If children are finding it difficult to retain times tables facts, make sure that you have resources at hand to support them so that this does not detract from their ability to make good progress in maths generally. Too often, children judge their ability as mathematicians by their ability to recall number facts whereas this is a separate skill. If this is your child, make sure that you have a multiplication square available whenever they are doing maths so that they are not hindered by a lack of knowledge.
This link takes you to a British company which makes flexible multiplication grids which I have used for years in my teaching.
Calculators can also be used to give the answer but seeing the numbers on the grid in relation to other numbers in the same time-stable is more beneficial in aiding memory retention of tables facts.
Don’t be pressurised by the expected standards. It is more important that a child gains success and can see themselves making progress at whatever age and stage of education. Start by learning the 10’s because it is a very clear pattern. Then the 5’s and then the 2’s. The five times table is useful when learning to tell the time because the minute hand moves five minutes between each number on the analogue clock face and the 2 x table links well with work on odd and even numbers. When children have mastered the 2 x table, they can double each answer to learn the 4 x table and then double these answers to learn the 8 x table. There is a similar pattern with the 3 x table and the 6 x table; by doubling the answers to the 3 x tables, you can find the answers to the 6 x table and then onto the 12 x table.
This link will show you how to use your fingers to calculate the 9 x table.
