Year 4 Block C – Handling data and measures
The focuses of mathematics learning within this block are:
 Readings from scales
 Comparing impact of different scales
 Constructing tables, diagrams, tally charts, pictograms and bar charts
 Collection, organising, presenting and interpreting data to answer related questions
 Identifying further questions
 Explaining reasoning using text, diagrams and graphs
 Using standard metric units to estimate, measure and record measurements
The objectives for the block are listed in the table – the right hand column indicates how the objectives might be addressed in the units
Objectives 
Unit 1 
Unit 2 
Unit 3 
Suggest a line of enquiry and the strategy needed to follow it; collect, organise and interpret selected information to find answers 



Answer a question by identifying what data to collect; organise, present, analyse and interpret the data in tables, diagrams, tally charts, pictograms and bar charts, using ICT where appropriate 



Report solutions to puzzles and problems, giving explanations and reasoning orally and in writing, using diagrams and symbols 



Choose and use standard metric units and their abbreviations when estimating, measuring and recording length, weight and capacity; know the meaning of 'kilo', 'centi' and 'milli' and, where appropriate, use decimal notation to record measurements (e.g. 1.3 m or 0.6 kg) 



Interpret intervals and divisions on partially numbered scales and record readings accurately, where appropriate to the nearest tenth of a unit 



Compare the impact of representations where scales have intervals of differing step size
