BreakApart Multiplication
 Pick the times table you want to practice: 0x to 10x.
 Use the strategy given by the rhyme to multiply.
 Instead of memorizing your times tables, you’ll be using “partial products” to multiply quickly.
 Each strategy also teaches factors – not just facts.
 Later, use this strategy to multiply doubledigit and larger numbers too.
BreakApart Division
Partitive
“Sharing” strategy – think of the divisor as the number of groups or parts.
Quotative
“Grouping” or “Measurement” strategy – think of the divisor as the size of each group.
Partials
Don’t divide a large number all at once, break it into smaller parts that are easier to divide.
