This is turning into a popular feature here on Whoa, Momma! So, back by popular demand, is our weekly look at what's free and cheap to do with your kids:

See if the kids can bring home dinner at the Family Fishing Fun Day at Largo’s Walsingham Park on Saturday. It’s free for kids 14 and younger (with adult). Poles and bait provided, but you can bring your own fishing gear, too. There will be prizes for largest and smallest fish, first fish, multiple catches and more. It runs 8 to 11 a.m. at the park at 12615 102nd Ave. N, Largo.

The Beach Theatre continues its free kids matinees on Saturday mornings at 10 a.m., at 315 Corey Avenue, St. Pete Beach. This week it's "The Return of the Pink Panther" starring Peter Sellers.

Join the Rays at the Campbell Park Recreation Center, 501 14th St. S, St. Petersburg, on Saturday from 10 a.m. to 1 p.m. for the Rays Summer Block Party.  Festivities begin on Oliver Field with the Mount Zion Missionary Baptist Church Marching Drum line kicking things off followed by games, kickball, wiffleball and music by 95.7 The Beat. There's free food, and an opportunity to meet a Rays players and get autographs. You can also register to vote and teach your kids about it in the KidsVote booth.

   The kids won't be as happy about this one because it means that the new school year is getting closer: The All About Kids Back to School Bash will feature exhibits, entertainment by Radio Disney and Nickelodeon, appearances by Dora the Explorer, SpongeBob SquarePants and others, a character parade (at the start of each day), craft activities, batting with the Tampa Bay Rays, bicycle rodeo, Baby Wonder Zone for babies and toddlers up to age 2 and expectant parents, Treat Street Snack Zone and more. The bash is 10 a.m.-4 p.m. Saturday and noon-4 p.m. Sunday at the Tampa Convention Center, 333 S Franklin St. Admission is $9 for adults (get a $1 off coupon at Publix or click here), ages 12 and younger free (limit 3 kids per paying adult).

For all of those who thought the Lowry Park Zoo was a little too crowded on its $5 Zoo Day (another one is coming up Sept. 7), the zoo brings you Nite Zoo. The park stays open late with free rides after 5 p.m., including Gator Falls log flume ride. Nite Zoo is from 5-8:30 p.m. at the zoo, 1101 W Sligh Ave., Tampa. Tickets are $18.95, $17.95 seniors, $14.50 ages 3-11 and free for Zoo Passholders.

If you have a favorite little princess, she may love Rodgers and Hammerstein’s Cinderella performed by the Summer Broadway Series camp. Shows are 7 p.m. Friday; 3 and 7 p.m. Saturday; and 3 p.m. Sunday at the Carrollwood Cultural Center, 4537 Lowell Road, Tampa. Tickets are $10. (813) 269-1310.

If your kids are fascinated by lightning, thunder and other weather phenomena, take them to "Flash! Bang! Boom! Discover our Amazing Weather!" from 10-11 a.m. Friday at the Brooker Creek Preserve Environmental Education Center, Tarpon Springs. Registration is required and admission is free.

And a wise reader hipped us to this coupon for a buy one get one free admission deal at the Clearwater Marine Aquarium, 249 Windward Passage in Clearwater. But act fast: It expires Thursday.

Now get out and have some fun!
