Place value - Number line to 1000 - Planning

In Year 3, during the Autumn term's second week of Place Value, students engage with number lines to 1,000, building on their understanding of place value concepts. The lesson utilises a variety of resources such as place value counters, metre rules, measuring containers, and scales to provide a hands-on learning experience. The key vocabulary for this lesson includes 'place value', 'estimate', 'hundreds', 'tens', 'ones', and 'number line'. The lesson starts with a recap of counting forwards and backwards in multiples of 10 and 100, using a 0-1,000 number line to understand the sequence and ordinality of numbers. The main task involves estimating and positioning numbers on a number line, with some lines lacking intervals or start and end numbers, thus requiring the children to apply their knowledge to estimate the correct placement of numbers.

The lesson also incorporates practical activities, giving real-life context to the use of number lines by measuring various quantities such as capacity, length, and mass. This helps children understand the practical applications of their mathematical skills. Partner work and the use of manipulatives are encouraged to support the children's learning process, with an emphasis on explaining their reasoning behind placing numbers on the number line. The lesson concludes with a reflection on what has been learned, the skills used, and the challenges faced, ensuring the children are aware of their progress and areas for further development. Differentiated outcomes are provided to cater to varying levels of understanding, from working with multiples of 10 on number lines to estimating and creating their own start and end numbers on a number line according to given criteria.
