Statistics - Line graph problems - Planning

In the Year 6 summer term statistics lesson, students are tasked with solving problems using line graphs. This lesson builds on their previous understanding of how to read, interpret, and draw line graphs. The focus is on accurately reading information from scales and handling graphs that present more than one set of data. Key vocabulary such as 'graph', 'line graph', 'data', 'x-axis', 'y-axis', 'reading data', 'interpreting data', 'scales', and 'intervals' are emphasised. Students begin with a starter activity that includes fluency questions to recap their existing knowledge. The class teaching input involves modelling how to analyse questions and extract data from a line graph, using examples from learning slides.

During the lesson, students engage in a series of activities aimed at deepening their understanding of line graphs. The first activity presents a problem involving television viewership at different times, prompting students to analyse and discuss differences in data. The second activity compares two sets of data on a line graph, representing two families' journeys, leading to discussion about the representation and clarity of the information. Reasoning tasks challenge students to label axes correctly and compare different journeys. The plenary involves key questions that encourage students to think critically about the scales and organisation of the data. The lesson concludes with a reflective 'Give me five' activity, where students consider what they have learned, the skills they have used, and what they found challenging. Differentiated expectations are set for students working towards expected levels and those achieving greater depth in their understanding, with a focus on how they interpret information from graphs with varying degrees of marks on the axes.
