Weeks Nine/Ten (November 1-12) The main focus for this week will be addressing Number Sense 1.2 one of the Key Standards for the seventh grade as well as several Mathematical Reasoning Key Standards. November 11 - Veteran's Day Holiday || November 12 - Non-Student Day Main Activity Interactive Mathematics Text         p. 44 Mountain Bike            This activity includes analyzing data and using mathematical tools and reasoning to defend responses. Spreadsheet Activity - suggestions on how to use Claris Works spreadsheet files are included in this activity. Alignment to CA Mathematics Standards: Number Sense 1.2 add, subtract, multiply and divide rational numbers, integers, fractions and decimals and take rational numbers to whole number powers Mathematical Reasoning 1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, identifying missing information, sequencing and prioritizing information, and observing patterns 1.2 formulate and justify mathematical conjectures based upon a general description of the mathematical question or problem posed 2.8 make precise calculations and check the validity of the results from the context of the problem Extensions MAC Text         pp. 90-123 - Statistics and Data Analysis         pp. 470-471 - Circle Graphs Alignment to CA Mathematics Standards: Statistics, Data Analysis and Probability 1.1 know various forms of display for data sets, including a stem-and-leaf plot or box-and-whisker plot; use them to display a single set of data or compare two sets of data 1.2 represent two numerical variables on a scatter plot and informally describe how the data points are distributed and whether there is an apparent relationship between the two variables (e.g., time spent on homework and grade level)ß Read and interpret tally charts 1.3 understand the meaning of and be able to compute the minimum, the lower quartile, the median, the upper quartile and the maximum of a data set Problem of the Week - pp. 66-72 - Unit 8 - data         On the first Wednesday of the month students will have a reading activity in class. They will read the different POWs in their text and select one to work on for that week. Alignment to CA Mathematics Standards: Mathematical Reasoning 1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, identifying missing information, sequencing and prioritizing information and observing patterns. 1.2 formulate and justify mathematical conjectures based upon a general description of the mathematical question or problem posed. 1.3 determine when and how to break a problem into simpler parts. 2.4 make and test conjectures using both inductive and deductive reasoning 2.5 use a variety of methods such as words, numbers, symbols, charts, graphs, tables, diagrams and models to explain mathematical reasoning. 2.6 express the solution clearly and logically using appropriate mathematical notation and terms and clear language, and support solutions with evidence, in both verbal and symbolic work. 3.1 evaluate the reasonableness of the solution in the context of the original situation 3.2 note method of deriving the solution and demonstrate conceptual understanding of the derivation by solving similar problems. Resources Assessment Students will complete a written report showing how they analyzed data and made conclusions using reasoning skills. Students will make graphs and charts to display data. Students will use correctly the terms: mean, mode, range, minimum, lower quartile, median, upper quartile and maximum. Weeks Eleven/Twelve (November 15-26) The main focus for this week will be addressing Number Sense 1.2 one of the Key Standards for the seventh grade as well as several Mathematical Reasoning Key Standards. November 25-26 - Thanksgiving Holiday Main Activity Interactive Mathematics Text         p. 17 That's Sum Triangle            This activity includes calculating sums and using mathematical reasoning in a setting using triangles. Alignment to CA Mathematics Standards: Number Sense 1.2 add, subtract, multiply and divide rational numbers, integers, fractions and decimals and take rational numbers to whole number powers Mathematical Reasoning 1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, identifying missing information, sequencing and prioritizing information, and observing patterns 1.2 formulate and justify mathematical conjectures based upon a general description of the mathematical question or problem posed 2.1 use estimation to verify the reasonableness of calculated results 2.2 apply strategies and results from simpler problems to more complex problems 2.4 make and test conjectures using both inductive and deductive reasoning 2.6 express the solution clearly and logically using appropriate mathematical notation and terms and clear language, and support solutions with evidence, in both verbal and symbolic work Extensions MAC Text         p. 233 - arithmetic vocabulary         p. 204-206 - properties of addition         p. 8-10 - using rounding Alignment to CA Mathematics Standards: Number Sense 1.2 add, subtract, multiply and divide rational numbers, integers, fractions and decimals and take rational numbers to whole number powers Resources Assessment Students will explain the strategies that can be used to solve the arithmetical problem involving sums.
