Bell Work Vocabulary List
Vocabulary Denominator- the bottom number of a fraction (the whole) Equivalent- equal or the same Fraction- • a number that represents part of a whole or part of a set the greatest of the common factors of two or more numbers Greatest Common Factor- Improper Fraction- a fraction with a numerator that is greater than or equal to the denominator a number that has a whole number part and a fraction part Mixed Number- Numerator- • the top number of a fraction (the part) Product- • the answer to a multiplication equation Quotient- • the answer to a division equation two numbers with a product of 1 (flipped upside down) Reciprocal – Scaling- to increase or decrease a ratio a fraction in which the GCF of the numerator and denominator is 1 Simplest Form-
I Can…… Use models to explore part of a number.
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?” • Quick Check: Complete problems 2-10 on page 91

Bell Work Kelly 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?
Vocabulary Denominator- the bottom number of a fraction (the whole) Equivalent- equal or the same Fraction- • a number that represents part of a whole or part of a set the greatest of the common factors of two or more numbers Greatest Common Factor- Improper Fraction- a fraction with a numerator that is greater than or equal to the denominator a number that has a whole number part and a fraction part Mixed Number- Numerator- • the top number of a fraction (the part) Product- • the answer to a multiplication equation Quotient- • the answer to a division equation two numbers with a product of 1 (flipped upside down) Reciprocal – Scaling- to increase or decrease a ratio a fraction in which the GCF of the numerator and denominator is 1 Simplest Form-
I Can…. 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. • Quick Check: Complete problems 1-6 on page 231

Vocabulary Denominator- the bottom number of a fraction (the whole) Equivalent- equal or the same Fraction- • a number that represents part of a whole or part of a set the greatest of the common factors of two or more numbers Greatest Common Factor- Improper Fraction- a fraction with a numerator that is greater than or equal to the denominator a number that has a whole number part and a fraction part Mixed Number- Numerator- • the top number of a fraction (the part) Product- • the answer to a multiplication equation Quotient- • the answer to a division equation two numbers with a product of 1 (flipped upside down) Reciprocal – Scaling- to increase or decrease a ratio a fraction in which the GCF of the numerator and denominator is 1 Simplest Form-
I Can…. Order fractions on a number line.
Ordering Fractions Essential 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. • Quick Check: Complete problems 7-9 on page 231

I Can…. 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 bothfractions upor 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. • Quick Check: Complete problems 1-16 even on page 15
