ARITH. FIFTH YEAR-SECOND HALF. 629249 C PREFACE THIS book has been prepared for the purpose of simplifying the study of arithmetic and of fixing its facts in the memory. It includes work for the second half of the fifth year, divided into five main parts, corresponding to the months of the usual school term. Each of these parts is again divided into twenty groups of problems, corresponding to the usual number of school days in a month. One half of the oral and the written work in each group of problems will require for completion the attention of an average class for about thirty-five or forty minutes. Each month's work is preceded by an outline of the topics to be studied, in which the new work is distinguished from the rest by being printed in full-faced type. Provision is made for frequent reviews, including rapid calculations in the fundamental processes and examples in the most important parts of the arithmetic previously studied. By this means a proper perspective of the subject is maintained. While most of the material has been selected for pupils of average ability, additional problems are given for pupils of advanced standing. These problems can be used also for variety, when pupils are required to go over the grade work a second time. |
