Addition and subtraction - Add three one-digit numbers - Worksheet

The educational resource from masterthecurriculum.co.uk provides a comprehensive worksheet for Year 6 students to practice addition and subtraction by adding three one-digit numbers. The National Curriculum objective for this lesson is to enable students to add and subtract numbers using concrete objects, pictorial representations, and mental strategies. To facilitate learning, the worksheet includes differentiated sheets, teaching slides, ten frames, coloured counters, and colouring pencils. The key vocabulary for this lesson includes terms such as addition, subtraction, number bonds, efficient, and commutative.

Students are encouraged to apply their understanding of commutativity to find the most efficient ways to add three one-digit numbers, particularly by identifying number bonds to 10. The worksheet guides them through using ten frames and counters to visualise and compare sums, while also encouraging different methods to find number bonds. Key questions prompt students to consider the order of numbers in calculations and the impact on efficiency. The resource includes a series of number sentences for students to compare using inequality signs and to find number bonds using alternative additions. Additionally, the Reasoning & Problem Solving section challenges students to investigate patterns when adding consecutive one-digit numbers and to explore the outcomes of adding even and odd numbers together. This section aims to deepen students' understanding of number relationships and arithmetic strategies.
