Reply To: Lesson 2 – Building A Continuum Of Measurement – Discussion

[marianne aamodt]

I used the Math Learning Center apps and copied and pasted into my reply. Sadly the fraction strips I used did not show up when i submitted my reply so I edited with no pictures. (BTW it’d be really great if you could create a “redo” button for the replies. Sometimes, I accidentally delete stuff and have to retype it!)

Gr. 7 question:

5/8 – 1/2

Direct comparison: Place 2 fraction strips, of the same length, showing 1/2 and 5/8 side by side. Notice which strip’s coloured spaces is longer.

Indirect comparison: hmmm… I didn’t know what to put here. I played with pattern blocks – which don’t work at all as they do not have “eighths” – and number lines.

direct measurement : Place the strips over top of each other . Note that 5/8 is an 1/8 bigger than 1/2

Indirect measurement; we can see that 1/2 = 4/8 so…

5/8 – 1/2 = ____

5/8 – 4/8 = 1/8

This process was much more difficult than I anticipated. Thanks for taking me out of my comfort zone. I am sure the synapses in my brain are firing like crazy. Hope they are creating a pathway for all my new learning!!

But seriously, what should I use for the indirect comparison?
