 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   Complete the worksheet in your pack
 Lesson 2 LI: Add 2digit numbers and tens When we add tens we know that our ones column doesn’t change.   30+ 10 = 40      We can add the tens together then add the ones   35 + 10 = 45    30 + 10 = 40 + 5 = 45   29 + 30 = 59      20 + 30 = 50 + 9 = 59   Complete the worksheet in your pack
