The ideal is that a city can pay for all the educational needs of its schools — books, art supplies and technology, as well as the cost of educational field trips. When a school makes its fundraising this much fun, though, it lessens the disappointment.

The Cambridgeport School’s annual Spring Fling Silent Auction and Talent Show is Saturday, and this year boasts a staggering array of offerings on which people can bid. The entry fee of $5 (or $20 for a family of four or more) includes free Upper Crust pizza and cookies from Harvest Co-op and Whole Foods.

Organizers look at the event as an opportunity rather than a necessity.

“To show support for the local economy and laud its sources of pride, auction organizers tapped longtime beloved businesses — as well as the city’s wellspring of innovative companies — for their products and services,” organizers said. “They also sought out talent from within the school’s community.”

Here’s how organizers describe the collection:

Auction items range from food to fitness to fun. They include gift cards from Summer Shack, Atomic Bean Cafe and East Coast Grill; products such as Taza Chocolate and IdeaPaint dry-erase paint; tickets for the Red Sox, ImprovBoston, Central Square Theater and the ART; classes from Prana Power Yoga and the Gymnastic Academy of Boston; plus fitness club memberships, toys from StellaBella, Duck Tour passes and a kids’ bike helmet from Broadway Bicycle School. Art pieces include a painting by Cambridgeport grandparent Irvin Nahan, who appears in the new documentary The Art of the Steal about the Barnes Foundation collection of art near Philadelphia.

IdeaPaint, Harmonix, Tupelo restaurant and José Mateo Ballet Theatre are among the local businesses donating items, but classroom creations will also be sold, along with student-designed magnets for a Houses-for-Haiti fundraiser benefiting Partners in Health. Gardening enthusiasts can order flower bulbs, plants and upside-down tomato planters at the Flower Power Fundraising table.

The Spring Fling Silent Auction and Talent Show is Saturday from 5 to 7:30 p.m. in the Cambridgeport School gymnasium, 89 Elm St. Open to the general public, this fun family event is sponsored by the Cambridgeport Parent Teacher Organization.
