1 | Pupils explain that 100 is composed of ten tens and one hundred ones |

2 | Pupils explain that 100 is composed of 50s 25s and 20s |

3 | Pupils use known facts to find multiples of ten that compose 100 |

4 | Pupils will use known facts to find a two-digit number and a one- or two-digit number that compose 100 |

5 | Pupils use known facts to find correct complements to 100 |

6 | Pupils use known facts to find complements to 100 accurately and efficiently |

7 | Pupils represent a three-digit number which is a multiple of ten using their numerals and names |

8 | Pupils use place value knowledge to write addition and subtraction equations |

9 | Pupils bridge 100 by adding or subtracting in multiples of ten |

10 | Pupils use knowledge of addition and subtraction of multiples of ten bridging the hundreds boundary to solve problems |

11 | Pupils count across and on from 100 |
