The basic concepts of this revised curriculum (3rd edition, 2011) are much the same as in the former version (2nd edition, 1991). However, this revision provides improved Bible tone, offers more variety in artwork, and gives more drill in some weak areas. Complete practice sheet sets are available for the revised curriculum, eliminating the need for extensive copying.
The major differences are:
•Art changed to reflect Bible stories or the warmth of Christian family life as opposed to stylized animal theme. This makes themed "carrier" concept less prominent.
•The "zero" is taught as "nothing" and as a placeholder. A first grader is no longer taught to starting counting at zero or to number 100-block grid as 0-99. Rather, we comply with standardized math manipulatives by having a 10-by-10 grid contain 100 squares.
•Fractions have more teaching. The denominator concept is taught first: halves, thirds, and fourths. The numerator concept is also taught in the last quarter of the year; distinguishing between or or two thirds, and between one, two, or three fourths.
•Place value is taught with quantative association instead of a fictional carrier: one crayon, one box of ten crayons, one case of ten boxes.
•Practice Sheets are provided as a complete set. Permission is given to copy them just like the blacklines could be. The Practice Sheets are categorized as: Strengtheners; Required; or, Challenge (fun).
Other than that, the coverage, flow, and academic content have been little altered.
