Why is it important use and interpret formulas? We use formulas in everyday life such as carpentry, medicine and especially shopping Read the importance and have students share other reasons why it is important to understand hyperbole Ask for other suggestions regarding importance.

Example: the formula for finding the area of a rectangle is A = ℓ x ω formula- a set of symbols and variable in mathematics that expresses a rule. Example: the formula for finding the area of a rectangle is A = ℓ x ω A ω= 2 Concept development Introduce meaning of hyperbole, have students pronounce exaggeration Give an example Have students pair share the meaning of hyperbole and tell why the example is an hyperbole Use TAPPLE ℓ= 4

Steps to using formulas Step 1 : Read the formula Step 2: Identify the operation Step 3: Plug in the values Step 4: Solve problem using formula Yonathan bought candy and gave an equal amount to his 8 cousins. He figured out how many pieces of candy each cousin would receive by using this formula Number of pieces per cousin (X) = Total number of pieces (Y) ÷ 8 How many pieces of candy did each cousin get if Yonathan bought 48? What if he bought 24 pieces? If each cousin got 2 pieces of candy how many total pieces did Yonathan buy? X = Y ÷8 X = 48 ÷ 8 X= 6 Guided Practice Remember to slowly release students have X = Y ÷ 8 X= 24 ÷ 8 X = 3 X = Y ÷ 8 2 = Y ÷ 8 2 x 8 = 16 Y = 16

Steps to using formulas Step 1 : Read the formula Step 2: Identify the operation Step 3: Plug in the values Step 4: Solve problem using formula There are 28 students in Ms. Troy’s class. The number of boys in her class can be found using this formula Number of boys (B) = 28 – the number of girls (G) If there are 20 girls, how many boys are in her class? If there are 12 boys, how many girls are in her class? B = 28 - G B= 28 – 20 B = 8 Guided Practice Remember to slowly release students have B = 28- G 12= 28- G G = 28 – 12 = 16

Steps to using formulas Step 1 : Read the formula Step 2: Identify the operation Step 3: Plug in the values Step 4: Solve problem using formula Janet sold water to raise money for a trip. This is the formula she used to figure out how much money she made $3 x the number of bottles of water (W) = total money she made ($) How much money did he make if he sold 5 bottles of water? If Janet made $ 30.00 how many bottles of water did she sale? 3 x W = $ 3 x 5 = $ $ = 15 Guided Practice Remember to slowly release students have 3 x W = $ 3 x W = 30 W = 30 ÷ 3 = 10

What did we learn about today? Why is it important? Step 1 : Read the formula Step 2: Identify the operation Step 3: Plug in the values Step 4: Solve problem using formula The area of a rectangle can be found using this formula Area = Length (ℓ ) x width (ω) What is the area of a rectangle that has the a length of 5cm and a width of 3cm? If the Area is 21in² and the length is 3in what is the width? A = l x w A = 5cm x 3cm A = 15cm² A = l x W 21 in² = 3in x W = 21 ÷ 3= 7 in

Number of boys (B) = 28 – the number of girls (G) There are 27 students in Mrs. Delpit’s class. The number of boys in her class can be found using this formula Number of boys (B) = 28 – the number of girls (G) If there are 20 girls, how many boys are in her class? If there are 12 boys, how many girls are in her class?

$6 x the number cakes (C) = total money she made ($) Janet sold cake to raise money for a trip. This is the formula she used to figure out how much money she made $6 x the number cakes (C) = total money she made ($) How much money did he make if he sold 8 cakes? If Janet made $ 36.00 how many cakes did she sale? Guided Practice Remember to slowly release students have

Area = Length (ℓ ) x width (ω) The area of a rectangle can be found using this formula Area = Length (ℓ ) x width (ω) What is the area of a rectangle that has the a length of 7cm and a width of 3cm? If the Area is 21in² and the length is 7in what is the width?

Number of pieces per cousin (X) = Total number of pieces (Y) ÷ 3 Stacey bought candy and gave an equal amount to her 3 cousins. She figured out how many pieces of candy each cousin would receive by using this formula Number of pieces per cousin (X) = Total number of pieces (Y) ÷ 3 How many pieces of candy did each cousin get if Stacey bought 15? What if he bought 24 pieces? If each cousin got 2 pieces of candy how many total pieces did Stacey buy? Guided Practice Remember to slowly release students have
