## Mathematics 7th Grade (2nd semester)

Course Description\nMathematics 7th Grade teaches skills essential to adult life and lays the groundwork for future mathematics courses. Students learn to apply their work with rational numbers and integers to everyday situations. Students convert words to expressions and vice versa, using equations and inequalities as problem-solving tools. They compute tax, percentage of error, commission, and interest by using rates, ratios, and proportions; graph ordered pairs; and graph and write linear equations. Their work with simple figures – triangles, angles, circles, quadrilaterals, and polygons – focuses on finding areas and perimeters. Students then move on to scale drawings and composite figures composed of simple figures, and compute the volumes and surface areas of solids, including prisms, cylinders, pyramids, cones, and spheres. Students collect data and use graphs, charts, and diagrams to read, interpret, and display the data. They also learn how graphs can be misleading. Students apply the study of sampling and populations to applications involving probability, likely and unlikely outcomes, permutations, combinations, and compound events. Students then represent these concepts by using Venn diagrams and charts, tools they will encounter in other courses.\n\nCourse Breakdown\n\n Rate of change\n Direct variation\n Proportionality and equations\n Measuring angles\n Types of angles\n Line and angle relationships\n Congruent figures\n Similar figures\n Scale drawings\n Indirect measurement\n Classifying triangles\n Areas of triangles\n Similar triangles\n Congruent triangles\n Circles\n Area and circumference of a circle\n Quadrilaterals\n Polygons\n Composite figures\n Surface areas of prisms and cylinders Surface areas of pyramids and cones\n Volumes of prisms, cylinders, pyramids, and cones\n Spheres\n Similar solids\n Line of best fit\n Central tendency\n Variation\n Stem-and-leaf plots\n Histograms\n Box-and-whisker plots\n Populations and samples\n Sampling methods\n Probability\n Permutations and combinations\n Compound events\n Venn diagrams\n Independent and dependent events\n\nCourse Goals\n Identify types of angles and their measures.\n Determine whether two figures are similar by creating proportions.\n Construct proportions to find the measures of figures drawn to scale.\n Calculate the areas and circumferences of circles.
