Comparing: How Many More?
āļø Who has more? And exactly *how many* more? We can compare two groups by lining them up to easily spot the extras!
Concept
"How many more?" is a question about the **difference** between two numbers. šÆ **The Matching Strategy:** Let's find out how many more 7 is than 4. 1. **Show the First Group:** Draw 7 circles: šµšµšµšµšµšµšµ 2. **Show the Second Group:** Draw 4 circles right below it: š”š”š”š” 3. **Match Them Up:** Imagine lines connecting partners from the top group to the bottom group. 4. **Count the Extras:** Count how many circles in the bigger group do NOT have a partner. * There are 3 blue circles left over. 5. **The Answer:** So, 7 is **3 more** than 4. The subtraction sentence for this comparison is **7 - 4 = 3**.
