1 Understanding Fractions
I can give examples of where fractions, percentages and decimals are used in my everyday life. I can suggest why fractions or percentages or decimals have been used in a particular situation and choose a particular form to express an amount. I can read and write fractional notation e.g. 1/3 is said to be a third.

2 I can find a fraction of a quantity by dividing by the denominator.
I know the bottom part of a fraction is called the denominator and tells me how many shares there are. I know the top part of a fraction is called the numerator and tells me how many parts of the whole. I can find a fraction of a quantity by dividing by the denominator. I can describe what fraction remains or is needed to create a whole.

3 I can write the % symbol and explain that percent means “out of 100”.
I can find a fraction of a quantity by dividing by the denominator then multiplying by the numerator and can use this knowledge to solve problems in everyday contexts. I can write the % symbol and explain that percent means “out of 100”. I know that a percentage is a fraction with a denominator of 100. I can find a fraction of a quantity by dividing by the denominator then multiplying by the numerator to solve problems.

4 I can order the most commonly used fractions.
I recognise a percentage as a fraction, can calculate simple percentages of a quantity and use this knowledge to solve problems. I can order the most commonly used fractions. I can compare fractions relative to a particular whole e.g. one quarter of a pizza is less that half of it. I can compare simple percentages in real life situations.

5 I can convert fractions to percentages for comparison.
I know that a percentage is a way of describing a fraction where all the denominators have been made 100 to make comparison easier. I can convert fractions to percentages for comparison. I can visualise some fractions that to help me order and compare. e.g. ¼ is less than 3/8 because I can see ¼ is the same as 2/8. I can count in fractional amounts e.g. tenths, fifths, quarters, thirds.

6 I can use my knowledge of decimal place value to help match common fractions with decimal fractions.
I can use diagrams or grid paper to investigate how decimals are formed from fractions. I can show my understanding of simple fraction and decimal relationships through discussion or matching activities. I know that a percentage is a way of describing a fraction, where all the denominators have been made 100 to make comparison easier.

7 I can write any fraction as a decimal by using a calculator.
I can calculate the complement of a given percentage e.g. if 47% of a class are boys, what percentage are girls? I can express a percentage as a fraction with a denominator or 100, then simplify to find a common fraction. I can use my knowledge of decimal place value to help convert common fractions into decimal fractions. e.g. 4/5 = 6/10 = 0.6. I can write any fraction as a decimal by using a calculator.

8 I can use the term equivalent fraction.
I can use the term recurring to describe a decimal fraction with no finite answer. I can use the term equivalent fraction. I can share an object or collection in different ways to create equivalent statements. I can multiply or divide to create equivalent fractions.

9 I can simplify fractions and express them in their simplest form.
I know that simplifying a fraction means having the smallest possible denominator. I can use my knowledge of fractional equivalences to simplify e.g. 2/4 can be simplified to ½. I can simplify fractions and express them in their simplest form. I can divide to help find equivalent fractions.

10 I can draw or visualise a diagram to compare two fractions.
I can visualise some fractions that to help me order and compare. e.g. ¼ is less than 3/8 because I can see ¼ is the same as 2/8. I can draw or visualise a diagram to compare two fractions.
