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.

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.

6. 20+60+20=100

7. Atharv’s answer is: 32+48+19 = 99

8. 44+44+12=100

Figuring out where to put the answer in here took forever. Still haven’t figured that out, so here it is in the comments. Were we supposed to just write it by hand in his notebook?
