Sum Building Pebbles - Set of 50

Spark a love of numbers with these tactile number pebbles, designed to engage children's natural curiosity to sort, collect and explore. Cast from a durable stone and resin blend, the pebbles are suitable for use indoors and outdoors, making them ideal for sensory play, loose parts learning and mathematical investigations in sand, water and outdoor environments.

Each pebble is engraved and colour-filled with a numeral or mathematical symbol, providing a clear and lasting visual representation for early maths activities. Children can use the pebbles to explore number recognition, counting, sequencing, simple equations and problem-solving through hands-on learning.

This set includes 50 pebbles featuring two of each number from 0–20, two each of the +, – and = symbols, and one each of the × and ÷ symbols.

Pebble size: 30–45mm.
