Mondays Do Now On your Do Now sheet

Monday’s – Do Now • On your “Do Now” sheet in your own words tell me what an algorithm is…be ready to discuss.

Algorithm for washing your hair… • Step 1: Wet your hair • Step 2: Open the shampoo bottle • Step 3: Pour shampoo in your hand • Step 4: Apply to hair and lather • Step 5: Rinse hair with water • Step 6: Repeat if needed…

Car Wash Problem • The school is having a car wash. On Saturday, 152 people signed up to have their car washed. If one student can wash 25 cars in a day, how many students will have to work on Saturday to finish the job? • Spend a minute brainstorming about how you might solve this problem.

How can I solve using the standard algorithm? •

How do I show without using “remainder”? •

How do you write a remainder as a fraction? •

How do I turn my quotient with remainder into a mixed number? • Now you try…

Now…solve this problem using the division algorithm and write your quotient as a decimal •

When do I stop? • When you get no remainder • When the decimal terminates. * (ends) • When you find a repeating pattern* • *If the decimal goes on and on, stop after three decimal places. * 3. 456789243 3. 457

Now try this in your foldable 200 ÷ 60

Problem #2 Jane has 90 inches of ribbon. She needs to make 16 bows. How many inches should she make each bow to have none leftover? • Sometimes it makes more sense to show the quotient as a MIXED NUMBER. Simply put the remainder in the numerator and the divisor in the denominator.

Problem #3 Bob has $90 to give away to 8 friends equally. How much money will each person receive? • Sometimes it makes more sense to show the quotient as a DECIMAL. To do so you need to add a decimal point and ANNEX a zero.
