Swing with Slide

The kids' swings and slides are a popular outdoor entertainment unit that is ideal for children between two and 12 years. These units can be placed indoors or outdoors in the backyard or garden. These are designed to be lightweight with a sturdy base and can be folded for compact storage based on the brand and style.I would refer to that as "playground equipment". In regards to your example sentences: For the first, I would just specify what specific piece of equipment ("Our children are playing on the slide") or just speak in a generalization ("Our children are playing at the playground").With a slide show or slide presentation, a slide is a single page or image shown in a slideshow. For example, when watching a picture slideshow of ten pictures, a single picture is considered a slide. With a presentation or program like Microsoft PowerPoint, a slide is one page of text, images, or animations.
