Part and Whole

• Essential Understanding: • To determine a part of a number or whole, determine how

many groups or parts the whole is being divided into. Then divide the whole by the number of groups/parts determined.

• Think: “ How many groups or parts are needed? and How many or how much can go into each group equally?”

Day 2

Bell WorkKelly makes $80 a week babysitting. Each week she

deposits of her earnings into a savings account. How

much money does she put into the account each week?

Justify your answer.Kelly is saving her money to buy a prom dress. The dress she has picked out will cost her $400. She estimates she will have enough money, after 6 weeks of saving. Is she correct? Why or Why not?

How many weeks will she need to save, before she can purchase the dress?

Compare fractions.

Comparing Fractions

Essential Understanding: There are several strategies we can use to compare fractions. In this lesson, you will use your knowledge of LCMs to generate equivalent fractions with common denominators before comparing.

This can be accomplished easily by using the least common multiple to generate equivalent fractions. Remember to multiply both the numerator (top) and the denominator (bottom) by the same number (this process is called scaling). Once all fractions have a common denominator, you can simply compare the numerators.

Order fractions on a number line.

Ordering FractionsEssential Understanding: Like comparing fractions, there are many strategies we could use to put a set of fractions in order. In this lesson, we will continue to use common denominators to compare, then order the given fractions

Reminder: This can be accomplished by using the least common multiple to generate equivalent fractions.

First multiply both the numerator (top) and the denominator (bottom) by the same number (this process is called scaling).

Next, compare and order the fractions by their numerators.

Finally, simplify each fraction and plot on number line.

Add and Subtract fractions.

Adding and Subtracting Fractions

Essential Understanding: To find the sum or difference of fractions, you must first identify a common denominator. Remember to scale both fractions up or down until you reach the LCM. Once all fractions have a common denominator, you can simply add or subtract the numerators (the denominator will stay the same). Simplify when possible.
