Place value - Tens and ones - Planning

In a Year 2 lesson focused on place value, specifically the concept of tens and ones, children explore part whole models as a means to understand and partition numbers. Utilising a variety of resources such as straws, part whole models, Base 10 equipment, worksheets, and a presentation, the lesson aims to solidify the children's grasp of what each digit in a two-digit number represents. The lesson begins with a recap of previous learning, followed by hands-on activities where children use straws to represent tens and ones, reinforcing their understanding through verbalisation and the use of stem sentences. As the lesson progresses, numerals are introduced and children are encouraged to recognise the value of each digit, using phrases like "The ___ represents ___ tens: it has a value of ___" to articulate their findings.

Practical activities involve partner work where children use dice to create numbers, then partition these into tens and ones using part whole models. They are supported by stem sentences to guide their understanding. The lesson also includes reasoning activities that deepen their comprehension, allowing children to partition numbers in various ways and discuss different strategies. Key questions prompt the children to think about the parts and wholes they are working with, and how to determine missing parts. The lesson addresses common misconceptions such as mixing up tens and ones during partitioning. The 'Give me five' plenary encourages self-reflection on the skills learned, difficulties encountered, and the importance of remembering the lesson's content. Differentiated outcomes cater to varying levels of understanding, from working towards expectations to achieving greater depth, with activities ranging from consolidating digit meanings to partitioning numbers in multiple ways.
