Both metric and customary systems are utilized. Problems dealing with length, weight, and capacity are solved. The concept of precision is explored, in addition to solving problems related to data. These ideas are applied to scale drawing and scale models. Distance problems are solved, and finally percent problems are addressed throught the use of proportions.
Students learn the relationship of percent to decimals and fractions.
They learn to compute a percent of a number, what percent one number is of another, and to determine a number from a know percent. Percents are estimated and multiple-step problems are solved. The concepts of perimeter, area, circumference, surface area, and volume are addressed. In conclusion, the students make tables and use formulas to determine the volume and area of geometric figures. Students gather their own data, organize it by drawing statistical plots and graphs, and summarize a set of data.
