REPEATING PATTERNS
Where the attributes are repeated in some
manner. i.e., red burst, red burst, white
burst, red burst, red burst, white burst,…
Denoted by an AAB AAB …
GROWING PATTERNS
‘Sequences’ whereby there is growth in
the number of items from one set to the
next. This helps to develop an algebraic
understanding.
NUMBER PATTERNS
Many patterns are observed with
numbers:
Give the next three items in the pattern and
provide the rule (try to do so in algebraic terms):
3, 6, 9, 12,…
1, 4, 9, 16, …
23, 11, 5, 2, …
2, 6, 12, 20, 30, …
PATTERNING
Using: blocks, beads,
pasta, stamps, colours,
people, cards, etc.
(Millie’s Math House (bing and bong) , Mathville Kidway
(crane, movie))
Using hundred boards
Using calculators
Using music, dance…

PATTERNING PROCESS
• Copy a pattern using one attribute
• (Copy a pattern using more than one
attributes)
• Extend a pattern using one attribute
• (Extend a pattern using more than one
attributes)
• Create a pattern using one attribute
• (Create a pattern using more than one
attributes)
• Transferring a pattern from one form to
another
ATTRIBUTE BLOCKS
• MAKE A CHAIN OF THE BLOCKS
WHEREBY EACH SUBSEQUENT
BLOCK CHANGES BY ONE ATTRIBUTE
ONLY…
• NOW TWO ATTRIBUTES
• NOW THREE ATRIBUTES

COME OUT AND PLAY WITH ME
AND BRING YOUR DOLLY’S THREE,
CLIMB UP MY APPLE TREE.
SLIDE DOWN MY RAINBOW
INTO MY CELLAR DOOR
AND WE’LL BE JOLLY FRIENDS
FOR EVERMORE, MORE, MORE, MORE, MORE

1/1 = 1.00
1/2 = 0.50
1/3 = 0.33
1/4 = 0.25
1/5 = 0.20
1/6 = 0.167
1/7 = 0.142857 TRY 2/7 AND 3/7 AND 4/7…
1/8 = 0.125
1/9 = 0.111 TRY 2/9 AND 3/9 AND 4/9…
1/10= 0.10
1/11= 0.0909 TRY 2/11 AND 3/11 AND 4/11
TRY FOR ALL NUMBERS FROM 12- 19 ON A CHART
MYSTERIOUS 7’S
1/7 = 0.142857
2/7 = 0.285714
3/7 = 0.428571
Based upon the pattern above, determine:
4/7 =
5/7 =
6/7 =
Consecutive odd numbers

1+3=
1+3+5=
1+3+5+7=
Predict the next three sums.
Consecutive odd numbers

13 15 17 19
21 23 25 27 29
Add the horizontal rows. What do you notice?
What if you use consecutive even numbers?
1. Grab a calculator.
2. Key in the first three digits of your phone
number (NOT the area code)
3. Multiply by 80
4. Add 1
5. Multiply by 250
6. Add the last 4 digits of your phone number
7. Add the last 4 digits of your phone number
again.
8. Subtract 250
9. Divide number by 2
Do you recognize the answer?
CRAZY CUPS!
