The Academy Award-winner, 51, shares kids Violet, 18, Fin, 15, and Samuel, 12, with his ex Jennifer Garner.
Fin and Samuel were spotted at the park on June 13, as the 15-year-old Fin sported a green helmet and knee pads for the shredding session.
The teen – formerly known as Seraphina Rose – was practicing several skateboarding tricks including ollies and riding along a ramp.
Fin, who came out as non-binary in April, wore white sneakers with mix-matched socks – one blue and one white – as well as tan cargo shorts and a striped navy long sleeve with a green shirt underneath.

Affleck has been living in a $100,000 per month rental in Brentwood to be closer to his children, while Lopez, who shares 16-year-old twins Emme and Max from prior marriage to Marc Anthony, feels the 12-bedroom house they put on the market is simply ‘way too big for her.’
After few and sparse public outings together in recent months, Lopez further fueled the speculation when she announced that she would be canceling her tour to focus on her family.
Sources told DailyMail.com the pop star has reached her wit’s end with her ‘grumpy’ husband and no longer feels that she can do any ‘more’ to save the relationship.
‘Jenny has had enough and she really tried but she can do no more, it’s not getting any better, it’s worse,’ a music industry said.
While their marriage seems to be on the rocks, the couple has continued to show support for each others children.
On Father’s Day, the Jenny From The Block songstress shared a snap of Ben from his 2001 action film Pearl Harbor to her Instagram Stories as she praised him on the special day.
‘Our hero,’ she wrote along with a white heart emoji. ‘Happy Father’s Day,’ she added.
On June 14, while the Oscar winner was showing off his new Brentwood rental home to his mother, Lopez met up with his daughter Violet for lunch.

DailyMail.com previously reported that Affleck has been drinking alcohol again amid his tense situation with Jennifer.
Speaking exclusively to DailyMail.com, friends say the actor – who has battled alcoholism and a gambling addiction for decades – is suffering ‘acute sadness’ as his marriage collapses.
They claim Affleck is either ‘at risk’ of slipping off the wagon, or is already back on the booze.
