Bonnie Winder's class is whipping up this "Recipe for Fun" every morning this week. The youngsters, in kindergarten through second grade, created puppets based on the children's book "The Hungry Caterpillar" in preparation for an end-of-the-week puppet show.

Winder's class at Bennion Elementary School has only one recipe in a growing "menu" of the Salt Lake School District - the enrichment and educational classes offered outside of the regular school day.

Tricia Caldwell, community education manager, thinks the enrichment classes are perhaps the district's best- kept secret. Without an adequate publicity budget, the program, now in its fourth year, has grown mainly through word of mouth.

"Usually I get a call from someone, a PTA president or principal, who says, `I saw your flier, and we want to do it, too.' "

Classes are mainly offered after school for one hour in six-week blocks. Bonneville, Dilworth, Emerson, Hawthorne, Uintah and Washington elementary schools participate in the after-school classes.

And one school, Bennion, offers them during a break in the school's year-round schedule.

Each school has between four and six enrichment classes. A modest fee, ranging from $1.50 to $22 per class, is charged to pay the teacher's salary and supplies.

Among the fall offerings are classes in fiber art, pottery, creative writing, drama, creative dance, spiders and insects, swimming, basketball, basic art and watercolor and clowning.

To help with the classes, the district has enlisted co-sponsors. The Utah Museum of Natural History often helps with science classes, as it will this fall with spiders and insects. Ririe-Woodbury Dance Company is involved with the dance classes, while Salt Lake County Recreation co-sponsors the basketball clinics.

Fall enrichment classes begin Oct. 1. For registration information or information about establishing an after-school program, call Caldwell at 481-4804.
