In #MathsToday (yesterday) my #MHF4U students were having trouble determining the leading coefficient of a polynomial in factored form so I gave them this series to do in random groups at the whiteboards. It was quick and worked really well.

A series of equations of polynomials from a quadratic in standard form to a degree 6 polynomial in factored form: y = 0.5(5-x)(x-1)^2(2x+8)^3 where one thing is changed at a time to make each one a little more challenging than the previous one

For those of you who were using Seesaw for student portfolios/feedback/SBG, what’s the new alternative platform (now that Seesaw doesn’t allow individual teacher accounts for multiple classes)? #iteachmath #mtbos
