Assistance means the same thing as "giving help" to someone.

The best place for children to grow up is with their families but sometimes families have a hard time and need support to keep their children safe.  Child welfare describes the services provided to families to keep children safe. In many cases, child welfare can provide services to the family so the child can live safely at home but sometimes the child has to live with extended family, friends or a foster parent while their parents address some of the problems they are having.  Young people who live with foster families or in group homes are called "children in care" or "youth in care". 

A convention is a agreement made between countries who decide that they should all do something a certain way.

For example, the UN Convention on the Rights of the Child (UNCRC) is an agreement between the governments of many different countries, who have decided that they want all the children in their countries to have the same basic rights. 

"A declaration is an agreement among countries about a specific issue that requires urgent action. It tells us what governments must do or not do around such an issue.” (p. 5, UNDRIP for Indigenous adolescents)

When something is equitable, it means that things are fair and that things are done in a way that meet different peoples' needs. 

“’Rights’ are things every child should have or be able to do. All children have the same rights. These rights are listed in the UN Convention on the Rights of the Child. Almost every country has agreed to these rights. All the rights are connected to each other, and all are equally important. Sometimes, we have to think about rights in terms of what is the best for children in a situation, and what is critical to life and protection from harm. As you grow, you have more responsibility to make choices and exercise your rights.” (UNCRC in child friendly language)

Its meaning is similar to Aboriginal Peoples, Native Peoples or First Peoples. Indigenous peoples are descendants of the original people or occupants of lands before these lands were taken over or conquered by others. Many indigenous peoples have maintained their traditional cultures and identities (e.g., way of dressing, language and the cultivation of land). Therefore they have a strong and deep connection with their ancestral territories, cultures and identities  (p. 5 UNDRIP for Indigenous Adolescents).

This is the French word for "mixed blood". The Constitution Act of 1982 recognizes Métis as one of the three Aboriginal Peoples. Historically, the term Métis applied to the children of French fur traders and Cree women in the Prairies, of English and Scottish traders, and Dene women in the north, and Inuit and British in Newfoundland and Labrador. Today, the term is used broadly to describe people with mixed First Nations and European ancestry who identify themselves as Métis. Note that Métis organizations in Canada have differing criteria about who qualifies as a Métis person. (NAHO)

“The United Nations (UN) is an international organization founded in 1945 after the Second World War by 51 countries, with headquarters in New York in the United States of America. Today this number has increased to 193 countries. The UN is a platform for countries to discuss and take decisions on a number of important issues. It plays a key role in keeping peace throughout the world and helping governments work together to improve the lives of people who live in their countries. Countries that form part of the UN are called ‘Member States’ and take decisions through the United Nations General Assembly, which is very similar to a world parliament. Sometimes these decisions are documented as declarations.” (p. 5, UNDRIP for Indigenous adolescents)
