SKIP-COUNTING A valuable skill at any level Ms. Hancock 2010 SKIP-COUNTING Often taught in the latter part of First Grade and through possibly the Third Grade. In higher grades multiplication is taught in its place. Both are sound, valid skills necessary for students to be successful in school and life. WHAT HAPPENS TO SKIP-COUNTING? Why do we stop teaching and using skip-counting in our classrooms? Is it . . . Because once a student learns multiplication it becomes a skill no longer necessary for one’s toolkit? Because students always hated skip-counting by anything other than 2’s, 5’s, 10’s, and 25’s? or is it . . . Because we as teachers forget the value of the skill in light of TAKS (STAAR) requirements? Because we’ve always done it that way? WHY DOES SKIP-COUNTING REMAIN A VALUABLE TOOL? First, and foremost, it keeps our minds active and flexible. If students are using their brains, they’re less apt to get themselves into trouble. Keeping one’s mind flexible may aid in encouraging creativity. May help stave off the onset of Alzheimer's or ameliorate the symptoms. It can be fun to see how far you can get before stumbling. WHY DOES SKIP-COUNTING REMAIN A VALUABLE TOOL? It can be used in a variety of places. Grocery store – everything is not a multiple of the same price. You might have 3 items at $2.60 and 2 items at 1.50: $2.60…$5.20…$7.80…$9.30…$10.80 /or/ $2.60 times 3 = $7.80; $1.50 times 2 = $3.00; $7.80 plus $3.00 = $10.80. Both arrive at the same answer, but in the first example each item is handled only once. WHY DOES SKIP-COUNTING REMAIN A VALUABLE TOOL? It can be used for a variety of reasons . . . The only thing that changes is the starting place. Start at 2 and count by 2’s: 2, 4, 6, 8, 10, 12, 14 . . . . Start at 3 and count by 2’s: 3, 5, 7, 9, 11,13, 15 . . . . Start at -0- and count by 13’s: 13, 26, 39, 52, 65 . . . . Start at 266 and count by 7’s: 273, 280, 287, 294 . . . . etc. WHAT WE KNOW . . .
