Mastering the words

Vocabulary is an essential part of learning a language. The more words your child knows, the better they can express themselves and understand others. A wide vocabulary is therefore not only important when reading, but also in understanding other teaching material and in terms of social skills. WoordExtra by Squla is free to use for any child that wants to improve their vocabulary.

Every child proficient in language with WoordExtra

Most children in the Netherlands start primary education with a vocabulary of 1.000 to 3.000 words. But there are also toddlers who only know 200 to 300 Dutch words. Or older children who are just starting to learn the Dutch language. The 2.000 words that children should know can be practised on WoordExtra. This list was made by the Institute for Dutch Language Education (ITTA).

For who is WoordExtra?

WoordExtra is meant for children between the ages of 3 and 6 who need more support in improving their vocabulary. This could be children who grow up in linguistically deprived families or in families with a migration background, but also for any child that finds language difficult and wants to improve. With WoordExtra they can playfully get introduced to the 2.000 Dutch words that children in the third grade should know.
