After studying John Kelliher's Elementary School 'Grades 3, 4 & 5 Maths – Handling Data - Ages 8-11' eBook your child should be confidently able to:

- process, represent and interpret data.

- solve problems involving data.

- interpret tables, lists and charts as used in everyday life; to be able to construct and interpret tables, frequency tables and grouped discrete data.

- represent and interpret discrete data using graphs and diagrams, including pictograms, bar charts and line graphs, then interpret a wider range of graphs and diagrams, using ICT where appropriate.

- know that mode is a measure of average and that range is a measure of spread, and to use both ideas to describe data sets.

- recognise the difference between discrete and continuous data as well as to be able to draw conclusions from statistics and graphs.

- recognise when information is presented in a misleading way; explore doubt and certainty and develop an understanding of probability through classroom situations.

- discuss events using a vocabulary that includes the words 'equally likely', 'fair', 'unfair', 'certain'.

As such it is fully aligned with the North American curriculum.
