One of the possibilities are 9,5,5,1 The second one 1,4,13,2. The other one is 10,4,5,1. The fourth one is 10,4,3,3 the fifth one is 6,9,3,2 The sixth one is 4,8,4,4 And the last one is 9,7,3,1.

I think that there is many different ways to make 16 by using numbers from 1-8 but it I think that is all the calculations I can make to get the number 16.

One possible way could be 6,7,4 and 3.These four nunbers add up to 20.

ReplyDeleteAnother way is 2+4+5+9.I calculated 2+4=6+5=11+9=20

ReplyDeleteAnother way is 7+3+2+8=20.I just try to find number bonds to 20 and use it to find out some possibilities

ReplyDeleteSuper idea Ruqayya. This is an excellent example of how knowledge of number bonds can help you solve problems.

DeleteYou can also do 1+8=9+7+4=20

ReplyDeleteI did 5+3=8+6=13+7=20

ReplyDeleteI calculated 6+3=9+7=16+4=20

ReplyDeleteI also found 8+3=11+5=16+4=20

ReplyDeleteI also did 6+7=13+5=18+2=20

ReplyDeleteI had found all 7 possibilities.If I can do it so can you.

ReplyDeleteIndeed!

DeleteI had tried the challenge and had gotten 16. I did 7+5=12+4=16

ReplyDeleteI also did 8+2+5+1=16

ReplyDeleteI tried the challenge and calculated 3+4+7+2=16

ReplyDelete9+1+6+4=20

ReplyDelete6+4+8+2=20

2+4+6+8=20

1+7+4+8=20

All I did was pick 2 number's in between 1-8 and I added them together, then I took the number away from 20.

One other way is 7+3+2+8

ReplyDeleteA possibility could be 4+3=7+5=12+8=20

ReplyDeleteAnother possibility is 8+2+4=14+6=20

ReplyDeleteSome of the possibilities could be

ReplyDelete4+6+8+2=20

8+7+2+3=20

4+5+8+3=20

1+6+5+8=20

2+4=6

ReplyDelete6+5=11

11+8=19

19+1=20

6x4 so the numbers that you have to count in must be in fours.

ReplyDeleteHere are all 7 ways

ReplyDelete1.8+2+9+1

2.7+3+4+6

3.5+8+6+1

4.7+5+4+1

5.9+1+7+3

6.8+7+4+1

7.9+7+3+1

Those are all the ways.

6+6+5+3=20

ReplyDeleteanother way is 16+4=20 or 18+2=20 or 17+3=20 or 15+5=20 or 19+1=20 or just try number can to 20.

ReplyDeleteOne way is 10,5,3,2

ReplyDeleteAnother way is 9,5,4,2

Another way is 10,4,5,1

For the challenge

10,4,2

7,5,4

9,4,3

These are all the combinations:

ReplyDelete1.8+5+4+3=20

2.5+6+8+1=20

3.4+8+2+6=20

4.4+5+7+4=20

5.8+7+4+1=20

6.4+5+6+5=20

Challenge:4+5+7=16

19+1

ReplyDelete16+4

10+10

21-1

One of the possibilities are 9,5,5,1 The second one 1,4,13,2. The other one is 10,4,5,1. The fourth one is 10,4,3,3 the fifth one is 6,9,3,2

ReplyDeleteThe sixth one is 4,8,4,4 And the last one is 9,7,3,1.

The fifth different ways can be:

ReplyDelete9+8=17+3=20

9+9=18+2=20

10+5=15+2=17+3=20

9+6=15+1=16+4=20

10+4=14+1=15+2=17+2=19+1=20

I've found many different ways but I just want to show you this one which is:

ReplyDelete6+6+6+2=20

I think that the challenge could be:

ReplyDelete8+8=16

8+5=13+3=16

9+3=12+4=16

I think that there is many different ways to make 16 by using numbers from 1-8 but it I think that is all the calculations I can make to get the number 16.

Armarnie,make sure you remember it's cards from 1-8

Delete6x4=24-4=20

ReplyDelete5+6=11+4=15+3=18+2=20
