Mathematics
Vienna reviewed scale drawings by converting drawing measurements into actual lengths, including fractional inch measurements, across four correctly completed problems. She calculated scale factors of 1 1/2, 3/4, and 4 for similar figures and understood that a scale factor below 1 represented a shrinking figure. Vienna also solved a two-step redraw problem by finding the real-world length from a 3-inch drawing at 1 inch = 8 feet, then determining its new drawing length at 1 inch = 6 feet. Her reasoning with the 3/4-inch drawbridge showed strong fraction understanding in context, while abstract fraction notation remained her current growth area.
Tips
Tips: Continue connecting abstract fractions to visual and practical models, such as folding paper strips, measuring objects, and drawing scale plans. Ask Vienna to explain why a scale factor greater than 1 enlarges a figure and why a factor less than 1 shrinks it. A short daily routine could include one fraction notation problem, one scale-drawing conversion, and one explanation in words or pictures. She could also design a simple floor plan or bridge drawing, label its scale, and have someone check her calculations.
