What Are Mixed Operations?
Mixed operations mean using different math operations together in one problem!
Sometimes you'll need to add and subtract, or multiply and divide all in the same problem. The key is knowing which operation to do first and following the rules of math.
Remember PEMDAS!
1️⃣ Parentheses first
2️⃣ Exponents (we'll learn these later!)
3️⃣ Multiplication and Division (from left to right)
4️⃣ Addition and Subtraction (from left to right)
Let's Practice Together!
Example 1: The Pizza Party Problem
You have 3 pizzas with 8 slices each. Your friends eat 15 slices. How many slices are left?
Let's break it down:
First, we multiply to find total slices: \(3 \times 8 = 24\)
Then we subtract the eaten slices: \(24 - 15 = 9\)
There are 9 slices left! 🍕
Example 2: The School Supplies Challenge
You buy 5 packs of pencils with 10 pencils each, and 3 packs of erasers with 6 erasers each. How many items did you buy in total?
Let's solve it step by step:
First, calculate pencils: \(5 \times 10 = 50\)
Then calculate erasers: \(3 \times 6 = 18\)
Finally, add them together: \(50 + 18 = 68\)
You bought 68 items in total! ✏️
Parent Tips 🌟
- Make it real: Use everyday situations like shopping or cooking to practice mixed operations ("If we need 3 eggs per cake and want to make 4 cakes, but we only have 8 eggs, how many more do we need?").
- Step by step: Encourage your child to solve one operation at a time and write down each step to avoid confusion.
- Game time: Play board games that involve multiple operations like Monopoly Junior or create your own math challenge cards.
