Supporting the transition from informal to formal acting, Jegro caters to the market with curriculum support materials for primary schools adapted to the educational needs for children aged 6-12 years. The Jegro educational products provide insight in subjects in the scope of mathematics and language, moving the child from cognitively to concrete, pictorial and abstract representations.

Categories of the Jegro curriculum:

Jegro divides learning of mathematics in four stages:

Stage 1: informal acting
The first stage reality is represented with daily life manipulatives. The accent is on importance for children to start learning mathematics through real-life situations. This may be counting everything they see in the world around them, such as fruit, toy cars, blocks, dolls, crayons, plates and balloons.

Stage 2: represent concrete
The second stage is represented with use of realistic models. Most often this is a concrete representation of items surrounding them in daily life quantified by sliding the same number of beads on a counting frame. This simulates the one to one correspondence and links the action of sliding the beads whilst naming the values shown by counting out loud.

Stage 3: represent abstract
The third stage is representing reality by using abstract models. Children are stimulated to recognize and to use the number symbols 5 and 10 as an anchor whilst counting. Use of these structures which represent a number of items can be done more easy and efficient than one by one counting.

Stage 4: formal acting
The fourth stage is representing performing of formal operations and to explain those verbally. This helps children to use mental models. For example, instead of sliding beads on a counting frame, the transition to abstract reasoning is made by just observing.

The Jegro manipulatives are purposeful to any developmental level, with their application in the educational sphere meaning:

– Pupils are engaged in learning by the provision of challenging yet unambiguous materials making formal concepts accessible
– The concrete, hands-on materials fully in line with the explicit abstract concept appearing in mathematics books are specifically designed to support primary school curriculum
– Materials produced in both a teacher and similar student version allows simultaneous execution throughout demonstration of a concept in a classroom
– Pupils ratiocinate their skills by continuous practice, exemplified in a varied and pleasant manner, leading to a substantial understanding of mathematics

The Jegro language materials are focused on further development of communication skills as well as expending vocabulary. Building upon the skills learned up to the age of 6, the child’s capacity of noticing differences and detecting similarities is also expanded.

History of Jegro

Having its roots as a manufacturer of fine wood work, producer of equipment for dairy farmers and sports articles shops, Jegro is founded by Mr. J. Groeneveld in 1913 in Bolsward, a town in the north of the Netherlands.

Following the sale of a set of rewarding stamps to a primary teacher, the Noord Nederlandsche Stempelfabriek is founded in 1948 in the northern Netherlands province Groningen by Mr. J. Koopman and the company starts producing stamps and other educational products.

Jegro starts cooperating with professor Idenburg and Dr. P. Post of the University of Amsterdam. This collaboration results in the development and production of the first educational materials by the brand.

During the sixties Jegro sets out its dedication to further develop and manufacture high quality educational materials and to this day the brand has firmly rooted itself worldwide as a well-known, respected and acknowledged creator thereof.

During the course of 1960 to 1962, also the Noord Nederlandsche Stempelfabriek expands its brand by extending its production of stamps and other educational materials. This period also elevates the brand to an international one as Mr. Koopman starts exporting his products to Belgium, Germany and U.S.A. as a result of attending international teaching aid fairs.

In 2009 Jegro and the Noord Nederlandsche Stempelfabriek decide to join forces and continue together under the brand name Stempelfabriek & Jegro. This allowed the new brand to offer a full and complementary range of educational materials, and in addition, they started producing custom made products destined for the primary education market.

Heutink acquires Stempelfabriek & Jegro, with the latter becoming their fourth brand, resulting in the formation of Heutink International. Jegro continues existing as a brand, but, depending on their target group age, the former Stempelfabriek products are merged into either the Educo or Jegro brand assortment.

Keeping in tradition with the former Stempelfabriek brand, Jegro materials are to this day still mainly produced in Groningen, the Netherlands, by the Noord Nederlandse Stempel- en Leermiddelenfabriek (NNSL). An international producer of customized wood products, stamps and additional materials, craftsmanship is the NNSL trademark.
