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

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