Solve for each shape value. This puzzle is appropriate for grade 3 and up.
Notes on the problem:
This puzzle reflects the algebraic thinking supported and encouraged throughout the Singapore Math curriculum. By recognizing that three of the same shape require a total quantity to be distributed equally between them, students make a connection to the concept of partitive division. They then transfer the value of one unit to find the value of the others. This allows the development of flexible problem solving in multi-step problems. It is related to the thinking used in bar model strategies for word problems.
