WELCOME TO THE EGG-STRAVAGANZA DINER Slide 2 GREEN EGGS & HAM DR. SUESS video skit of Green Eggs & Ham video skit of Green Eggs & Ham Slide 3 Today we will be ordering, eating, and working at one of Dr. Suess favorite restaurants, the Egg-stravaganza Diner. Inside your crates, you will find a set of menus. With your partner, read over the menu items, the special of the day, and the prices listed. Slide 4 Egg-stravaganza Diner Menu Green Eggs$2.25 Regular Eggs$2.00 Ham$1.50 Bacon$1.25 Small Drink$0.75 Large Drink$1.00 Todays Special$4.25 Slide 5 In a diner, time and efficiency are of utmost importance, so there is a shorter way we will write down a customers order. It takes too long to spell out each menu item so each item will be abbreviated using only the first letter. For example, if a customer ordered green eggs, the waiter would write G. Todays special, which is green eggs, ham, and a large drink, is abbreviated as X. Slide 6 For now, you will be assisting the cook (Ms. Owens) and telling her what has been ordered. Lets look at some tickets! Slide 7 Sample order G + H + S What did the customer order? Green eggs, ham, and a small drink How much is this order ? $4.50 Lets share how we calculated this cost mentally ! Slide 8 With your partner, I would like you to look at three more orders that have been sent to the kitchen. Together, determine what was ordered and then mentally calculate the cost of each. Be ready to share your strategies. #1 #2 #3 X + G + S = ? 2G + B = ? E + 3H + 2L = ? Slide 9 Order #1 X + G + S = ? What did the customer order? Do you think this was just one person? A special, Green eggs, and a small drink How much is this order ? $7.25 Lets share how we calculated this cost mentally ! Slide 10 Order #2 2G + B = ? What did the customer order? What does the 2 in front of the G mean? 2 orders of green eggs and one order of bacon How much is this order ? $5.75 Lets share how we calculated this cost mentally ! Slide 11 Order #3 E + 3H + 2L = ? What did the customer order? What does the 3 in front of the H and the 2 infront of the L mean? Eggs, 3 orders of ham and 2 large drinks How much is this order ? $8.50 Lets share how we calculated this cost mentally ! Slide 12 The cook has a few more large orders that have been sent to the kitchen. With your partner, discuss what was ordered and then calculate the cost of the bill. Make sure that BOTH partners are prepared to share their strategies. Slide 13 Orders (partner work) #4 #5 2(G + H) = ? (G + S) + 2H = ? #6 #7 X + 3(E + L) = ? 3(E + B + L) + 2X = ? Slide 14 Exit ticket: You have $10 to spend at the Diner. Create an order ticket using our abbreviations, then calculate the cost of your order. (Try to spend as much of the $10 as possible.) Explain how you determined the total cost. Slide 15 Yesterday, we shared how we could write our orders in more than one way. Lets look at an example. 4(B + E) Is this the same as 4B + 4E? Prove it!! Day 2 Slide 16 Guided Practice Rewrite each order in a different way without changing what has been ordered! Slide 17 3E + 3B + 3L 3(E + B + L) (G + H + S)2 2G + 2H + 2S Slide 18 2x + 3L + 3B + 3E 2X + 3(L + B + E) 2(L + E) + 3(G + S) 2L + 2E + 3G + 3S Slide 19 3(H + E + S) 3H + 3E + 3S 2S + 2E + 4G + 4L 2(S + E) + 4(G + L) Slide 20 Does anyone know what this process is called mathematically? Hint: We are distributing the outside number to everything in the parentheses. Slide 21 Notes The Distributive Property **The word distribute is often used in the English language. It is defined as: to give out or deliver especially to members of a group. It can help you remember that in Mathematics, the Distributive Property tells you to distribute the factor on the outside of the parenthesis to the terms on the inside. Slide 22 Words to multiply a number by a sum, multiply each number inside the parentheses by the number outside the parentheses. It combines addition and multiplication. Symbols: a(b + c) = ab + ac (b + c)a = ba + ca Examples: 3(4 + 2) = 3(4) + 3(2) (5 + 3)2 = 5(2) + 3(2) Slide 23 On your board, find the product of 23 X 12. Analyze your work and discuss with your partner a way to PROVE that you used the Distributive Property to solve. Can you use the Distributive Property to solve this mentally? Slide 24 Try these on your dry erase board. A) 15 x 13 B) 21 x 27 C) 26 x 14 Slide 25 Time for Sage & Scribe!! Remember the Sage is like the coach while the scribe writes only what the sage says. Switch after each problem. Slide 26 ALEXIS AND CRYSTAL HAVE TO BUY PARTY FAVORS FOR A PARTY. GLOW STICKS COST $2 PER PERSON AND TECH DECKS ARE $5. ALEXIS AND CRYSTAL NEED ENOUGH FAVORS FOR 10 PEOPLE. WRITE AN EXPRESSION TO REPRESENT THIS SITUATION. Lets look at a real-life example!! 10 (5 + 2) OR (10 X 5) + (10 X 2) Evaluate in both ways now. 10 (7) = 70 OR 50 + 20 = 70 Slide 27 Cadets at the Naval Academy have to purchase uniforms. A jacket costs $36 and the pants are $29 a pair. They must purchase 4 uniforms. Write two expressions to represent this situation. Find the total cost by evaluating the expressions. Exit ticket: Slide 28 Yesterday, we practiced writing our diner orders in more than one way WITHOUT changing what was ordered. Lets review! 3(G +H + L) + 2(E + S) 3G + 3H + 3L + 2E + 2S What is this called mathematically? Slide 29 We also tried this with multiplication. Lets review! 22 X 14 Solve using the Distributive Property. (22 X 10) + (22 X 4) 220 + 88 308 Why would using the Distributive Property be a good strategy for this problem? Discuss with your team. Slide 30 Time to match equivalent expressions! Slide 31 Day 4 Task: (E + L) = $6.00 The cook accidently splattered ketchup on this order and therefore doesnt know how many orders of eggs and a large drink to prepare. Working with your partner, use the information that isnt covered in ketchup to help the cook figure out this order. Slide 32 Lets look at some other orders covered in ketchup. With your partner, use what isnt covered to determine what was ordered and/or the number of items ordered. Use the space provided to show your work and/or explain your strategies used. X + = $6.50 G + H = $10.50 + G + B = $5.50 Slide 33 X + = $6.50 G + H = $10.50 + G + B = $5.50 Slide 34 Exit ticket: Create your own order with a ketchup stain. On the back, solve for your missing information. Slide 35 Day 5 Task: Dr. Suess Does Lunch! Find the price to buy two milkshakes. $6.00$6.25 $4.75 ?? Slide 36 Its your lucky day!!! Behind each door is a piece of information that may be helpful. Door 1 Door 2 Door 3 Slide 37 $7.50 Slide 38 $4.50 Slide 39 $8.75
