This is one of the math stations I start at the beginning of the year and use all year long. I order the plastic bean counters on Amazon that are red and white so you can bleach them when one accidentally ends up in someones mouth. . .but you could easily just spray paint beans red on one side. My kinders do the sheet that matches their "Target Number" by shaking a container of their beans and dumping them out, coloring a picture of their beans, and writing an equation for each picture (red+white=total).
