Day 93: Estimate to Find Percent / Simple Interest

Students in Math 6 received their Topic Six Midpoint Quiz back from Mr. Giomini. Time was spent on looking over the back part of the assessment which is where students struggled. Mr. Giomini then introduced Lesson 6.4: Estimate to Find Percent. This lesson focused on using compatible numbers to help students generate possible "ballpark" answers to percent problems.

 

During Math 6+, students received their Topic Six Midpoint Quiz. A brief discussion was had over a question dealing with percent change. Mr. Giomini then introduced the concept of simple interest to the students. Examples of how simple interest is used was shared: CD deposits, car loans, consumer loans (Best Buy and Home Depot), and discounts on early payments.

Today's Lesson Objective(s):

• Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. (6th Grade)
• Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. (7th Grade)
