Choose one of these numbers: 2,3,5, or 6. Double the number you chose and then double the sum. Keep doubling until you get a sum that is greater than 1,000. How close to 1,000 is the number you reached.
Record a number pattern sequence that is at least 10 terms long where each number is three less than the previous number. Here’s an example: 79 76 73 70 67 64 61 58 55 52
Roll 2 dice to make a 2-digit number. Round the number you make to the nearest 10. Record and repeat 10 times. Explain your strategy for rounding to the nearest 10.

6 12 24 48 96 192 384 768 1,536
I did it all in my head, and my mom is proud of me.
Yay! Hope you feel proud of you too. That is a lot of mental math and great calculations!
Thanks, I really put my effort in to it.

It’s interesting to see the even odd pattern of the numbers.
Thank you for sharing.
