1. Pick any number on the clock face and then find the number opposite to it.
2. Then find the difference between the two numbers. For example, if you choose 1, then 7 is opposite. The difference between 1 and 7 is 6.
3. Do the same with a different number. What happens this time?
Record a couple of examples. Are you able to explain why this happens?
12-6=6 8-2=6 11-5=6 9-3=5
ReplyDelete11-5=6 10-4=6 9-3=6 8-2=6 7-1=6
ReplyDeleteThe answer is always 6 because the number that takes away gives the number to get to 6
12 past 9 is 12 - 9 = 3 because you need to do the example and then takeaway 12 and 9.
ReplyDelete8-2=6 3-9=6 it all makes in different Sumer
ReplyDelete12 past 9 is 12 - 9 = 3 because you need to do the example and then takeaway 12 and 9.
ReplyDelete7-1=6 10-3=6 6-0=6 15-9=6 4+2=6 12-5=6
ReplyDeleteIf you + and - your sum will be 6.
12-5=6 10-3=6 6+0=6 6-0=6 7-1=6
ReplyDeleteIf you + and - you sum time get six.
12 and 6 9 and 3 7 and 1 10 and 4
ReplyDelete12-6=6. I know that 12-6=6 because half of twelve is 6 and 6+6=12
ReplyDelete11-7=4. I know 11-7=4 because 4+7=11
9-3=6 12-6=6 10-4=6 8-2=6
ReplyDelete12-6=6. I know that 12-6=6 because half of twelve is 6 and 6+6=12
ReplyDelete11-7=4. I know 11-7=4 because 4+7=11
Have another look Chennell. Is 11 opposite 7? Have another go explaining why the answer is always the same.
Delete7-1=6
ReplyDelete8-2=6
9-3=6
10-4=6
All of these are 6 because on the clock the numbers are opposite.
Great examples Akeemat. Have another a go at explaining why the answer is always 6. Why might that be?
Delete12-6=6
Delete8-2=6
7-1=6
10-4=6
9-3=6
12-6=6 9-3=6 10-4=6
ReplyDeleteI know because all you have to do is look at the numbers which one is opposite and take away and you will get the answer
