1. After saving up for while, Melanie saved $12 of her allowance. She decided to spend 1/3 of that money at the book fair. the book she wanted was $5. Did she bring enough money to buy the $5 book. Draw a model to justify your answer.

Answer - 12 x 1/3 = 12/3 =4. So she doesn't have enough. But, how do I show that in a model?

  1. One way to draw this model is to draw a line that is 12 units long. Divide the line into three equal parts. Then mark off 5 units. It's more than one or the equal parts.
