What's Inside?

This 9-week unit is meticulously planned to help you deliver exceptional Maths lessons with confidence. You will find:

• 9 Weeks of Engaging Lesson Plans: Guide your students through a journey of discovery, from becoming "Decimal Champions", hosting a "Mixed Numeral Pizza Party", creating "100-Grid Art", hunting for factors with "Factor Rainbows & Arrays", "Coding for Factors" and proudly presenting their final "Architect Showcase" project.

• Play-Based & Experiential Learning: Foster genuine understanding with interactive and creative activities that make number concepts memorable and impactful. Imagine your students building factor arrays with Lego or counters, constructing their own "Fraction Wall", designing 100-Grid pixel art, using block-coding (Scratch) to build a divisibility checker and calculating discounts in a "Best Buy Challenge".
• Built-in Assessment & Differentiation: Effortlessly monitor student progress through natural observation opportunities and exit tickets embedded in each activity. Every lesson includes clear support and extension tasks to cater to all learners in your classroom.
• Early Career Connections: Expose students to potential future pathways by weaving career education into every lesson. Connect activities to the work of a Pharmacist, Chef or Baker, Data Scientist, Accountant, Cryptographer (Code Breaker) or a Software Developer.
