Per Cent Basics  Using a Map Scale 11M48

Introduction of Lesson

A proportion is an equation comparing two equal ratios. The numbers in the proportion are called terms. A proportion has four terms. Sometimes one of the terms is not know. If you know three of the four terms, you can solve for the unknown.

Eagle Challenge
(35 minutes)

Each student will make correct change for purchases from one dollar and one hundred dollar bills. (Online cash register game)

Learning Tasks/Activities

Class will discuss and explore the steps and rules solving proportions. Class will solve practice problems on the white board. Student will solve proportions using a map scale.

Closure

Oral questioning about rules and steps for solving proportions.

Tuesday


Focus of Lesson
(StudentFriendly Objective)

Relating Percents, Fractions, and Decimals

Introduction of Lesson

Percent, fractions and decimals are different ways to show parts of a whole. You can write a percent as a decimal or a fraction. Since these numbers represent the same amount, only in different forms, we can say they are equivalent.

Eagle Challenge
(35 minutes)

Each student will make correct change for purchases from one dollar and one hundred dollar bills. (Online cash register game)

Learning Tasks/Activities

Students will independently read pages to familiarize themselves with percents. The class will give oral answers to questions about percents on page 173. Class will change percent to fraction to decimal using individual white boards. (174175). Student will solve percent, decimal, fraction problems on the lesson 12 review. (176177)

Closure

Student will state which formula they prefer to use and why.

Wednesday


Focus of Lesson (StudentFriendly Objective)

The Per Cent Formula  Solving for the Part

Introduction of Lesson

Every Percent problem has three elements: the base, the rate, and the part. The base is the whole amount. The base usually follows the word of. The rate is easy to find because it is always followed by the percent sign (%). The part is part of the whole amount. The part is usually precedes or follows the word is

Eagle Challenge
(35 minutes)

Each student will make correct change for purchases from one dollar and one hundred dollar bills. (Online cash register game)

Learning Tasks/Activities

Students will read aloud from lesson 13 about the per cent formula. The class will discuss two formulas to use to find the part in a per cent problem. One is the ratio formula and the triangle shaped formula. Students will choose a formula to use for solving for the part. The class will find the part solving problems on the white board as guided practice. Then the student will solve finding the part problems on page 181 as independent practice.

Closure

Students will check problems for accuracy and correct any missed problems.

Thursday


Focus of Lesson (StudentFriendly Objective)

Ratio, Proportion and Percent  Simple Interest Formula

Introduction of Lesson

Interest is a charge that someone pays to borrow or to use someone else’s money. The amount of interest is charged is based on the principal of amount of money borrowed. An interest rate is used to figure out how much interest the borrower has to pay. You can use the simple interest formula (similar to the percent formula) to find the amount of simple interest owed. interest = principal x rate x time or
i = p x r x t.

Eagle Challenge
(35 minutes)

Each student will make correct change for purchases from one dollar and one hundred dollar bills. (Online cash register game)

Learning Tasks/Activities

Class will practice using the simple interest formula to find interest paid on money borrowed or on items purchased. The class will solve the simple interest problems on page 182 for practice and then problems 1 8 on page 183 independently.

Closure

Students will demonstrate the simple interest formula by stating the formula and then demonstrating it on the board.

Friday


Focus of Less (StudentFriendly Objective)

Using percents with circle graphs.

Introduction of Lesson

Circle Graphs show a whole amount divided into parts. Circle graphs represent parts of a whole with amounts such as dollars, fractions, or percents. The percents in a circle graph add up to 100%.

Eagle Challenge
(35 minutes)

Each student will make correct change for purchases from one dollar and one hundred dollar bills. (Online cash register game)

Learning Tasks/Activities

The class will explore circle graphs by reading the information on page 184 independently. We will then give oral answers to the questions about a circle graph on page 185. The student will solve problems on lesson 13 review.

Closure

Check answers for accuracy on the lesson review then discuss and correct any missed problems.
