Henry's Matariki Poster

These are some facts Henry found out about Matariki after reading the article 'Matariki Returns' with my reading group. One thing he didn't know was that Matariki is a sign to Maori that the hunting season is over.

Henry's Maths

DON'T SUBTRACT, ADD

1. Moana has $81 and she gives her friend $18. How much money does Moana have left?

18 + 2 = 20

20 + 60 = 80

80 + 1 = 81

       18 + 63 = 81 so 81 - 18 = 63

2. Jake collected $75 from his pocket money to buy a present for his mum. The present only costs $39 so how much change does he have? 
   39 +1=40 
   40+30=70

      70+5=75       

      39 + 36 =75 so 75 - 36=63 ✔

3. Dad takes $93 with him to the fair. He comes back with $57. How much did he spend?

57 +3=60

60 +30=90

90+3=93

so 57+36=93 so 93-57=36✔

At the park the lolly seller has collected in $103.

She has to pay $88 out for buying lollies for the next day. How much money does she have left?

88+2=90

90+10=100

100+3=103

so 103 -88=15✔

4. Sam has $110 and spends $89 on some playstation games he wanted. How much money does he have left?

89+1=90

90=20=110

                                so 110-89=21 ✔

5. I start shopping with $64 and come home with $38. How much did I spend when I was out shopping? 
   38+2=40

     40 +20=60

     60+4=64

     so 64 -38 =26✔

The hard thing was counting in my head.

6. I wanted to collect $100 for charity, but only managed to get $82. How much less than $100 is that? 
   82+8=90

              90+10=100

               so 100-82=18 ✔

We were learning that sometimes we can use our adding strategies to help us solve subtraction questions. I found counting in my head difficult.

Teagan, Kyra, Deannika, Kataraena, Puke, Pah Nwee and Henry worked collaboratively on this research task. Their challenge was to find three facts about each event, summarise their information and record their findings in their own words. Each slide acknowledges the websites where they found their information if you would like to read about these events in more detail.
