Gifted and Talented Teacher creates high-quality teaching resources and printable teacher resources designed to support calm, organised, and engaging learning environments. From curriculum-aligned teaching tools to functional classroom decor, our resources are classroom-ready and designed to save teachers time.

Teach students to find percentages of quantities and calculate discounts with this complete teaching bundle. Students connect percentages with hundredths and decimals, find 10% first and build other percentages from it, calculate discounts and sale prices, and check with a decimal and a calculator.

Combining a lesson plan, a 46-slide editable teacher presentation, three differentiated student activities, an exit ticket with interpretation guide and a hands-on sale day catalogue, this curriculum-aligned bundle provides everything you need to teach the lesson from start to finish.

Built around the I Do, We Do, You Do model, students move from explicit teacher modelling to guided practice and independent application. They use bar models and hundred grids, find 15% and 45% by combining 10% and 5%, spot the error in a discount, decide which deal is better, solve mystery discounts and explain their strategy using mathematical language.
