Gracie's Challenge (age 9)
- I'm thinking of a two-digit number. The number is a number that you say when you count by 3's, 4's, and 5's. What number am I'm thinking of?
- Find the 8th multiple of six. Then add one. What is the square root of the answer?
Great job, Gracie. You amaze me at your ability to master math concepts. I'm so very proud of you.
