR. HARTMANN. I use your Hop 2 It CD in my Pre-K class!!! It has been wonderful. Now the three year old and two year old class are learning letters and sounds because of the fun they hear us having in the Pre-K class. Keep making the songs. you are truly gifted.
