Without counting, determine the number of dots and explain how you got your answer.
Here is an applet to use if you choose to.
The toolbar includes buttons that represent 1 whole and fractional parts, as shown here. Click a button to choose a quantity, and then click in the work space of the applet window to drop it. When you're done choosing pieces, use the Move tool (the arrow) to drag them into the jars. You can always go back and get more pieces, or delete them with the Trash Can tool.
Draw a diagram and write a multiplication equation to represent the situation. Then answer the question. Mai had 4 jars. In each jar, she put 2 ¼ cups of homemade blueberry jam. Altogether, how many cups of jam are in the jars?
