Amy has 12 eggs. She needs 6 eggs for one recipe, and 8 for another recipe. How many more eggs will Amy need to buy to have enough for both recipes?
Explain what you did and why you did each step.
Step 1:
Why?
Step 2:
Why?
She ___________ have enough eggs for both recipes.
Step 1: Add both recipe's eggs: 6+8=14
Explanation: this gives us the total number of eggs she needs.
Step 2: Take away the needed eggs from the eggs she has. 14-12=2
Explanation: This equation shows the eggs she needs, taking away the eggs she has. Since there are two left over, this means that she needs more eggs, or she does NOT have enough for both recipes.

Jenny and Tom have the same number of M&M's. Jenny has 14 red M&M's and 12 blue M&M's. Tom has 16 red M&M's and some blue ones. How many blue M&M's does Tom have?
1. First,
2. Then,
3. Next,
4. Last,
First, I think about what I know. They have the same number of M&M's and I am looking for how many blue M&M's Tom has because that is what the question asks and it says "some".
Then, because I know both of Jenny's numbers, I can add them together to see how many she has. 14+12=26 This tells me that Tom will also have a total of 26 M&M's since they have the same number.
Next I need to find Tom's blue M&M's with a missing part equation. I know his total and his red M&M's, so I subtract 26-16=10.
Finally, I write my answer and what it means. Tom has 10 blue M&M's. I know I am correct because I can check my work by adding 16+10=26.
