Amelia found 30 shells at the beach. Victoria found 20. How many more did Amelia find?

The question tells us that Amelia had 30 shells and Victoria had 20. We need to work out how many more shells did Amelia have than Victoria. To do this, we need to find the difference between 30 and 20. We can use a place value chart to help us calculate 30 take away 20. Zero take away zero is zero, and three tens take away two tens makes one ten. 30 take away 20 is 10. Amelia found 10 more shells than Victoria.
