To solve this problem, we need to calculate the total number of pizza slices and then determine how many children can be fed if each child gets one slice.

Step 1: Calculate the total number of slices

• Mirriam made 5 pizzas.
• Each pizza is cut into 8 triangular pieces.

So, the total number of slices is: $5 \times 8 = 40 \text{ slices}$

Step 2: Determine the number of children

• If each child gets one slice, the total number of children that can be fed is equal to the total number of slices.

Therefore, Mirriam can feed: $40 \text{ children}$

So, 40 children can be fed.

5 Additional Questions:

1. What if each child could take two slices of pizza? How many children could be fed then?
2. How would the number of children change if Mirriam made 10 pizzas instead of 5?
3. If each pizza had been cut into 6 pieces instead, how many children could be fed?
4. How can you calculate the total number of slices if different pizzas are cut into different numbers of slices?
5. What if Mirriam wanted to reserve some slices for herself? How would that affect the number of children she could feed?

Tip: When dealing with problems that involve equal distribution, dividing the total amount by the number of units each person gets is a helpful approach.
