Decimals - Adding and Subtracting Wholes and Decimals - Planning

In a comprehensive lesson plan tailored for Year 5 students during the summer term, the week's focus is on mastering the addition and subtraction of whole numbers and decimals. The curriculum objectives aim to deepen the pupils' understanding of decimal equivalents for tenths and hundredths, as well as the effects of dividing numbers by 10 or 100. Students will also tackle measure and money problems involving decimals and learn to convert between different units of measurement. Essential vocabulary such as 'decimal number', 'place value grid', and 'column method' are introduced to facilitate the learning process. The lesson includes a variety of resources like counters, place value charts, and bar models, alongside worksheets and presentations to support both teaching and independent learning.

The lesson begins with a review of previous knowledge, where students are encouraged to define and provide examples of whole numbers through partner discussions. They then move on to activities which revisit column subtraction and addition, with emphasis on the correct alignment of calculations and the use of place holders. Pupils are given practical tasks to demonstrate their understanding using counters and place value charts. As they progress, they are challenged to find the most efficient methods for solving addition and subtraction problems, with opportunities to explore different strategies such as bar modelling. The lesson concludes with a reflection on the skills learned and the methods used, ensuring that students can identify common misconceptions and reinforce their understanding of working with decimals. Differentiated worksheets cater to varying levels of proficiency, from those working towards the expected level to those capable of greater depth analysis.
