Skip-Counting – The Threes & Sixes, Plus a Game

Today's post winds up our "From the Trenches" series by Colorado classroom teacher and former Yellin Center Learning Specialist Beth Guadagni. In Beth's prior posts, she explained how our brains learn math facts and how she uses songs to help her students -- all of whom have dyslexia -- learn the fours multiplication facts.

Our last post gave background and instructions for teaching multiplication facts for four and eight. Using different songs, Beth explains how the same techniques can be used to teach the math facts for threes and sixes.

Skip-Counting by Threes
“Three” is repeated three times to get the rhythm to work out. We add “and thirty-six” at the end in the same way people add “and many more” to the “Happy Birthday” song. Jazz hands, while optional, are highly recommended.

Row,                   row,                      row                      your                     boat,

Three,                 three,                   three,                   six,                        nine


Gently                down                    the                       stream,

Twelve,               fifteen,                   eighteen                        

Merrily,             merrily,                   merrily,                 merrily,

Twenty-one                 Twenty-four                   Twenty-seven


Life is but a dream.

Thirty   thirty-three

…and thirty-siiiiix!

Game: Domino Draw

Purpose:
To give students practice applying skip-counting sequences to real math problems.

Materials for the game:
A set of dominos, turned face-down or in a bag.

Procedure:
If you don’t plan to play long enough to go through a whole set of dominos, use a timer so that students play for a set amount of time. Be sure, once it goes off, that everyone has had the same number of turns.

There are two variations here.

1. To target the sequence students are learning:
On his turn, each player draws a domino at random. He adds the number of dots on the domino, then multiplies that number by the sequence you’ve been practicing. For example, if his domino had 11 dots on it and you were practicing the threes, he’d get a product of 33 and earn 33 points.

2. Once students have learned all the sequences, try this variation:
On her turn, each player draws two dominos at random. She adds the number of dots on each domino, then multiplies them together. For example, if one domino had four dots on it and the other had twelve, she’d get a product of 48 and earn 48 points.
