Lesson 5.2.1 – Teacher Notes Standard: 6.RP.A.3c Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. 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. 6.NS.B.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. equivalent expressions. Chapter 7 – Connects fraction division to decimal division Chapter 9 – Focus on percentages Lesson Focus: Focus of the lesson is to relate multiplication of decimals to real-world situations. Teachers may choose to refresh students understanding of the percent ruler with the below focus problems. Teacher may choose to teach only 5-39 and 5-40 then supplement the remainder of the lesson with a worksheet covering decimal operations. (5-39 and 5-40) I can perform operations with decimals. Calculator: No Literacy/Teaching Strategy: Teammates Consult (5-39); Hot Potato (5-44)

BELLWORK

PRACTICE REVIEW Multiply normally, ignoring the decimal points. Then put the decimal point in the answer-it will have as many decimal places as the two original number combined.

PRACTICE Without using a calculator, find each of the following products. 4.15 • 0.923 7.79(8.5) 2.67 × 0.59 0.15• 3.78 0.193(0.48)
