Kate MiddletonandPrince Williamare capping off the coronation weekend on a charitable note.

On Monday, the Prince and Princess of Wales visited the 3rd Upton Scout Group in Slough — a cause close to Kate, who is the joint President of the Scout Association. Also joining in the fun were their children: Prince George, 9, Princess Charlotte, 8, andPrince Louis, 5 (in his first official royal engagement!).

Kate was a Brownie as a young girl alongside her sister,Pippa, who attended King Charles' coronation on Saturday with their brother and parents. The royal became a patron of the organization in 2012, helping to raise volunteer numbers, and has been aregular visitorto their troops since. Both Princess Kate, 41, andPrince William, 40, wore Scouting scarves around the their necks during the engagement.

The family then took turns at archery. Kate looked like an expert as she took aim — after all, she’s tried it before. During a2016 visit to Bhutan, the royal shot a bow and arrow (while in a skirt and heels, no less!).

But it wasPrincess Charlottewho hit a bullseye, says Matt Hyde, CEO of Scouts and co-founder of the Big Help Out.

Anne Edwards, an adult Scout helper, was in charge of the plants — and said, “Kate came straight over. She is interested in plants and asked me where they came from.”

Edwards adds that the Princess of Wales “was taking interest in what we were doing, but she was keeping an eye on the children, especially Louis. They are a lovely, very natural family, very easy to talk to. You don’t feel as they’re royal — there’s no bowing, we were just chatting to them.”

Though Charles became King immediately upon the death of his motherQueen Elizabethin September, his symbolic crowning significantly continued nearly a thousand years of royal tradition.

“Charles became King Charles the moment his mother died, but the coronation is to do with the job and being the monarch in the eyes of all the people,” royal historian Robert Lacey previously told PEOPLE.
