Tekau Ma iwa- student Voice:

Writing our own problems and then answering other problems, really made us become problem finders!!

We had lots of discussion about the best way we can explain our thinking and how we could come up with an efficient strategy that makes sense to us. 

These problems are challenging.  Congratulations for not giving up. Your perseverance skills are to be commended! 





Grace:
" I learnt 14 + 14+ 14 + 14 + 14 + 14+ 14 = is the same as 7 groups of 14 and it makes 98.
I know 7 X 10 = 70
I know 7 X 4 = 28

I know 78 + 28 = 98

I can show this on an array too"



Vera:
I learnt how to use the place value blocks. 
I used 1  X 100 block and three ten blocks. This makes 130.

I figured out how many 5's go into 100 which is 20. Then I did the same with the 30, I know 3 tens are in thirty and there is six 5's in 30.  

20 + 6 = 26
I know there are 26 5's in 130. 
So 26 X 5 = 130 or 130 divided by 5 is 26.




Tanya:
I learnt that if you halve 10 it would be two sides of 5. 
So if you had 90 balloons and needed to give each of the five children the same amount then you... Wait..., There are 9 tens in 90, so you double 9 to make 18. 

And that is the same as doubling 5 to make 10. So there are 18 5's in the number 90. 


Isabelle:
I learnt that 56 divided by 8 is 7

Because I used the 56 place value blocks to make equal groups. I used four tens and split them equally. So I had 8 groups of 5 = 8x 5 = 40 . 
Then I added the ones, that meant there were 7 in each group."
