Students show strategies for finding the sum of eight consecutive numbers.
Here's the patterns they observed from the first eight numbers...
Dear Ms. Toshima,

Some of us have found that the pattern you showed on the show when you
added 8 and 1 , 7 and 2 and 6 and 3 the pattern also works for any series of
odd or even or a mixed series.
Another way we found to add up the numbers was to add up every randome
pair.Then add the numbers from those pairs in an elimination pattern. 1+2=3,
3+4=7, 5+6=11, 7+8=15, then 3+7=10, 11+15=26, then 10+26=36. With this pattern
you can do much larger groups of numbers following the pattern of 3+7 +11+ 15
for each pair.
