Marino’s Maths learning Story
The Problem:
Unveiling
Marino and Julie are in Rarotonga celebrating Poppa Joe’s
unveiling. 235 people were invited to the celebration but then 68 people didn’t show up. How many people came to the unveiling?
What different ways can you solve this problem?

How we solved the problem:
First I drew an equation which was 235 -68=
Then I split the 68 into 34 and 34. Then I did 235- 34=201. Then 201-34=167
Finally I found out that there was only 167 people at the unveiling.
Another way to solve the problem
First I wrote 235- 68=.Then I wrote ,68+2 =70. Then 235- 70 =165.Then 165+2 =167. Then 235
-68=167
I added 2 because 70 is easier to subtract. Then I had to make up for it later by adding back
on the extra 2 I took away.
Finally I proved that there was only 167 people at the unveiling.

Working as a group is important: Choose 2 to write about
I am good at…. because….
I am getting better at ….. because …..
It’s hard for me …… because …...
I need to work on because….

It’s hard for me to share my ideas because I disagree by friendly arguing with people.
It’s hard for me to work in my maths group because I like to hold the pen a lot but I need to
get better at sharing the pen.
get better at sharing the pen.
