All decimal skills, excluding converting repeating decimals to fractions, are adequately covered with commendable emphasis on the properties. Negative decimals are not presented in a lesson since integers come after decimals in the book. The word problems are appropriate and varied. A wise teacher will remove the calculator option in most cases. This chapter is well done.
Simple interest is covered later in the book than most percent-related topics.
This material could use a few more word problems. The chapter covering most of this topic progresses smoothly and clearly from ratios, to unit rates, to proportions with variables and on to cross multiplying. In the chapter that largely deals with fractions, there is a nice section on changing units within the customary system for lengths and volumes. The properties of equality are clearly stated with arithmetical and variable examples, although inequalities are not covered. This is all good.
