5. Tangram Value Puzzles
Use the tangrams pieces to figure the dollar amount
What would be the dollar amount for each piece if the whole set had a value of $8.00
Then assume the value for whole set is $12.00
Now find the value of each piece if the whole set where $1.00
Assume the value of each piece depends on size.
