Third and fourth graders at Redwood Adventist Academy in Santa Rosa were expected to pull in more than $2,500 for the American Heart Association with their annual jump-a-thon Friday.

 Students got flat donations or per-jump pledges, according to teacher LouAnn Clemons, who has been hosting the jumpathon with her students for more than two decades.

 “The kids that are jumping a penny a jump are seriously doing some jumping,” she said of the three hour event.

 “It’s one of the things the kids look forward to every year. The kids won’t let me quit,” she said. “This one seemed to work pretty good so we  keep doing it.”

 The students will give their grand total to American Heart Association officials on Jan. 2.

 American Heart Association officials estimate that Clemons’s classes over the years have donated more than $80,000.
