A recent task I developed used visual models of multiplication involving a unit fraction. Can you match visual models with the expressions ⅓ x 12, ⅓ of 12 or 12 x ⅓? Who would have guessed that creating this task would send me on a hunt through time and continents for the first definitions of multiplication, multiplier, and multiplicand?
With mounting pressures of high stakes testing and pacing guides, often teachers find it difficult to add math writing tasks to daily lessons without leaving something valuable out. According to a study published this year, teachers don’t have to choose. Writing is a superpower when teaching fractions!
In our zest to have children learn math deeply and creatively, professional math educators sometimes give the impression that algorithms are the enemy. In my opinion, nothing could be further from the truth.
