Class Topics: 12.18.14

In Common Core Math Six today, students developed an understanding of how to estimate with percents.  This topic helps develop a better sense of percent of a number.

Carissa's Corner is offering 20% off a hair dryer that costs $19.99.

If the same hair dryer costs $14.99 at Lester's Discount Haven, 

which store offers the better deal?

Mr. Giomini's personal hair dryer.

Mr. Giomini presented the problem listed below to students as a challenge for today's lesson.  The hope is that this better prepares students for the application of this skill rather than just knowing the algorithm.

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

• apply and extend previous understandings of numbers to the system of rational numbers.
• use your number sense to estimate percent of a number.
• use your understanding of percents to determine 1% and 10% of a number.

For Evening Practice, the student is expected to...

• enjoy the night off.
