Place Value within 20 - Order groups of objects - Planning

In Year 1 maths, students are introduced to the concept of ordering groups of objects within the number range of 20. This lesson builds on their existing knowledge of sequencing objects up to 10, with a focus on reinforcing their understanding of numbers below 10 as well. The class is provided with a variety of resources, including differentiated worksheets, teaching slides, and concrete resources like base 10 blocks, counters, and cubes. Key vocabulary such as 'order', 'groups', 'numbers', 'methods', 'largest', and 'smallest' are emphasised, with vocabulary cards and definitions available to support learning. The lesson begins with a starter activity where children practise spelling teen number words and complete 'fluent in four' questions to recap previous learning.

During the class, children engage in partner work to encourage discussion and use of full sentences to explain their reasoning. The teaching input includes activities where students identify the smallest and largest numbers and determine the sequence of other groups. They use cubes to represent numbers, discussing the concept of tens and ones, and compare quantities like 19 and 14. Problem-solving activities involve arranging fruit in baskets, with a focus on efficient methods, and ordering objects while addressing misconceptions like assuming a group with a visible ten has the most items. The lesson concludes with a reflection on the skills used, such as counting and ordering, and what was learned about sequencing groups of objects. Differentiated worksheets cater to varying levels of understanding, from working towards the expected level to greater depth, with tasks ranging from counting simple pictures to ordering mixed images representing numerical values.
