The act of splitting an object or value down into smaller parts

Use place value and number facts to decompose 4-digit numbers in different ways

Maths

In this unit pupils will compare and order 4-digit numbers. They will learn what rounding is and will round 4-digit numbers to the nearest 1000, 100 and 10. They will count backwards through 0. In the future unit pupils will consolidate column addition with regrouping and column subtraction with exchanging. They will use known facts and strategies to accurately and efficiently calculate and check 

In the prior unit pupils used knowledge of place value to represent a 3-digit number in different ways. They compared and ordered 3-digit numbers and positioned on number lines and unmarked number lines. In this unit pupils will compare and order 4-digit numbers. They will learn what rounding is and will round 4-digit numbers to the nearest thousand, hundred and ten and count backwards through 0.
