I LOVE graphing with my 4's!! And they sure do love sharing things they love. I created a reusable graph on a plain white poster board and with a permanent marker drew out the basis for a bar graph. Then the poster was laminated for durability. I cut out squares to create responses, for this particular graph we did a "blind" taste test for different types of foods and we graphed if we liked the food or not. Red square construction paper was taped into the appropriate place. At the end we talked about what foods we liked the most which one we liked the least. This graph as worked out very well!!
