Understanding Number I can check adding and subtracting calculation by rounding whole numbers to the nearest 10, 100 and 1 000. I use knowledge of context to decide if an answer makes sense. I can use skills of estimation and rounding in a range of real life contexts.

I can sequence numbers to 100 thousand. I can use the pattern for saying numbers to 100 to read and write any whole number to 100 thousand. I can sequence numbers to 100 thousand. I can estimate the position of any whole number to 100 thousand on an empty number line. I can count forwards in multiples of 10s, 100s and 1000s from any whole number to 100 thousand.

I can investigate how to partition whole numbers in different ways. I can count backwards in multiples of 10s, 100s and 1000s from any whole number to 100 thousand. I can explain what each digit in any whole number (to at least 1000) means. I can use materials or diagrams to show how many 1000s, 100s, 10s and 1s in a number to 100 thousand. I can investigate how to partition whole numbers in different ways.

I know and can explain that zero is a place holder. I can compare different ways of partitioning the same number. I can use a number line to demonstrate different ways of counting on and back. I know and can explain that zero is a place holder. I can explain and show the effect of multiplying and dividing by 10 or 100 for an increasing range of whole numbers.

I can explain that the decimal point separates the whole units from the parts. I can explain that in money the decimal places actually refer to parts of a pound. I can explain that in measure the decimal places refer to parts of a metre, kilogram etc. I can apply my understanding of decimal fractions to work out the value of each part of a metric measure.

I can read and write decimal fractions correctly. I know that the place value system can be extended to the right to show numbers between two whole numbers. I can read and write decimal fractions correctly. I can order decimal fractions. I can count forwards and backwards in tenths/decimal fractions, including up and over whole numbers.

I can read, write and order decimal fractions correctly. I can use my knowledge of place value to explain why a decimal fraction is bigger/smaller. I can read, write and order decimal fractions correctly. I can link fractions and decimal fraction by using tenths e.g. 0.2 = 2/10. I can link fractions and decimal fractions where the equivalences are easily visualised e.g. 0.25 = ¼ .

I can use my understanding of decimal place value to work out the value of the marker on a scale. I can split a decimal fraction into parts to show how many tenths it contains. I can round decimal fractions (one decimal place) to the nearest whole number. I can understand the link between a digit, its value and its place.
