Lü case studies

Getting students engaged

“Main thing for me is getting students engaged, all my students engaged, even the ones that are really out of shape…” says Ed Brown, PE Teacher at the S.U.P.E.R Learning Center, a school specialized for special needs kids in Ohio. Lü allows teachers to go beyond the typical basketball nets and soccer goals.

We’re all working together!

“They want to be participating” says Ben Wells, PE Teacher at Bennett Ranch Elementary School in Colorado. Clearly Ben’s class would not be the same without their Lü. As one of his student says “we’re all working together and it’s amazing”!

Not a day without Lü

“The Lü transforms what a typical gym used to look like. I could not imagine a day when the Lü is not being use” says Mrs. Brittney Brown, principal at Willow Lake ES. Washington Township MSD equipped 8 of their Elementary schools with Lü.
