1. You can draw, work backward and make a table.

2. You start at 10 because it will be 11 cards in one pile the most. There are 4 pile, so 11 times 4 equals 44. If it’s from 13, the most in one pile will be 14 cards. The total will be higher than 44.

3. I use the drawing technique to solve the problem.

4. Yes, the 4 pile is going to be 44 cards, If one pile ends at a 9, that meanings there’s 2 cards at that pile. You add nine cards to make the pile 11 cards in total. 11 times 4 equals 44. The 44th card that you pick.

5. The picture grabs my attentions.
