Answer 2

Basically, you are just finding ways to add up to 30 based on 10 groups..the examples you gave are great!

Answer 3

So you have to find the addends that can add up to 30? @JuanitaM

Answer 4

yes...
for instance - you can have 10 groups of 3 people
or you can have 1 group of 21 and 9 groups of 1 person each

see it - they all total up to 30 groups and you can only account for 30 people

Answer 5

How do you get 1 group of 21? @JuanitaM

Answer 6

putting 21 students in 1 group and then 9 groups of 1 person each...totals 10 groups right?

Answer 7

lets say for instance, that I put in 1 group 12 and in the other 9 group I put 2 people each. Is this correct?

How did you get 21 and 9? Are they together?

@JuanitaM

Answer 8

ok...1 + 9 = 10 correct
12 + 18 = 30 correct

yes, your example works

Answer 9

yes 21 and 9 are together

1 group of 21 kids
9 groups of 1 person
10 group and 21+9 = 30 kids
