Word Problems-Detailed Explanations of Reasoning and Solving Strategies: Volume 5 Workbook (Paperback) (ISBN-13: 9781492175186)

This is the workbook of Volume 5 of the entire set of 12 volumes of word problems solving strategies. If you want to set a solid foundation in math, grasping the techniques on solving word problems is the key to it. This set of books teaches you the techniques and strategies you need to solve word problems. Sample question in this volume: An elephant weighs as much as 8 cows; a cow weighs as much as 2 horses. If each horse weighs 500 pounds, how much does an elephant weigh? Reasoning and solution: To find the weight of the elephant, we need to first get the weight of 1 cow; to find the weight of 1 cow, we need to know the weight of 1 horse. One horse weighs 500 pounds. One cow weighs as much as 2 horses so when we find the weight of 2 horses, we will know the weight of one cow. One horse weighs 500 pounds, so 2 of them weigh 2 groups of 500 pounds. We multiply the number of horses, 2, with the weight of 1 horse, to find the weight of 2 horses: 2 x 500=1,000 pounds One cow weighs 1,000 pounds. An elephant weighs as much as 8 cows. One cow weighs 1,000 pounds so 8 of them weigh 8 groups of 1,000 pounds. We multiply the number of cows, 8, with the weight of one cow, 1000 pounds, to find the weight of 8 cows: 8 x 1000=8,000 pounds Since 1 elephant weighs as much as 8 cows, 1 elephant weighs 8,000 pounds. The techniques on using the 3 elements formulas to find the total amount in all the groups, the number of groups, and the amount in each group are reviewed and reinforced in this volume. The volume also reviews and reinforces the techniques on addition and subtraction. There is more in the volume than what is mentioned. Detailed explanations of the reasoning and solving strategies for each and every problem in Volume 5 are given in Volume 5 Answer Key.
