Row 1

Lesson 1

LI: Derive facts to 100.

If we know our number facts to 10 then we know our number facts to 100.

7 + 2 = 9                                  5 – 3 = 2

So                                            so

70 + 20 = 90                           50 – 30 = 20

29 + 30 = 59      20 + 30 = 50 + 9 = 59

Lesson 5

LI To understand how addition and subtraction is linked

9 + 3 = 13  If we put this into a number triangle

9                    3                  3+ 9 = 12

                                          12 – 9 = 3

                                          12 – 3 = 9
