Students play with the idea of decomposing rectangles by trying to “cover the field” – a larger rectangle – with smaller rectangles they create with numbers generated by rolling dice. Students must think flexibly about what rectangles they make and how they fit them into their field.

These materials were developed by Dr. Jo Boaler and include:

• The game board and a recording sheet
• Game directions
• Discussion questions to use with students
• Some “Look-Fors” to help teachers monitor student engagement and understanding.
