To continue develop my understanding of the strategies in the mathematician toolbox.

Today’s problem was to find out how many tiles there were all together in the dominoes. Link to the site: http://www.problempictures.co.uk/examples/op09.htm. *During the process, *It wasn’t difficult, but at the beginning it was quite confusing, after a while I thought a strategy that would help would be to draw a diagram which had helped a lot through the progress of finding the answer. What worked for me was to drawing the diagram since I did not get lost in any part of the problem because I had my working out on pieces of paper. **Something that did not work was** not having the a diagram because the first time I tried it I had gotten stuck and did not now what to do. My estimate and answer at the end was 55 tiles inside the domino which ended up being the correct answer.

**New goals I want to achieve**

Is to know all of the mathematician strategies off the top of my head and to ask more questions that leads to clarifying the things I don’t now.

Below are the steps I used

predict:

I predict that this text is going to be how many dominoes and adding then and subtracting.

*Read*

A normal set of dominoes has 28 tiles and the largest is “double six.” This special domino set has more tiles and the largest is “double nine.” How many tiles does it have?

You can buy domino sets going up to “double twelve.” How many tiles would these sets have?

A normal set of dominoes can be matched up to make a continuous chain that uses all the tiles. Why is this impossible with the set in the photograph?

**CLARIFY:**

I have nothing to clarify in this text today.

*Whats the big question?*

The big question is how many tiles does it have.

*WHAT IS THE ANSWER *

55

How I worked it out:

I was connecting and doing a pattern to 9 I stared from 0 and went 0/0 and so on.

*Summary:*

I think I worked very good and I don’t think I need any help
