Howard, a Chicago native and Valparaiso University graduate, spent some time visiting classrooms before being the special guest for an all-school assembly in the school gym.
After being introduced, he spoke about the importance of reading and the need to work hard to succeed in school and in life.
"Reading is something you're going to need forever," no matter what career path you follow, he told students. "I urge you to continue to work harder to be the best reader you can be, because it is going to help you.
"All these things I have been able to do started where you guys are — started in grade school," said Howard, who played briefly for the Indiana Pacers and has played for professional basketball teams in other countries, including last season in South Korea.
There will be tough times and sacrifices to make, but working really hard will help you achieve any goal you want to achieve, he said.
Then it was time to take to the court.
Cheered on by a pumped up crowd of students in pre-kindergarten through grade 5, Amstutz-Martin and Howard battled in a friendly game of P-I-G.
Amstutz-Martin, who already had invited two boy students to help her, then called up three teachers for the three-on-three game, with Rachel Merz and Adam Basinger playing on her team against Howard and the boys while Donna Satterthwaite served as referee.
Howard and the boys, who were the first team to make three baskets, got the "W." But everyone had fun.
