1. 49 + 32 + 18 = 99

2. Our answer was 29+18+53=100

3. I had a lot of fun with this challenge and passed it along to my family when I couldn’t figure it out! Looking for more of these challenges in the future!

4. 23+56+18=100

If I can get my students with behaviors to do this at 3 or upper I will challenge them to do this during morning warmup.

• 23+56+18=97 not 100. It’s close though You might has meant 24+57+19=100

5. One of my classes came up with 42+38+19. It was great to see them put together the tens first, then they added all of the ones, and finally added the ones and tens for the final answer.
