Place value - Hundreds - Planning

In Year 3's introduction to place value, Lesson 7 is dedicated to understanding the concept of hundreds. This lesson serves as a foundation for children to grasp the idea that ten tens make a hundred and a hundred ones make one hundred. The resources provided for this lesson include Base 10 materials, bundles of 10 straws, place value charts, worksheets, and a presentation. Key vocabulary terms such as 'place value', 'digit', 'numeral', 'Base 10', 'hundred', 'tens', and 'ones' are emphasised. Children begin by completing 'fluent in four' questions, which act as a starter to refresh their knowledge of tens before moving on to the concept of hundreds.

The lesson unfolds through a series of practical activities. In Activity 1, children use various representations like base 10 blocks, straws, and place value counters to consolidate their understanding of tens and their relationship to one hundred. They engage in counting exercises, both up and down in tens, and use stem sentences to reinforce their learning. Activity 2 delves deeper into hundreds, challenging children to represent numbers using Base 10 and understand what each digit represents. They also explore the concept of hundreds through questions about grouping objects into hundreds. In Activity 3, counting in hundreds using a number track helps students identify patterns and changes in the sequence of hundreds. The lesson aims to correct common misconceptions, such as unitising and the significance of a digit's place value. The plenary includes a 'Give me five' reflection where children identify what they've learned, the skills they've used, any challenges faced, and the key takeaways from the lesson. Differentiated outcomes cater to varying levels of understanding, from working towards the expected level to achieving greater depth in their knowledge of hundreds.
