Acc7.9 Putting It All Together
In this optional unit, students use concepts and skills from previous units to solve four groups of problems. In the first group of lessons, they consider tessellations of the plane, understanding and using the terms “tessellation” and “regular tessellation” in their work, and using properties of shapes (for example, the sum of the interior angles of a quadrilateral is 360 degrees) to make inferences about regular tessellations. In the next group of lessons, students calculate and estimate quantities associated with running a restaurant. They use their knowledge of proportional relationships, survey findings, and scale drawings to determine the number of calories in one serving of a recipe, the expected number of customers served per day, or the floor space needed in the restaurant. Students then estimate quantities such as age in hours and minutes or number of times their hearts have beaten, using measurement conversions and consider the accuracy of their estimates. In the last group of lessons, they investigate relationships of temperature and latitude, climate, season, cloud cover, or time of day. In particular, they use scatter plots and lines of best fit to investigate the question of modeling temperature as a function of latitude.Read More
