Let the instructer ask the pupil the divisions of aunit in this manner as far as the division into 10 parts. It would be well to ask them further. Then let him begin again, and suppose an orange instead of an apple. After applying the division to several different things, Plate II. may be explained and used. It will often be found useful to refer the pupil to the divisions of some sensible object. For the explanation of Plate II. see the Key. 12. A man had a bushel of corn and wished to give 1 half of a bushel apiece to some labourers ; how many could he give it to ? 13. How many halves are there in 1 ? 14. A man divided 2 barrels of flour among his labourers giving them 1 half of a barrel apiece, how many men did he give it to? 15 How many halves are there in 2 ?* 16.

A boy divided 4 oranges among his companions, giving them 1 half of an orange apiece; how many boys did he give them to ? 19. How many halves are there in 4 ? * Be careful to make the pupil use the plate. He might answer the questions without, but he will not understand their meaning so well. 17. 20. A man having some labourers gave them 1 half a dollar apiece ; it took 3 dollars and 1 half a dollar to pay them; how many labourers were there? 21. How many halves are there in 3 and 1 half? 24. How can you tell how many halves there are in any number? Answer. Since there are 2 halves in one, there will be twice as many halves as there are whole ones. 25.

Answer. Since there are 3 thirds in one, there will be 3 times as many thirds as there are whole ones. 32. If you had 2 bushels and I third of a bushel of corn to give to some poor persons, how many could you give it to if you should give them 1 third of a bushel apiece ? 33. How many thirds are there in 2 and 1 third ? 34. If a horse can eat I third of a bushel of oats in 1 day, hov many days would it take him to eat 3 bushels and 2 thirds of a bushel ? 35.
