- At a math center in a class, there is a bag filled with 30 red blocks and 20 blue blocks. Each child in the class of 25 will complete the following activity at the math center: Pick a block out of the bag with- out looking, record the block's color, and put the block back into the bag. Each child will do this 10 times in a row. Then the child will write the number of blue blocks picked on a sticky note. Describe a good way to display the data of the whole class. Show roughly what you expect the display you sug- gest to look like, and say why.
