Here is the base question: Lily has 3 boxes of crayons. Each box has 8 crayons. How many crayons does Lily have in total? How many would she have if she gave her friend Riley 4 crayons?
Part 1: How many crayons does Lily have in total?
To answer this question, we need to first look at the description.
We know that:
1: Lily has 3 boxes of crayons. [] [] []
2: Each box has 8 crayons inside. [IIIIIIII]
To solve this problem, we must multiply 3 x 8, which equals 24, so Lily has 24 crayons in total. [IIIIIIII] [IIIIIIII] [IIIIIIII]
Part 2: How many would she have if she gave her friend Riley 4 crayons?
In the previous part, we determined Lily had 24 crayons in total. If she gives 4 to Riley, we would need to do 24-4, which equals 20. If Lily gives 4 of her crayons to Riley, she would have 20 crayons left.
