An $18,500 contribution from PG&E will help Manteca Unified put high-tech computer tablets in the hands of some of its students.The donation was made Jan. 12 and is part of a longstanding partnership between PG&E and Manteca Unified School District, which serves 23,000 students in Manteca, Stockton, Lathrop and the township of French Camp.In all, $21,000 was given to Manteca Unified, the bulk of the funds earmarked for the computer tablets and the remaining $2,500 to help fund the district’s Planet Party Day event. The Planet Party day festivities, which PG&E has supported in the past, mixes fun and learning to teach sixth-graders about the environment.“I’m very excited,” said Victoria Brunn, Manteca Unified’s coordinator of sustainability and energy education. She said the district – depending on what tablets are purchased – hopes to buy enough for one or two classrooms.
