What is Sudoku and what skills can we learn from playing it?AIM: Enjoy Winter Break!HW:Do Now:a) List games that you have played that involve numbers. b) Are there any math skills that you've learned by playing these games? We learned how to play Sudoku in class today. The common misconception is that Sudoku is a game that requires calculations. In fact, Sudoku is a puzzle game that requires reasoning above all else. Players must be able to Classwork: why numbers must go in their locations. This type of thinking is necessary to be successful in middle school math and beyond.prove
How can we find percents of amounts in a restaurant setting?AIM: Finish Restaurant Group Assignment packetHW: Michelle and her 3 friends went out to eat. Each person ordered $14.25 worth of food. They ordered and all shared the "chocolate volcano" for $8.95. How much is the subtotal?Do Now:Ans. $14.25 x 4 = $57.00 $57.00 + 8.95 = $65.95 We continued working on our Restaurant Group Activity packet today. We reviewed the rubric attached to the assignment so students were aware of what they needed to do to receive maximum credit. Students worked cooperatively with their group members to verify calculations and bounce ideas around for the written portion of the assignment. Any loose ends were tied.Classwork: How can we find percents of amounts in a restaurant setting?AIM: HW-07: Finish #1 in restaurant group assignment packetHW: You and a friend are dining at a restaurant. The bill has a subtotal of $38. The service was great so you decide to leave a 20% tip and split the total cost evenly. How much should each person pay?Do Now:Ans. $38.00 x .20 = $7.60 Food + Tip = Total Amount $38.00 + $7.60 = $45.60 $45.60 / 2 = $22.80 We applied percent problems in the context of a restaurant setting. Students were placed in groups up to 4 and were tasked with deciding which neighborhood restaurant they would like to eat at: Santa Fe (Southwest/Mexican fare), TGI Friday's (American fare), Salvatore's of Soho (Italian fare). After they decided, students received menus from their desired restaurant. Classwork:As per the directions in the Restaurant Group Assignment packet, each student ordered one appetizer, one entree, one dessert item, and one beverage. All items from the group were recorded on each packet. Students then followed prompts from the packet to complete questions involving tax, tip, and discount.
How can we find percents of amounts?AIM: Enjoy the weekendHW:Do Now:A shirt is regularly priced at $20. It is on sale for 30% off. If the NYC sales tax is 8.875%, how much will the shirt cost after the discount, tax included? Today was a continuation of finding percents of amounts. We learned another approach that doesn't require the use of proportions. Students learned that if they want to find the percent of an amount, they can convert the percent to a decimal (by moving the decimal two places to the left) and then multiply that decimal by the amount they are trying to find the percent of. Classwork:Example: $180.00 item is 40% off. How much is the discount? ---> 40% = .40 ----> 180 x .40 = $72. The discount is $72. We practiced several scenarios using this new shortcut method. We practiced applying it in the context of tax, tip, and discount. Resources: How can we use assess our proportional reasoning understanding?AIM: Review class notes on percent, tax, discount, tax, tip, markupHW:Do Now:After your homework is checked, please clear your desk of everything except for a pencil, calculator, and ruler. Classwork:Unit 3 Quiz 2
How can we use practice constant of proportionality related questions?AIM: Prepare for tomorrow's quizHW:Do Now:Jeff runs a third of a mile in a fourth of an hour. At that rate, how far does he run in two and a half hours? Classwork:The vast majority of the 7th grade was on the Liberty Science Center field trip. Students who attended class used materials to prepare for tomorrow's quiz. How can we use proportions to find percents of amounts?AIM: Percents, Tax, Tip, Discounts Word Problem WorksheetHW:Do Now:A pair of sneakers cost $85. They are on sale for $15 off. How much do the sneakers cost after the discount? Answer: $70 ($85-$15) : AnnouncementPlease prepare for your Constant of Proportionality quiz on Thursday (12/17/15). Use the resources below to aid in your preparation. Topics for the quiz will include: Unit rate (from a table, graph, and equation), determining if a relationship between two variables is proportional (from a table, rate, or equation), writing equation from tables, and plotting a relationship on a coordinate plane from a table or equation. Classwork:Today's Do Now tapped prior knowledge related to discounts being subtracted from original prices. After reviewing answers to the previous night's homework, we discussed the idea of sales as a technique to get consumers to buy more products. Giving the holiday season has begun, students are exposed to prime examples both online and in physical retail stores daily. We investigated two situations: a jacket being sold online that was originally $180 for 40% off and a pair of sneakers originally priced at $124.99 being discounted 20%. Students used percent proportions to determine discounts and subtract them from the original prices to find the sale price. We extended the idea of using proportions to find percents of numbers (as our AIM suggests) to idea of tips at restaurants, and other services. Students saw that unlike in discounts where we subtract the amount, tips are added to the starting amount. Resources:Please use these online resources to supplement your preparation for Thursday's quiz on proportional relationships. Students should review their classnotes, recent vocabulary words, and homework to improve the likeliness of success.

The ticket cost $60, plus $4 in sales tax. How much did the ticket cost in all?Do Now:Ans: $64 ($60+$4) : Please prepare for your Constant of Proportionality quiz on Thursday (12/17/15).Announcement We began today's lesson with an open discussion on the concept of tax, more specifically: Why is tax important? Where does the money go? How is it collected? What gets taxed? We went to NYC's department of finance webpage to investigate the different tax rates for products/services in NYC. We used Classwork:percent proportions to calculate tax amounts for various commonly purchased products. We also discussed common methods in which people earn an income: salary, commission, and hourly. We related each of these to the business idea of markup and how every business exists to make make money and therefore must charge customers a markup on products in order to make a profit.Resources:Part/Whole = %/100, where Whole is the amount of the item(s) and the Part is the portion of the whole (in this case, tax). How can we find a unit rate in a description, equation, table, or graph?AIM: NoneHW: The following graph shows the number of muffins that can be made with different amounts of flour.Do Now:1. What is the unit rate? 2. How many muffins can be made with 2.5 cups of flour. : Please stop by during lunch hours when you have any questions on classwork or homework. Announcement After discussing the Do Now and various methods to answer each question, we returned the group quiz and had an opportunity to see our mistakes. Students then had opportunities to ask more questions on specific questions. We reviewed the homework about Grandma's Cookie Recipe to further our understanding on constant of proportionality/unit rates in tables, equations, and graphs..Classwork: How can we find a unit rate in a description, equation, or table?AIM: Cookie Task Worksheet (Proportional Reasoning Task)HW: Which graph(s) are proportional? Explain your reasoning. Do Now:: Please stop by during lunch hours when you have any questions on classwork or homework. Announcement We continued using our knowledge of unit rate to build rate tables and then graph the relationships on the coordinate plane. Students were assigned a cookie task in which they use proportional reasoning to do what we modeled in class.Classwork: |
