To calculate two times 10, Amelia counted by 10 two times and got 20. Follow Amelia’s method of counting by 10 to calculate 10 times 10.

In this question, we have to calculate 10 multiplied by 10. And we’re told to use Amelia’s method. Amelia counted by 10 two times and got 20. So if we’re going to use Amelia’s method, we need to count by 10. We need to count by 10 10 times because we’re multiplying 10 by 10. So we know that two times 10 is 20. We have to calculate 10 times 10. We don’t need to start from zero because we already know that two times 10 is 20. We just need to keep skip counting by 10 until we reach 10 times 10. Three, four, five, six, seven, eight, nine, 10. 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. 10 multiplied by 10 equals 100.

We calculated our answer using Amelia’s method of skip counting by 10. We skip counted by 10 10 times until we reached 100.
