Look at the subtraction problem below.
Do you need to regroup to subtract the ones?https://talkandcomment.com/p/bb7f3619af76f7842910448c (voice note)
Yes, because you can't subtract 9 from 2. https://talkandcomment.com/p/bdb5b1e16b46cc4d7fa97f93 (voice note)
No, because 2 minus 9 equals 7. https://talkandcomment.com/p/b35a6a7a1505a1cdb0e54a7d (voice note)
Yes, because regrouping is fun. https://talkandcomment.com/p/6f8ff2eec1612e3f30a6b975 (voice note)
No, because I do not like to regroup. https://talkandcomment.com/p/88fb17c416be6ddae6eca5f4 (voice note)
