Has anyone got an inspiring 
:o idea / resource for securing / improving / reinforcing times tables knowledge in a very unmotivated and resistant child who has so far managed to avoid learning them properly, and will be going into Year 4 in September? She knows the easy ones and the "trophy" ones (she can tell you 7x7=49, but not what 4x7 is, without sitting for ages and doing 4+4+4+4).
She can bluff her way through, but her lack of tables knowledge means her homework (which assumes secure knowledge of all the tables as a prerequisite now) is taking ages and making her frustrated and grumpy, and they do a lot of tests at school, which she often gets a lower grade in despite getting most questions correct, because she doesn't finish because not having automatic recall of her tables means she takes three times as long on some questions).
She is very stroppy and resistant to old fashioned drilling or testing on her tables for more than about 30 seconds, so wondering if there is a more interesting resource she might use over the summer to drum them in before she starts year 4...
