For example, given the following series of numbers: 7, 10, 13, 16, students might be asked to identify the next two numbers in the series or describe what mathematical &#8220;rule&#8221; is creating the pattern (in this case, the rule is &#8220;adding 3&#8221;). So I figured this was a perfect opportunity to teach the students in Ms. Boone&#8217;s class at Chamberlayne Elementary about spreadsheets and formulas.  I gave them a Numbers template that you can download by clicking here (I just adjusted the size of the cells and fonts). I told them to enter any 2-digit number into cell B2.  Then in cell C2 we wrote a formula &#8220;=B2 + 3&#8221; and pressed the Enter key.  The answer automatically appeared in the cell.  Then I showed them how they could click in the cell and drag the little dot in the lower right corner to fill in the neighboring cells and create a pattern.  Next they wrote the rule in the box.  We continued in a similar manner writing formulas for subtraction, multiplication (use *), and division (use \/).  Once the students understood how to write formulas, I let them write a formula of their own.  Then a partner had to enter a number and see what the &#8220;secret&#8221; formula did to that number.  Their goal was to try to identify the formula or rule that was creating the pattern.  Some students discovered that certain numbers (like 0 or 1) were very helpful in figuring it out!   <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Third graders (and students in other grades as well) are often asked to identify patterns in a series of numbers.
