Class Topics: 03.06.13

In Math Six today, students discussed their Unit Seven Pretest results with Mr. Giomini as well as last night's Evening Practice.  Once that was complete, students began Lesson 7.1 - Probabilities When Outcomes are Equally Likely.  The terms theoretical and experimental probability where introduced and modeled through different activities.  Other terms that were introduced and defined in class include: outcomes, equally likely, event, probability, favorable outcomes and possible outcomes.
Today's Learning Goals: The student will be able to...

1. add and subtract fractions with like denominators.
2. identify possible outcomes of an experiment.
3. calculate probabilities when outcomes are equally likely.
4. compare predictions based on theoretical and experimental results.

For Evening Practice, the student is assigned one of the following based on the Lesson Quiz results...

1. LI: Study Link 7.1.
2. LII: 9.1 Practice B.
3. LIII: 9.1 Problem Solving.

In Pre-Algebra today, students discussed last night' Evening Practice with Mr. Giomini.  Once that was complete, Lesson 8.7 - More Applications of Percents.  This lesson focused on the formula for simple interest: Simple Interest = Principal * rate of interest * time.  Some of the problems that we dealt with include:

• To buy a laptop computer, Elaine borrowed $2,000 for 3 years at an annual simple interest rate of 5%. How much interest will she pay if she pays the entire loan off at the end of the third year? What is the total amount that she will repay? 
• John’s parents deposited $1000 into a savings account as a college fund when he was born.  How much will John have in this account after 18 years at a yearly simple interest rate of 3.25%?

Today's Learning Goals: The student will be able to...

1. explain the meaning of each variable in the interest formula.
2. tell what should be used for t when referring to 6 months.
3. compute simple interest.

For Evening Practice, the student is assigned one of the following based on the Lesson Quiz results...

1. LI: 1 - 4 and 7 - 16 on page 430.
2. LII: 5 - 12 and 18 - 20 on pages 430 and 431.
