Maths Wall Challenge

For today we did a challenge for maths and it was about picking a 3 digit number and
do different problems with the same number like making 100 or number sentences it is to make drifferent kinds of ways to get the number for a example : let try to get up to 802 400+400+2=802 and keep going it was easy but cound't do it very fast .  Some of the problems weren't confusing and back to the learning is making expanded maths sentences and writing the number in words for making to hundred and I maybe to a thousand .
