Place Value within 20 - Order numbers - Planning

The second week of Year 1 Autumn term maths planning introduces children to the concept of ordering numbers within 20. The lesson, titled "Order numbers (1)," is designed to reinforce the understanding of place value by focusing on the tens and ones in numbers. The class begins with a starter activity that prompts students to recall previous lessons and then moves on to a hands-on approach using a variety of concrete resources such as base 10 blocks, counters, and number frames to represent numbers. This tactile experience is complemented by differentiated worksheets and teaching slides that guide the children through the process of ordering numbers from the least to the greatest and vice versa. The key vocabulary for this lesson includes terms such as 'order', 'tens', 'ones', 'most', 'least', 'greatest', 'smallest', 'compare', and 'strategy', with vocabulary cards and definitions available to support learning.

During the lesson, children engage in a variety of activities to deepen their understanding of number order. They start by comparing numbers with the same number of tens and learn to order them by looking at the ones. The lesson then connects ordering numbers to real-life scenarios and introduces ordinal numbers, prompting children to discuss who scored the most hoops or who came third in a game, for example. In group work, children use large numeral cards to identify and order numbers, and through partner work, they articulate their reasoning in full sentences. The lesson aims to address common misconceptions, such as mistaking the greater of two numbers by only considering the ones digit, by emphasizing the importance of tens in determining value. The plenary session allows children to reflect on the skills they've used, the strategies they've developed, and what they need to remember for future lessons. Differentiated activities are provided to cater to varying levels of understanding, from working towards expected standards to achieving greater depth, ensuring that each child is supported in mastering the skill of ordering numbers.
