We solved our problem by looking at the half shapes and whole shapes. We thought that the half shapes were half the value of the whole shapes. e.g. the full circle is equal to 16, so that means the semi circle equals eight.
For the rest of the shapes that did not have a half shape to go with it, we corresponded the number of sides to the value of the shape. e.g. the hexagon has six sides, so the number value of the shape would be six.
After we figured out the majority of the shapes values we used the shapes we knew the value of to solve the other number value amounts.
