Place value within 10 - Ordinal numbers - Planning

In Year 1 maths planning, a lesson on ordinal numbers is designed to help children understand number positions within a sequence. The lesson is part of the Autumn term's focus on place value within 10 and is scheduled for Week 4. The key vocabulary introduced includes terms such as 'order', 'next', 'before', 'ordinal', and specific ordinal numbers like 'fifth'. To support learning, a variety of resources are provided, including differentiated worksheets, teaching slides, and word cards. Children are encouraged to explore the spelling of ordinal numbers and the endings such as '-st', '-nd', '-rd', and '-th'. The lesson starts with a recap of previous learning to reinforce the concept of numbers as positional and builds on earlier lessons about ordering numbers. Partner work is encouraged to foster discussion and the use of full sentences in mathematical contexts.

During the class, children engage in practical activities that involve using ordinal numbers to describe the position of coloured cubes in a tower and identifying objects based on their ordinal position. They are also introduced to the written formats of ordinal numbers, such as '5th' and 'fifth'. Reasoning and problem-solving exercises further develop their understanding, asking them to work out the position of shapes and the order of objects or people in a line. The lesson concludes with reflection on what they've learned and a review of the skills used, such as counting, along with a promise to remember key concepts. Worksheets are tailored to different levels of understanding, from 'Working Towards' to 'Greater Depth', challenging children to identify colours of beads based on their ordinal number and to determine the position of coloured beads within a sequence.
