This is the answer key of Volume 3 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: A parking lot has 8 trucks and 6 times as many cars. How many cars are parking in the parking lot? Reasoning and solution: 6 times means 6 groups so we can use the 3 elements formulas to solve the problem. Let's first find the amount in 1 group. Look for the noun or noun phrase after the second "as" in "as...as...": (as the number of trucks) so the number of trucks in the parking lot is the amount in 1 group. We are comparing the number of trucks with the number of cars so the number of cars is the amount in all the groups. The number of cars= the number of trucks (the amount in 1 group) x the number of groups = 8x6=48 cars 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 taught in this volume. The volume also teaches using the terms "times" and "as......as......" to solve for one of the 3 elements. The techniques on addition and subtraction (for numbers 0 to 100) are reinforced in this volume. 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 3 are given in this book.
