U = understand or underline important parts of question. Part of understanding I guess. C = Choose calculation - What operation and the 'number sentence'. Also need to decide on the units the answer will be in. S = Solve. Carry out the chosen calculation. A = Answer. Write out the full answer including units. C = Check. Check to see if it really makes sense. Carry out any inverse operation calculations etc. Even share with a friend.
