Addition, Subtraction, Multiplication and Division - Primes to 100 - Worksheet

The worksheet titled "Primes to 100" is a comprehensive resource aimed at enhancing Year 6 students' understanding of prime numbers, common factors, and multiples. It is aligned with the National Curriculum objective to identify common factors, common multiples, and prime numbers. To facilitate this learning, differentiated worksheets and teaching slides are provided, catering to varying levels of ability. The vocabulary section introduces key terms such as prime numbers, prime factors, composite numbers, common factors, and common multiples, building upon the foundation laid in Year 5. The worksheet challenges students to list prime numbers within specific ranges, such as 10-20, 20-40, and 40-100, and to break down numbers into their prime factors using prime factor trees.

Students are further engaged through fluency, precision, reasoning, and problem-solving activities. For instance, they are asked to find prime numbers that add up to specific totals, such as two primes that sum to 24 or 44, and three primes that sum to 47. These exercises not only reinforce the concept of prime numbers but also develop arithmetic skills. Additionally, a reasoning task prompts students to shade multiples of 6 on a 100 square and observe patterns related to prime numbers, enhancing their analytical skills. The worksheet provides answers to facilitate self-assessment and ensure conceptual clarity. This structured approach allows students to work at different levels, from working towards the expected standard to achieving greater depth in their understanding of prime numbers and their properties.
