New Manipulatives

The following pictures represent manipulatives designed by Dr. Stix that can be ordered through the Cuisenaire Company of America.

 

Andi Stix’s math lab where manipulatives are developed for the Cuisenaire Company of America and where in-classroom instruction is tested and refined in the public sector.

1. Algecans

Algecans are manipulative tiles and chips that use the concept of a balance to teach children introductory algebra. The materials include one balance, 25 two-color variable cans, and 25 two-color counter chips.

 


 

Picture Grids

2. Picture Grids

Picture Grids for Fractions and Decimals provides a new way to understand equivalence and fractional computation. The grids are especially helpful to visualizing multiplication and division. Place two grids at perpendicular angles and the product at their intersection is easy for students to see immediately. Contains 60 acetate squares, each showing a particular fractional amount. Color coded by family, the grids show halves, thirds, fourths, fifths, sixths, eighths, tenths, and twelfths. Also included are two hundredths grids. One set is good for up to 4 students working together. Ideal for the overhead projector.

 


 

Picture Pi

3. Picture Pi

Unlock the secret of pi as students rotate special acrylic disks to observe why pi equals approximately 3.14. The set comes with two different sized, thick acrylic disks so that students can test and retest their estimations.

 


 

Time

4. Fraction Ring: Time

The fraction ring for time helps students develop mental images of measurement as fractional parts of a circle, as it relates to time. The clear plastic ring fits the Fraction Circle manipulatives.

 


 

Decimals

5. Fraction Ring: Decimals

The fraction ring for decimals helps students develop mental images of measurement as fractional parts of a circle, as it relates to decimals, percent, base ten and money. The manipulative helps students create a circle graph with ease. The clear plastic ring fits the Fraction Circle manipulatives.

 


 

Degrees

6. Fraction Ring: Degrees

The fraction ring for degrees helps students develop mental images of measurement as fractional parts of a circle; as it relates to acute, obtuse, right, and reflective angles. The clear plastic ring fits the Fraction Circle manipulatives.

 


 

Set

7. Fraction Ring: Set

The set of three fraction rings consists of a time, decimal, and degree ring. With this set, students can see the relationship between one-quarter, 25 cents, 90 degrees, and 15 minutes. This set can be purchased with or without the Fraction Circle pieces.

 


 

Set

8. Squares and Square Roots

Squares and Square Roots can be taught visually by using three different colored manipulatives from the base ten sets. Each set can accommodate numbers up to 600. For larger numbers, as shown in the picture, use additional sets. Each set contains 5 hundred flats, 36 ten rods, and 81 unit cubes.
