An economical way to write and illustrate all fact families for a given factor. Students illustrate dot arrays and write out the equations in verbal sentences as well as numerical equations.
Pages are included to do this for 4 and 8, and an identical set of pages for copying, on which you can specify the factor with which you’d like your students to work.
The activity opens with a discussion of arrays, and places where students can find and describe examples of arrays in the classroom. This is intended for students who are starting to use arrays for multiplication to find examples of arrays in the real world.
There is also a set of pages for students to complete fact families, given one of the four equations. A 2-sided set of pages is left blank for you to fill in one equation in each fact family and copy for your class.
