In my last post, some of the videos were not loading properly so I have since discovered a method to change the video format – thanks to my Regional Math Team lead Cathy Campbell for sharing the conversion site! They all should be up and running smoothly now- although some are slow to load!

This week we continue with exploring our personal strategies in my classroom. Upon review I am once again in awe of some of the methods that seem to be working for my students.

On one review question students were asked to show a minimum of 3 ways they could approach the multiplication sentence of 6 x 7.

Some of their approaches are listed below.

6 x 7 = n so I think of 7 x 7 = 49 – 7 = 42.

6 x 7 = n I think of 6 x 10 – (6 x 3) = 60 – 18 = 42

6 x 7 = n I think of 2 x 7 three times 2 x 7 = 14 x 3 = 42

6 x 7 = n I think of 3 x 7 = 21 and I double it so 21 + 21 = 42

6 x 7 = n I think of 5 x 7 = 35 and then I have to add 1 more sets of 7 on so 35 + 7 = 42

The following videos show clips of my students working using their personal strategies to solve equations.

## About musingsofamathteacher

I am presently employed at New Sarepta Elementary School as a grade five teacher. During my career I have taught Grades 12 - 2. The past three years I was fortunate to work part-time as Math Lead for my school district, Black Gold Regional Schools, and have just recently accepted a part-time secondment with Edmonton Regional Learning Consortium. I have always had a passion for mathematics and am excited about implementing Alberta's "new" mathematics curriculum.
