This is an organizer where students will try to find the number 3 a new home. The houses on the street have large numbers on them, and the student must color the square part of the houses red if they are multiples of the factor three. Then, students must determine which houses are multiples of the factors 3 and 5, so number three can have its friend number 5 over for a visit in a house where they will both feel comfortable. This organizer can support your study of factors or multiples, or both. It depends on your focus.
