Build Cube Trains to Solve Addition Word Problems - Sums up to 10
š Choo choo! Time to build number trains! We can use linking cubes like train cars to solve math stories.
Concept
Addition word problems are stories with hidden numbers. Drawing pictures or using blocks makes these stories easy to understand! šÆ **How to Build a Cube Train:** When you join two groups together, you can make a cube train! **Story:** "Mia has 4 red cubes. Leo gives her 3 blue cubes. How many cubes does Mia have in all?" 1. **Build the first part:** Line up 4 red blocks. 2. **Build the second part:** Line up 3 blue blocks right next to them. 3. **Snap them together!** 4. **Count the whole train:** You have 7 blocks total. **Sentence:** 4 + 3 = 7. Using different colors helps you see the "parts" that make the "whole".
