Has anyone got much experience of Numicom with G and T pupils (e.g. level 5/6 in year 6)? I'm developing its use in my school and trying to encourage/train teachers how to use it. I'm unsure whether I should expect the year 6 teacher of the higher group to use/try it (i've used it successfully with a lower group), she's very reluctant to use it! I have bought the investigation book and it seems pretty good... What are people's opinions please??
