Chuck Serventi, a 5th grade teacher, struggled with effectively teaching math to a diverse group of students within the limited classroom time. He discovered the digital tool helloWorld, which allowed him to record and archive lessons for students to review anytime. This helped increase instruction time and engage students. Using helloWorld, Chuck saw test scores rise by 30-50% for many students. It also improved parent communication by allowing them to view lessons. As a result of his success using technology, Chuck was named Teacher of the Year in Arizona.
