## Reflection: Quizzes Subtraction Quiz: Algorithms, Estimation & Word Problems - Section 3: Administering the quiz

I got what I had hoped for! 94% of my students achieved 90% or above on this quiz! Students wrote well and explained their work and understanding of word problems. The practice in writing about math from the beginning of the year is starting to prove itself now. I was very pleased. I shared a couple samples on this Educreations Video.

Well done!
