(0)
Change an improper fraction to a mixed number and recognize equivalent fractions. Recognize relationships between fractions and reduce a fraction to its simplest form Express simple fractions as percentages

#### Handling Data

(0)
Handling data (Organizing, categorizing and representing data) Answer a set of related questions by collecting, selecting and organizing relevant data; draw conclusions from their own and others’ data and identify further questions to ask. Draw and interpret frequency tables, pictograms and bar line charts, with the vertical axis labelled for example in twos, fives, tens, twenties or hundreds. Consider the effect of changing the scale on the vertical axis. Deduce new information from the existing information to solve problems Use ordered list and tables to help solve problems systematically Explain methods justifying reasons orally and in writing: make hypotheses and test them out.
