The fact family shows the relationships between the three numbers involved.<br \/>\nIn an addition and subtraction fact family, there are four addition and subtraction sentences created using three numbers. Similarly, in a multiplication and division fact family, there are multiplication and division sentences created using three numbers.<\/p>\n<p>We can use fact families to reinforce or learn the connection between addition and subtraction, and to help learners memorize the basic addition & subtraction facts.<\/p>\n<p>There are two types of fact families: an addition\/subtraction family and a multiplication\/division family.[\/vc_column_text][vc_column_text el_class=”headingnew”]Rules[\/vc_column_text][vc_column_text]- All 3 numbers in a fact family are related.<br \/>\n– They are the only numbers that can be used.<br \/>\n– There are 2 addition facts and 2 subtraction facts in each fact family.<br \/>\n– The addition facts end with the greatest number.<br \/>\n– The subtraction facts begin with the greatest number.<br \/>\n– The greatest number is always written at the top corner of the triangle.[\/vc_column_text][vc_column_text el_class=”headingnew”]Example[\/vc_column_text][vc_column_text]<span style=\"color: #16a085;\"><strong>Complete the fact triangle using fact family.<\/strong><\/span><br \/>\n<a href=\"https:\/\/en.oryxlearning.com\/question\/maths\/2nd-grade\/fact-families\"><img loading=\"lazy\" class=\"alignnone wp-image-5163 size-full\" src=\"https:\/\/oryxlearning.com\/learn\/wp-content\/uploads\/2021\/11\/1-17.png\" alt=\"\" width=\"204\" height=\"181\" \/><\/a>[\/vc_column_text][vc_column_text el_class=”headingnew”]Solution[\/vc_column_text][vc_column_text]We know from the rules that the greatest number is always written at the top corner of the triangle.<br \/>\nTherefore the greatest number here is 19.<\/p>\n<p>We have to find the number that adds to 9 and makes 19.
