Pencil puzzles with numbers can be fun as well as challenging. Using the style of a crossword puzzle, you need to decide where to place the selected numbers, so that all are used and all “fit” in the diagram. Numbers can go left to right or top to bottom.
In this classroom puzzle book, Rich Rollo has created a series of challenges in varying levels of difficulty. A teacher’s edition is also available, with answers to the puzzles.
I have to qualify my comments about this book by first stating that I am a math nerd. I enjoyed number puzzles of great difficulty when I was in high school, and would eagerly spend hours or even days working on the same puzzle. Number puzzles can be incredibly fun. However, this book provides a very simple version of these puzzles, geared toward younger children. Adults or older students will not find much challenge in these puzzles that may only take five minutes to solve.
