# Robert Kaplinsky: Teaching Mathematical Problem-Solving Digitally

### #EduDuctTape S03-E049

• 2 Truths & 1 Lie
• Educational Duct Tape Question: “How do I teach mathematical problem solving digitally?”
• “We are coming from a position where we have always taught it without technology, we should give ourselves a lot of grace.”
• In-N-Out burger question
• Desmos Activity Builder for a real-world problem
• Desmos has pre-built classroom activities, as well as the “Activity Builder” for making your own.
• Use drag-and-drop editing to add content to an interactive slide deck (text boxes, sketches, graphs, etc.)
• Slides can be oneway (providing info to students) or interactive (text questions, drag-and-drop, sketch, card sorts, etc.)
• Can see an overlay view that is similar to what Pear Deck offers
• Teacher.desmos.com
• Desmos Marbleslides
• Desmos can anonymize student names and freeze student screens
• Sliders let students explore elements of problems, patterns, and graphs (for example, changing the m or b in y=mx + b)
• “A lot of the way that we value mathematics in the United States is on getting the right answers quickly and efficiently. As a teacher, I was really good at creating math robots who could get the answers, but really didn’t know what they were talking about.”
•  Focus on real-world problem-solving in mathematics → mathematical modeling
• “It’s easy to enter into, but challenging to master and that, I think, is very satisfying in general.”
• Open Middle Math
• Open Middle with Desmos Activity Builder
• The Dunning-Kruger Effect – “The more that you learn, the more that you realize you don’t know.”
• The Celebration of the Adjacent Possible
• Apple Podcast Review from Jated Bubbsy
• #EduDuctTape Flipgrid Question from Andrew Nikola
• microphones that I mentioned:
• Samson Q2U Handheld Dynamic
• Audio-Technica ATR2100
• Audio-Technica ATR2100x
• Blue Snowball
• Blue Yeti
• Rode
