Decimals - Round Decimals - Planning

In the Year 4 summer term, students focus on rounding decimals during their second week of learning about decimals. The lesson begins with a recap of the fundamental concept of rounding numbers up or down based on whether they are in the 0-4 or 5-9 range, using memorable rhymes to aid understanding. Students are introduced to the term 'integer' and use a simple number line to identify what comes before and after a given number, discussing patterns and increments. A practical activity involves using a metre stick or number line to annotate decimal numbers, allowing children to physically engage with the concept of rounding and understand the value of each increment.

The lesson progresses with an activity where students identify which numbers would round up, reinforcing the concept of 5-9 indicating a round up. Partner work encourages discussion and explanation about why certain numbers do not round up. Independent learning is facilitated through differentiated worksheets tailored to various levels of understanding, from working towards the expected standard to achieving greater depth. The key questions focus on identifying the whole numbers a decimal lies between and understanding which digits influence rounding decisions. The lesson concludes with a reflective 'Give me five' plenary, where students consider what they've learned, the skills they've used, and what they found challenging, ensuring they remember the key points of rounding decimal numbers to the nearest whole number.
