Answer :
Certainly! Let's find out how many children are in the math club using two different methods to make a ten.
### Method 1: Direct Addition
1. We start with 8 boys.
2. Then, we add the 7 girls.
3. So, we simply add the two numbers directly:
[tex]\[ 8 + 7 = 15 \][/tex]
Thus, the total number of children in the math club is 15.
### Method 2: Making a Ten
1. Again, we start with 8 boys.
2. We can split the number 7 into two parts to help make a ten. Notice that 7 can be split as 2 and 5 because:
[tex]\[ 7 = 2 + 5 \][/tex]
3. Now, we add 8 and 2 first, which makes a ten:
[tex]\[ 8 + 2 = 10 \][/tex]
4. Next, we add the remaining 5 to the ten:
[tex]\[ 10 + 5 = 15 \][/tex]
Thus, by making a ten first, we also find that the total number of children in the math club is 15.
Both methods confirm that there are 15 children in all in the math club.
