Place Value within 50 - One more one less 2 - Planning

The Year 1 Spring curriculum on Place Value within 50 focuses on the concept of 'one more and one less'. The second week's lessons are designed to help children understand and identify the number that is one more or one less than a given number up to 50. To facilitate learning, a variety of resources are provided, including differentiated worksheets, teaching slides, ten frames, and number tracks. The key vocabulary for the lessons includes terms like 'before', 'after', 'tens', 'ones', 'digit', 'value', and 'represent'. Children are encouraged to use concrete equipment to build numbers, utilise number tracks, and refer to 1-50 grids to reinforce their understanding. Partner work is emphasised to promote discussion and the use of full sentences to explain reasoning.

The lesson's independent learning activities involve problem-solving and reasoning exercises where children draw representations of tens and ones to solve practical problems, such as determining how many sweets are left after one falls out of a bag. These activities are tailored to different levels of understanding, with sheets indicating where the numbers change in the ones or tens place. The lesson concludes with a reflective 'Give me five' plenary, where students evaluate what they've learned, the skills they've used, any difficulties they encountered, the resources that aided them, and what they need to remember from the lesson. The goal is to ensure that students grasp the concept of one more and one less and understand which digit changes when these calculations are made.
