- Complete each family of facts. Children see three numbers and finish four equations. It matches the homework question “complete each family of facts”.
- Write the four facts. A full triangle is given and children write every fact themselves. This is the fullest test of the idea.
- Fact family house. The same task, drawn as a house with the whole in the roof.
- Blank triangle or house. Children choose their own three numbers and write the family. It works as a free fact family template.
