SI Tech HS Mathematics Teacher, Ms. Heidi Chu’s #congruence lesson masterfully using #EdTech via a rubric-based peer-review entry ticket, followed by self-recorded triangle videos eliciting steps from students providing #voice, #choice, #mastery assessments & @Flipgrid to share results as an exit ticket. Students used their #oracy skills to articulate their steps and rationalize their choices, while working collaboratively and hands-on via a series of thoughtful inquiry activities. @sibod31 | St
