Review and use knowledge of place value to correctly lay out column addition

Maths

In this unit pupils will revisit column addition with regrouping and column subtraction with exchanging to solve problems. They will read Roman numerals to 100. In the future unit pupils will consolidate column addition with regrouping and column subtraction with exchanging to solve problems. They will use known facts and strategies to accurately and efficiently calculate and check.

In the prior unit pupils identified the minuend and the subtrahend in column subtraction and explained the column subtraction algorithm. They subtracted from a 2-digit number using column subtraction with exchanging. In this unit pupils will revisit column addition with regrouping and column subtraction with exchanging to solve problems. They will read Roman numerals to 100.
