Place value within 100 - One more one less - Planning

In the second week of the Summer term, Year 1 students focus on understanding the concept of 'One more One less' within the place value to 100. The lesson starts with a small step starter, where children recap previous learning and answer questions to refresh their understanding. The class then moves on to practical activities where children work in pairs, using concrete objects and visual aids such as number lines and hundred squares. They are tasked with finding one more and one less than a given number, first by physically manipulating objects and then by using the more abstract visual methods. This hands-on approach helps them grasp the concept of incrementing and decrementing numbers within the context of place value.

Throughout the lesson, children use key vocabulary such as 'most', 'least', and terms that compare sizes and amounts. They engage in independent learning through differentiated worksheets and consolidate their learning in a plenary session. The class is encouraged to articulate their understanding with phrases like "One more you count up, one less you count back." Key questions prompt students to think about the changes in tens and ones when adding or subtracting one, and common misconceptions are addressed to ensure a clear understanding. The lesson concludes with a reflective 'Give me five' activity, where students assess what they've learned and identify the resources or support that helped them. Differentiation is provided for children working towards the expected level, at the expected level, and at greater depth, ensuring that all students can progress and build confidence in their place value skills.
