Product Description:

Math facts can be learned in a number of ways, but can be difficult for some youngsters. This set includes number bond cards for addition and subtraction and part-whole cards. The cards measure 5 inches square and are made of sturdy, glossy cardstock. There are a few blank cards in each set for making your own combinations.

The number bond cards (80 in the set) are more than flash cards; they show the relationship between addition and subtraction facts. The front of each card presents a diagram with 3 boxes: one box is outlined with a dotted line. The dot-outlined box shows the sum of the other two boxes; the dot-outlined box might instead show one of the addends. The digits you see can be used to explain both the functions of addition and subtraction. The reverse side of the number bond cards show the same diagram as the front, but the dot-outlined number is missing; children name the missing number.

Part-whole cards (80 cards in the set) show the parts of the whole number. The top half of the card shows the larger number and the bottom half of the card shows the numbers used to make the larger number (for example, 4 and 5 at the bottom and 9 at the top); the cards represent combinations up to 10. The back of each card shows the same number combinations, but one number is missing: children determine the missing number.

Help your children learn their math facts but also understand the relationship between functions with these helpful card sets. ~ Donna

Category Description for Singapore Math Programs:

Countries around the world first became interested in Singapore's math curriculum when results of the Third International Math and Science Study (TIMSS) were published in 1995. Conducted by the International Study Center at Boston College, achievement tests in both math and science were administered to students in over 40 countries. Students from Singapore ranked highly in mathematics achievement: 1st in the fourth, seventh, and eighth grade levels and 2nd at the third grade level. Results for the U.S. were disappointing: 10th in the third grade, 11th in the fourth grade, 23rd in the seventh grade, and 27th at the eighth grade level. In a follow-up study in 1999, Singapore again ranked 1st in eighth grade math achievement while U.S. eighth graders ranked 19th. Although a first place ranking does not necessarily imply the best program, something about Singapore's math program seems to be working.

"Singapore Approach Math" is a general term referring to the math curriculum, or syllabus, designed by Singapore's Ministry of Education. The curriculum has been regularly revised over the last two decades, with most recent revisions in 2001. We carry two different lines. From we carry Earlybird Kindergarten Math (PK-K), Primary Math (1-6), and New Elementary Math (7-10). From Great Source Educational we carry Math in Focus (K-6).

Both of these programs are produced by the same company, Marshall Cavendish Education (Singapore). The U.S. Primary Math editions have a 2003 copyright, while the newer, Standards Edition have a 2008 copyright. These are both modifications of the original edition of Singapore math. These programs are distributed in the U.S. by They are essentially the same, though the Standards Edition has a small amount of added material and some of the sequences have been rearranged to better meet U.S. standards. Math in Focus has a 2009 copyright. It is distributed in the U.S by Great Source, a division of Houghton Mifflin Harcourt, and packaged for the homeschool community by Saxon Homeschool. So, the programs have common origins.

Primary Math and New Elementary Math are based on the 1997 mathematics syllabus. New Elementary Math has since been "phased out" of schools in Singapore (probably in favor of texts following the 2001 syllabus). However, Primary Math and New Elementary Math are the series that originally gained Singapore international recognition for excellence in mathematics.

There are now manipulatives especially designed to be used with the Singapore approach. Look for these at the end of this section.
