there were 116 cases of Covid 19 in Auckland, 58 cases in Counties
Manukau, 117 in Waikato, 118 in the southern and 108 in Waitemata.
QA How many cases are there altogether in the five areas?
116 + 58 + 117 + 118 + 108 = 517
100 + 100 + 100 + 100 = 400
10 + 50 + 10 + 10 = 80
6 + 8 + 7 + 8 + 8 = 37
400 + 80 + 37 = 517
6 + 8 + 7 + 8 + 8 = 37
400 + 80 + 37 = 517
QB How many cases are there in Auckland and Counties Manukau altogether?
116 + 58 =
100 + 0 = 100
10 + 50 = 60
8 + 6 = 14
100 + 50 + 14 = 164
QC How many cases are there in Waitemata and Southern altogether?
118 + 108 =
100 + 100 = 200
10 + 0 = 10
8 + 8 = 16
200 + 10 + 16 = 226
Well done Genevieve. It is good to see you using place value partitioning to solve addition problems. Keep up with your good work.
