Display 2 + 1/2. Draw a strip diagram to show 2 ones. To know how large to draw 1/2, let's partition each whole number into 2 halves. (Demonstrate partitioning the 2 ones with dotted lines.) Partition the ones, and extend your model to add 1/2. Say a number sentence that adds the whole number to the fraction.
