This week you will need to make sure your feedback comment from your parent(s) is entered in your e-portfolio. If you need help with this, please see me or come the eportfolio group session on Wed Period 5, M1. You will need to be thinking about a new goal for mathex for this half of the year. We will put these into our eportfolios in class, but you could be prepared by thinking about and writing up your goal now.
 * E-portfolios:**

1. Ranui bought birthday presents that were going to cost him $75, but was given a 15% discount for cash. What did he pay for presents? 2. A house in the street sold for $205,000.
