This guide covers essential topics for the Georgia CRCT test, including surface area, volume, and area formulas for triangles, rectangles, and circles. Students will complete warm-up problems in their notebooks and prepare for vocabulary tests. Key concepts explored include three-dimensional shapes, cross-sections, and scale factors. Detailed instructions encourage careful reading of problems, estimation of relationships between scale factors and area, and use of scratch paper for calculations. Complete exercises found on specified workbook pages to reinforce learning.

Area formulas • Triangle ½ base times height • Rectangle Length times width • Circle ∏ times radius squared
Original figures • Triangle base = 6 height = 8 • Rectangle length = 6 width = 4 • Circle diameter = 4
Apply these scale factors to the triangle, rectangle, and circle to create 2 images of each SF = 4 SF = 8 Calculate the area’s of the original and all the images. Set up ratios to show the relationship between the SF and the area of each. (eq the SF is 4, the area increases by ?) Workbook pages 34 and 33
