Love this #AmplifyClassroom kindergarten activity! First the octopus checks sums of 8 then the sea urchin comes out. Great job. I’ve been wary about making my kids not hate math (no drill n kill) and they’re asking can we do math on the computer before bed. Yes! Cc @ddmeyer

After an audible groan b/c the activity was paused, Ss made sense of ordered pairs through a purposeful #AmplifyClassroom experience! This S pair wrote without any prompting. Great collaboration and learning in 5th grade today!
