AIM: How can we solve problems that use rational numbers? Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Rational Numbers wksht (found below) Do Now: Josh has a rewards card for a movie theater. he received 15 points for becoming a rewards card holder he earns 3.5 points for each visit to the movie theater he needs at least 55 points to earn a free movie ticket Which inequality can Josh use to determine x, the minimum number of visits he needs to earn his first free movie ticket? A. 55 = 3.5x + 15 C. 55 = 3.5x + 15 B. 55 = 15x + 3.5 D. 55 = 15x + 3.5 Classwork: Students worked on rational number situations individually for an extended period of time. After the designated period, they compared their methods and results with their partner. Excellent discussions were had. We discussed key points of interest and disagreement as a class and shared correct responses. Resources
AIM: How can we solve problems by modeling them with equations? Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Expressions and Equations wksht (found below) Do Now: Ms. Garland bought x number of shirts for the new members of her chorus. The cost for x number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on the purchase. Write and solve an equation to find the number of shirts Ms. Garland bought. Classwork: Students worked on equation and expression situations individually for an extended period of time. After the designated period, they compared their methods and results with their partner. Excellent discussions were had. We discussed key points of interest and disagreement as a class and shared correct responses. Resources
AIM: How can we use original and new amounts to find percentages of unknown amounts
Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Do Now: What percent of the car price is tax? What percent of the restaurant bill is tip? What percent of the shirt cost is the discount? Classwork: Students worked with their partner on three focal problems involving percent. The situations required students to determine the percent of an amount. Partners compared their work and analyzed methods. In another activity, students were given problems with insufficient information. They needed to ask for specific information from a partner holding (and not showing) a data card. Once the necessary information was gathered, they solved and analyzed the solution. Resources AIM: How can we solve problems with percent increase or decrease? Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Percent Increase/Decrease HW (found below) Do Now: Jeanette purchased a concert ticket on a web site. The original price of the ticket was $75. She used a coupon code to receive a 20% discount. The web site applied a 10% service fee to the discounted price. Jeanette's ticket was less than the original price by what percent? Classwork: Students continued working with percent situations. They expressed percent increase and decrease problems with percent equations. Students identified, matched, and wrote equations for a variety of realworld contexts. Resources
AIM: How can we use percent to describe increases or decreases? Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Percent Increase/Decrease wksht 2 HW (found below) Do Now: What do you notice? What do you wonder? Classwork: We use double number lines to solve problems with percent increase and decrease. Students used additional methods from previous lessons to connect to the visual representation. Resources
AIM: How can we use percent to describe increases or decreases? Announcements: The NYS Math Assessment for 7th Grade will be May 12. Please begin your preparations now. HW: Percent Increase/Decrease HW (found below) Do Now: Here are the scores from 3 different sports teams from their last 2 games. {table with sports points} 1. What do you notice about the teams’ scores? What do you wonder? 2. Which team improved the most? Explain your reasoning. Classwork: Imagine that it takes Andre 3/4 more than the time it takes Jada to get to school. Then we know that Andre's time is 1 3/4 or 1.75 times Jada's time. We can also describe this in terms of percentages: We say that Andre's time is 75% more than Jada's time. We can also see that Andre's time is 175% of Jada's time. In general, the terms percent increase and percent decrease describe an increase or decrease in a quantity as a percentage of the starting amount. Resources
AIM: How can we involve problems involving scale drawings? Announcements: The NYS Math Assessment for 7th Grade will be May 46. Please begin your preparations now. HW: Scale Drawing Homework 2(found below) Do Now: The scale drawing of a field in the shape of a triangle is shown below. [1 unit = 2 meters]  Triangle with base of 7 units, and height of 5 units not shown What is the actual area, in square meters, of the field? Classwork: Scale drawings are twodimensional representations of actual objects or places. Floor plans and maps are some examples of scale drawings. On a scale drawing: Every part corresponds to something in the actual object. Lengths on the drawing are enlarged or reduced by the same scale factor. A scale tells us how actual measurements are represented on the drawing. For example, if a map has a scale of “1 inch to 5 miles” then a 1/2inch line segment on that map would represent an actual distance of 2.5 miles Sometimes the scale is shown as a segment on the drawing itself. Because a scale drawing is twodimensional, some aspects of the threedimensional object are not represented. For example, this scale drawing of a stop sign does not show the thickness of the stop sign. A scale drawing may not show every detail of the actual object; however, the features that are shown correspond to the actual object and follow the specified scale. Resources
AIM: How can we involve problems involving scale drawings? Announcements: The NYS Math Assessment for 7th Grade will be May 46. Please begin your preparations now. HW: Scale Drawing Homework (found below) Do Now: The circumference of a circle is 25 (pi) feet. What is the area, in square feet, of the circle? Leave your answer in terms of (pi) .
