Subitizing to Foster Multiplicative Thinking

Learning basic facts through tricks or a mnemonic song lead students down a path of memorization, not understanding.  I previously discussed the idea of conceptual development here.  When students practice their multiplication facts, they’re expected to move from concrete to abstract … Continue reading

Take a Math Trick and Make it Bleed

I hate math tricks and avoid them at all costs. Tina Cardone and many members of #MTBOS are huge advocates of conceptual learning which is how we became blessed with this gem. There’s no denying that students love tricks, especially the … Continue reading

What The Fluency?!?!? Time to stop the debate

After reading Dr. Boaler’s post on timed tests and math anxiety http://joboaler.com/timed-tests-and-the-development-of-math-anxiety/, I can’t help but think about the amount of harm we are causing. To automatize? Or to memorize?  That is the question!  But should there even be a … Continue reading
