Practise your times tables. Focus on the times tables you know you are weak on.
Do not just write them out and finish.
Write them out once i.e 7 times table. 0,7,14,21...84
Tear some paper up into rough squares and write the number of times, i.e. 8 x and on the back write the answer i.e 56.
Use these to test yourself.
Practise, practise, practise.
It will make a huge difference in your maths progress if you can improve your times tables knowledge.
