Subtract Eggs app can help kids to know how to borrow when subtracting , this app use hatch out ducks to help kids understand subtraction.
For example: 82-27 =?
you can follow the steps to do subtraction by regrouping:
1. 2 is less than 7, so we need to regroup 1 ten as 10 ones, drag 1 ten to ones’ blue box.
2. After regroup, there are 7 tens and 12 ones.
3. Drag the eggs to the marked place to hatch out 7 ducks
4. Drag the 2 tens eggs to the marked place to hatch out 20 ducks
5. Check the remaining number of eggs, enter the answer, press the green check button, check the answers
