The Numicon 100 Square Baseboard from Oxford is a visual maths resource built to strengthen children's understanding of number and place value. Its clear 100 square grid gives students a structured, hands-on way to explore counting, sequencing, and the relationships between numbers, making it a core piece of the wider Numicon teaching system. The bold colours and large numerals are designed to hold young learners' attention while presenting mathematical concepts in a format that is easy to read and follow. This hundred square grid supports a wide range of classroom and home learning activities, from basic counting and skip counting to more advanced work with addition, subtraction, and place value patterns. Teachers and parents can use it to demonstrate how numbers build in tens and units, helping children move from concrete visual representations to abstract number sense. As a maths resource for children, it also lends itself well to group activities, allowing several students to work through problems together on a shared grid, reinforcing learning through discussion and repetition. This place value teaching tool suits primary school classrooms, tutors, and parents looking to support numeracy development at home. It works well alongside other Numicon shapes and baseboards, extending its use across different stages of maths learning. For anyone seeking a dependable, visually engaging way to teach number structure and build confidence with the hundred square grid, this baseboard offers a practical, long-term addition to any maths teaching toolkit.
