Multiplication and division - Make arrays - Planning

The Year 1 summer term lesson plan on multiplication and division introduces the concept of making arrays to solve one-step problems. The National Curriculum objectives are met by engaging students in activities that utilise concrete objects, pictorial representations, and arrays, with teacher support. The key vocabulary for this unit includes 'array', 'row', and 'column', essential terms for understanding the structure of arrays. The lesson begins with a recap of previous learning, prompting children to discuss what they know about arrays and the orientation of rows and columns. Practical activities include identifying arrays around the classroom, such as window panes, and using tens frames to explore the concept further. Students are encouraged to engage in paired discussions and use STEM sentences to articulate their understanding of arrays and their components.

During the lesson, children undertake hands-on tasks to build their own arrays, reinforcing their comprehension of rows and columns by constructing various array sizes and discussing the number of each. Key questions guide the learning process, ensuring students can define an array, differentiate between a row and a column, and recognise the number of rows or columns in a given array. The lesson addresses common misconceptions, such as the correct direction of rows and columns and the importance of having full rows and columns to form an array. The plenary includes a 'Give me five' reflection activity, where students evaluate what they've learned and identify any challenges they encountered. The lesson plan differentiates outcomes for children working towards expected levels and those achieving greater depth, with the latter being able to accurately construct and describe a variety of arrays using the correct terminology.
