Even numbers can be made into two-row arrays, but odd numbers cannot - there being always one item left over. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows. University of Cambridge. Another approach to discovering factors of numbers is to begin with a particular whole number and make as many different rectangular arrays as possible - see the. Number Lines & Place-Value Charts Slideshow. Say: Show 3 groups of 5 counters. With the help of certified and current classroom teachers, TeacherVision creates and vets classroom resources that are accurate, timely, and reflect what teachers need to best support their students. Ask students to circle one even number and one odd number between 20 and 50 on thier charts. and see if there is an odd man out. A hundreds chart is used to show the alternating pattern of odd and even numbers, and students are asked to extend the pattern to identify additional odd and even numbers. Further explain that if there is an unpaired counter, or a counter is left over, then the number is odd. If you divide 0 by number 2, the result is always 0 and is corresponding to the definition of an even number, no remainder if divided by the number 2. One way to improve the readability of large tables is to color alternating rows.

Another investigation of factors using arrays is the search for numbers that can form square arrays; namely, the square numbers .

This representation not only assists in understanding the process, but provides a visual image for Two-sided counters can be used to model one-to-one correspondence, addition and subtraction, or skip-count.
