Statistics - Block diagrams - Worksheet

The educational resource provided offers a series of activities to help Year 2 students master the skill of creating and interpreting tally charts. The exercises are designed to support fluency and precision in data handling, starting with an introduction to making tally charts. Students use whiteboards, pens, differentiated sheets, and teaching slides to learn how to represent votes and counts using tallies. Vocabulary such as 'vote', 'tally', 'strike-through', 'tally chart', 'count', 'number', 'total', 'most', 'common', 'fewest', 'altogether', and 'difference' is introduced to aid understanding. The activities require students to complete tally charts, with initial guidance provided through examples, progressing to more independent tasks where they create their own tally charts to determine the class's favourite fruit, for instance.

In addition to the fluency exercises, the resource includes reasoning and problem-solving activities that challenge students to interpret and construct simple pictograms, tally charts, block diagrams, and tables. Through these exercises, students are encouraged to ask and answer questions about the data they collect and represent, such as identifying which items have the most or fewest votes, calculating totals, and understanding the difference in quantities. These activities cater to different levels of ability, with tasks tailored for those working towards, working within, and working at greater depth. This structured approach helps students to develop a comprehensive understanding of tally charts and their practical applications in categorising and comparing data.
