4 to 12 Maths
My 3 kids were fighting to get on the computer last night to do Maths. I think its brilliant - they even missed X-factor to do Maths!

    • Show the numeral
    • Count down to zero
    • Counting back number rhymes
  • Subitise (tell at a glance) the number of objects in a set, 1-5
    • Tell at a glance how many objects are in a set
    • Estimate using a known set
    • Without counting, classify the other sets as less than/about the same as/more than the given set
  • Solve simple oral problems, 0-5
    • You have 3 sandwiches for lunch, you eat 2, how many are left? Zero can be used when there are none left.
