Lesson Objective
Lesson Plan
Standard 

6NSO.C8 – Select and use appropriate operations to solve problems involving addition, subtraction, multiplication, division, and positive integer exponents with whole numbers and with positive fractions, mixed numbers, decimals and percents. 6NSO.C10 – Accurately and efficiently add, subtract, multiply and divide (with multidigit divisors) whole numbers and positive decimals 

Aim/Objective: 
Key Points 
· Divide decimals by whole numbers 
· Place the decimal straight up from the dividend to the quotient · Estimate answer · Divide as normal (divide, multiply, subtract, bring down) 
Assessment: 

Tyler spent $409.56 for four new tires for his car. What was the price per tire?
Paco and three friends equally shared the cost of their dinner. If the bill was $33.40, how much did each person pay?


Lesson 

Opening: · Display picture examples of splitting/dividing decimals by whole numbers o Splitting 25¢ by 5 o Splitting 12 kit kat bars by 4 o Splitting 2.4ML by 4
· Discuss that today we are just thinking about dividing when the amount we are dividing is not a nice neat whole number.
Intro to NM · Introduce steps to dividing decimal numbers by whole numbers · When dividing a decimal by a whole number, place the decimal in the quotient straight above the decimal in the divided. Next, divide. · Model two examples of writing the problem – placing the decimal straight up and dividing · In one example show what happens when you still have a “remainder” and continue to add zeros until the number is complete.
Guided Practice: · Students practice two examples – one with a decimal that terminates and one which zeros need to be added. · Students review writing division in different ways – and translate problems into different formats. · Students practice independently
