FIG. 85. The pupils will readily rearrange the rods in two groups, moving the orange rods to one side, since they already know how easy it is to add tens together. They then add the units. Since the result of this addition is expressed in the decimal system, that is by using as many orange rods as is possible and supplementing the length with the appropriate rod, they will in this case have formed the length orange plus pink. They can see that by putting the orange rod with the others, the answer immediately becomes apparent: 7 orange rods + 1 pink rod
