Sentence Starters for Math Writing:

Example: We are learning about multiplying 2 digit by 2 digit numbers.  First you multiply the ones times the ones, carry any tens, and record the ones.  Next you multiply the ones times the tens, add the carries, and record this in front of the ones in the first row. Then you multiply the tens times the ones, carry any hundreds and record the tens and ones.  (Hint the ones will always be zero for this step.) Then you multiply the tens times the tens, add any carries, and record this in front of the tens and ones. After that you add the two rows to get your answer.  (After explaining in words you could add a number example.)
