DO YOU WANT YOUR CHILDREN TO SUCCEED? I have three children who are still in school, and like you, I also want my children to succeed in life. Our children's success is what inspired me to write this book. Research shows that the more vocabulary words an elementary school student knows, the more likely he or she is to do well in middle and high school. Research also shows that there is a direct link between a student's vocabulary and their reading comprehension skills. Consequently, the more words elementary school students learn, the better readers they will be, and the more likely they will be good students in high school and successful as adults. I became concerned when my daughter began to show difficulty with reading comprehension. Her biggest problem appeared to be not knowing the meaning of many important words in her reading material. In speaking with my daughter's teacher I was shocked and disturbed to learn that with the new Common Core requirements, teachers don't have the time to teach the definitions of words like they used to. Instead, they are forced to concentrate on spelling and teaching a limited number of definitions. So I began to look for a way that parents can help their children learn the definitions of words so that reading is fun . 4th Grade Vocabulary Building Crossword Puzzles is the result.

Straights is a logic puzzle.The solver is given a 9x9 grid, partially divided by black cells into compartments. Each compartment, vertically or horizontally, must contain a straight - a set of consecutive numbers, but in any order. For example: 7, 6, 4, 5 is valid, but 1, 3, 8, 7 is not. Like sudoku, the solver must fill the remaining white cells with numbers 1 to 9 (or 1 to n in puzzles with N cells per side) such that each row and column contains unique digits. Whereas Sudoku has the additional constraint of 3x3 boxes, in Straights rows and columns are divided by blacks cells. Additional clues are set in some of the black cells - these numbers remove that digit as an option in the row and column. Such digits do not form part of any straight.
