I've used them for years. My kids especially like the activities where I ask a question, they put a chip on the answer, and it makes a self-checking picture at the end - much more fun than a worksheet.
Several years ago, it dawned on me that the traditional hundred board that starts with the 1 in the upper left-hand corner might seem backward to some children.
Starting with 1 in the upper left corner and moving down to add, or moving up to subtract is contrary to our language and our algorithms. Of course, algorithms are not our primary focus in math. However, we do tend to move down for subtraction and up for addition. Even our language says, “Add up the numbers”, “low numbers”, “one step forward, two steps back” and “count down”! I developed this board to help students connect what they hear with what they see.
This board starts with 1 in the lower left corner. It allows students to move up the board as they count higher or add. They subtract and move down the board, more in line with algorithmic directions.
This “upside down” hundred board is just what students need to develop number sense and see how our number system works with our algorithms!
You can get this Little Different Hundred Board as a freebie right here. Please download, try it out, and let me know what you think. I'd love to hear your feedback!
