One of the hardest things that children have to learn is to be able to carry out a written subtraction in the standard form. One of the main problems for children is the adjustment from tens to units, or hundreds to tens and when to do it. Our great subtraction activities help with this by showing clearly the step by step approach needed on screen. The first looks at subtracting two 2-digit numbers, where an adjustment will always need to be made, because the units on the second line are larger than the units on the top line. The second looks at subtracting two 3-digit numbers where an adjustment will always be made from the hundreds to the tens. The third looks at subtraction of money with an adjustment from the tenths to the hundredths. By pressing return after inputting each number you are automatically taken to the next box to complete. There is a Help link which further explains this step by step approach. All three of these activities need adjustment to take place, but 'in real life' this is not always the case so it would be a good idea to also practice on paper, using some of our subtraction worksheets.
