Addition and subtraction - Related facts 2 - Worksheet

The "Related Facts" worksheets are a set of educational resources aimed at enhancing the fluency and precision of Year 6 students in addition and subtraction. These materials align with the National Curriculum objective to recall and use addition and subtraction facts to 20 fluently and derive related facts up to 100. To support learning, differentiated worksheets and teaching slides are provided, along with specific vocabulary such as "related facts", "similar", "digits", "tens", "ones", and "part-whole model". These terms are critical for students to accurately discuss and understand the concepts being taught.

Students are encouraged to explore related facts through a variety of exercises that include completing part-whole models and solving number sentences. The tasks are designed to help students notice patterns and relationships between numbers, particularly focusing on the concepts of tens and ones to aid comprehension. For example, children might be asked to complete part-whole models with missing numbers or derive related facts from given calculations, such as understanding that if 9 equals 10 minus 1, then 90 equals 100 minus 10. The worksheets cater to different levels of ability, ranging from those working towards the expected level to those capable of greater depth, with reasoning and problem-solving tasks that extend beyond 100, challenging students to apply their knowledge to larger numbers.
