At a school assembly Tuesday morning, Christensen pulled off her hat and displayed her new purple hairdo, revealing that students had already reached a total of 3,832 points, exceeding the 2,500 goal roughly two months early.
“It blew me away that six weeks into the challenge, they reached the goal,” Christensen said.
The 520 kindergartners to fifth-graders at Bohn read books from the school library and then took computerized tests on comprehension and vocabulary.
Books are given an A.R. point score from 0.2 to 7.0 based on length and skill level.
Christensen said students had earned 1,110 A.R. points between August and December before winter break. She envisioned the challenge as a way to increase interest in reading.
“It gives them more exposure to reading,” Christensen said. “The more exposure benefits their comprehension and vocabulary skill and benefits the rest of their studies.”
Christensen said that in the weeks after she issued the challenge, she would find students using part of their recess and library periods to take A.R. tests about their books.
At the assembly, four students who had earned more than 100 points each rubbed another coat of purple dye into Christensen’s hair.
She plans to leave her hair purple for about a week.
