Data Detectives brings together tally charts, pictograms and block diagrams for Year 2 maths. Pupils complete a minibeast tally from a hunt list, read a favourite fruits pictogram to find the most popular fruit and compare totals, then answer questions about a pets block diagram. Every section has answers. Covers three England National Curriculum statistics objectives.
Statistics
“Interpret and construct simple pictograms, tally charts, block diagrams and simple tables”
One section per chart type, constructing the tally and reading the rest.
Statistics
“Ask and answer simple questions by counting the number of objects in each category and sorting the categories by quantity”
The pictogram and block diagram questions are all category counts.

How-many-more and altogether questions run through every section.
