## Why Open Middle?

just when I think my Ss are "good" w/reasoning, the problems show me some holes to fill. I like that. Continuous growth.

My first time trying an @openmiddle problem with my students today. Wasn’t sure how it would go or if they’d solve it. After a few minutes going at it (and coming up with more than one solution) they asked “can we do another one?” “That was fun - we should do it more!” pic.twitter.com/Y8BjbUdH9q

Thanks to @openmiddle for this question to consolidate our learning @MargueriteHCDSB. Grade 7’s are encouraged to challenge family at home to continue their math talk and reasoning beyond school. #hcdsbmath pic.twitter.com/x64VahvqLB

It was an @openmiddle showdown in 5th grade! They could NOT stop! One student even asked me for his paper during recess so he could try to get even closer! #wearegrandview #iteachmath #mtbos #productivestruggle pic.twitter.com/u51e54W7zl

Used an @openmiddle problem to work on finding the largest value for x. Shoutout to @rnhung for introducing me to start with random numbers with Ss to allow them to understand the objective of the problem. The #vnps work was amazing. #iteachmath #mtbos pic.twitter.com/jZ911k1r1y
