Place Value Disks
This set of soft, foam, color-coded place value disks helps math students to master place values and mathematical operations up to the millions. The set contains 280 numbered disks, forty each of ones to millions. These place value manipulatives support core math curriculums such as Singapore Math® and more. Disks measure 1" in diameter. ~ Mike
Colorful counters for mastering math! Each disk is assigned a color according to place value for easy recognition. Group the numbers together to visually track progress as you practice addition and subtraction. Includes 280 disks, 40 of each from the ones to millions places. Supports Singapore and Eureka Math. Disks measure 1" in diameter.
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 SingaporeMath.com 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 SingaporeMath.com. 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.
These colorful foam disks make learning place value easier for the visual or tactile learner. Place values from 1 to 1,000,000 are represented in 7 value sets and values from 1-1000 are represented in 4 value sets. Each place value is a different color, which makes them easy to differentiate. These disks are used in several of the Singapore Approach books.

It's hard to get more basic - and solid - than this program. The no-nonsense black and white worksheet format might deceive you, but fight it! They are engaging, with straight-forward teaching instructions (concept, introduction with manipulatives, how to use page) at the bottom of each. The scope and sequence is similar to Singapore's Earlybird Math and designed to prepare the student for Primary Math. It can be used as a supplement to Earlybird or as a stand-alone program. Many household items are used as manipulatives, but the few specific ones suggested are listed below (balance and pattern blocks are only referred to a very few times). ~ Janice
