This textbook includes the following contents: Addition and subtraction within 100 (b), centimeters and meters of knowledge, the table multiplication (a), table division (a), angle and right angle, table multiplication and table division two). The focus of this book is on-the-table multiplication and division. First, to improve less than one hundred percent of the addition and subtraction of partial row The teaching of addition and subtraction of the main contents are: even add, even minus, add and subtract mixed calculation and two consecutive questions. Students have learned in front of the mouth count plus, minus and mixed addition and subtraction calculations. This book teaching pen calculations. Teaching, the temporary does not appear to increase the number of vertical written three, first stressed that written in two vertical, step-by-step calculation. On this basis, re-teaching earthen writing, that is, two vertical connection
