Method 1:
It will work because if they made the circle equal two.They would have to lower what the triangle and square would equal.They would have to keep doing the pattern and then they would get the right answer.
Method 2:
Yes,because that was the method we used.Square = 8 and triangle = 6. On both coloums it = the right answer.That gives them a clue for all of the other problems.
Method 3:
When we tried the problem it did not work. It is hard to figure out the answer
since he is adding +2 to the triangle to =what the sqaure equals. He is getting the wrong answer when he does that. It also makes no sense and it is to complicated.
Method 4:
When we tried the problem it did not make any sense to us.It also is the same method the person used on number method 3.In method 3 the person made no sense and made the way he got his answer was to complicated.
