Gather ten carpet tiles or squares of vinyl flooring. If your squares aren't the same color already, or if the color is dark, spray paint them all white first. Then use a stencil to paint numbers 0-9 on the squares in different bright colors.
Allow at least 24 hours for drying before playing with the tiles. You can arrange the tiles in a classic hopscotch pattern, as shown, and use them either indoors or out. A beanbag or a rock can be used as a marker. Read the full hopscotch rules here to refresh your memory!
Playing hopscotch, children will learn math skills like how to identify numbers and patterns. They'll learn gross motor skills like how to hop on one foot and how to balance while they pick up a beanbag. They'll also learn social-emotional skills like taking turns and following rules.
The numbered carpet tiles could be used for many other activities inside or outside as well. Use them for group times, and give each child a designated space to sit or stand. Make letter squares or shape squares, as well, for more variety, and allow children to make up their own games using the carpet tiles.
