This week we have been adding and subtracting two-digit numbers. The children have been flexibly using different methods to solve problems involving addition and subtraction and also choosing which method is most efficient. At home you can practice subtracting two-digit numbers. Using a blank number line to jump back in 10s and 1s; the vertical method where you put one number underneath the other to subtract; working mentally to subtract the 10s and then the 1's.
