Look at the pattern below
What number does the pattern start with?
What do we have to do to the first number to get to the second number?
What do we have to do to the second number to get to the third number?
Do we have to do the same thing to each number to get to the next
number?
If the answer is YES, then we have a RULE, which is ….
ADD 1
Now that we know the rule we can EXTEND the
pattern.
Let’s go ONLINE to do work with number patterns.
ADD 2
Let’s EXTEND this pattern using the ADD 2 rule.
WE NOW KNOW….
If we use the ADD 1 rule
We will get this pattern 0 1 2 3 4 5 6 7
AND
If we use the ADD 2 rule
We will get this pattern 0 2 4 6 8 10
We will spend the next few days thinking of more RULES so we
can EXTEND more number patterns and do more SKIP
COUNTING.
