  2. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Review: • Subtract the wholes • Subtract the parts • 3a. Are the denominators the same? • 3b. USE EQUIVALENCE TO MAKE THE DENOMINATORS THE SAME • 4. Subtract the numerators. 2

  3. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Review: 1

  4. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Pose the problem: Chen has started to complete this calculation, but is stuck…. 1 What advice would you give to Chen?

  6. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith New learning Chen could also re-group first… We can see we don’t have enough parts, so we can re-group…

  7. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Practise re-grouping…

  8. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Practise re-grouping…

  9. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Which strategy will you choose? 1. Subtract whole numbers then make an improper fraction to subtract the parts 2. Re-group then subtract whole numbers and parts

  10. Amy Stokell, Natalie Ruddell, Valda Varadinek-Skelton, Vicky Smith Task: Sort the calculations – which ones need to be re-grouped in order to subtract?
