Hi, (for england) the EYFS requires, supports and promotes the theory of learning through play, in balance with learning through focussed activities with an adult - these can be two strategies that your setting uses to share ideas and teach maths, and that enables children to discover and explore maths for themselves.
Strategies can also involve open ended tasks that encourage exploration, and multi sensory activities.
It can be helpful to remember that math isn't just numbers, addition & subtraction. It involves positional, directional and descriptive language - size, shape, pattern, space, time, weight, volume, capacity, measuring, matching, sorting, data representation, estimation, technology and problem solving.
