Solve Two-Step Whole-Number Problems

How the lesson starts: Solve Two-Step Whole-Number Problems

1. Milo's lemonade stand

   Hi there! Milo runs a lemonade stand. He has 18 lemons. He finds 7 more under the tree, then uses 5 for lemonade. How many are left? That's two steps. Let's go!

2. Step by step

   Start at 18 lemons. Step 1: Milo finds 7 more. Hop up 7 to 25. Step 2: he uses 5. Hop back 5 from 25. You land on 20! So 20 lemons are left.

3. Let's count Milo's cups

   Milo has 34 cups, gets 15 more, then uses 12. How many are left? Step 1: 34 + 15 = 49 cups. Step 2: 49 − 12 = 37 cups. Watch out: 49 is only halfway. Don't stop after step 1!
