These pupils had a pack of twenty cards numbered from 1 to 20.They arranged the cards into six unequal piles.
The numbers on the cards in each pile added to the same total.
What is the total and how could this be done?
(To work this out, you will need to use the cards numbered 1 - 20 which are kept in the teacher's pen pots in your classrooms.)
1+19=20
ReplyDelete2+18=20
3+17=20
4+16=20
5+15=20
10+10=20
Jason that's times tables to 20
DeleteYou have six piles of numbers Jason and they all equal the same amount, but have you used all the numbers from 1 to 20?
Delete19+1=20
ReplyDelete10+10=20
18+2=20
13+7=20
10+7+2+9+6+12=40

Alexia and Anis, you have not put all the numbers into 6 piles.
DeleteWhen I put it in six piles it was very difficult and two were remaining on the floor, and I could put them into 3 groups so that's why there were two remaining.
Delete8 and 7 are in the incorrect places and some do not add up to some numbers. 7+18=25 8+17=25.
ReplyDeleteThe 7 is not supposed to be after the 8 so it goes 12345678910 not 12345687910
ReplyDeleteWell spotted Tamari and Ellie, but you have not answered the question. You should put the numbers 1 to 20 into 6 piles. Each pile of numbers must add up to the same amount.
DeleteYear 4, to help answer this question you should use the cards numbered 1 to 20 in your classroom.
ReplyDeleteToday you said don't need the cards 1-20
DeleteIf you notice the 1 is on top of the 11 and it keeps. Going on but the 8 is in the rong place if. It switch is back it will be like this 7 then 8. When it is the rite order it will look like this 123456(78)910.
ReplyDeleteYes, but have you tried to solve the problem Jahvon?
DeleteMr Highman, what shall we do to solve these cards but I know eight and seven are in the wrong place.
ReplyDeleteHere is a tip Deborah. First take a whiteboard and try addition followed by division.
DeleteThe total is 35 of every unequal pile. How we irked it We added 1 to 20 and we got the answer 210. Then we divided by six and it equals 35 so that is the answer.
ReplyDeleteYou are nearly there Fathia and Jayanna. Now take the cards numbered one to 20, split them into six piles. Remember all of them must equal 35.
ReplyDeleteIn My first pile there are 18 and 17
DeleteThe next pile there are 19 and 16
The next one in my pile is 20 and 15
Next one is in the pile is 14,13,5 and 3
The 5th pile is 10,12,9 and 4
The 6th pile is 2876111 2,8,7,6,1 and 11
Has someone finally found the answer? Is Jayanna right Year 4?
Deleteyes sir Jayanna is right.
Delete12x12=144

10x10=100
100x100=1000
