Adding fractions with denominators that are multiples of the same number

Hi, wondering if someone could help me find a video that shows the teaching using arrays to add fracrtions with denominators that are multiples of the same number. I cannot seem to find itand it was on the NCETM site when I last saw it about three weeks ago. I want to put it on a cacluation policy currently being developed for staff to use to support their teaching of it. Thank you

Arrays are great for representing multiplication and division but are not used for addition or subtraction. It’s best to circular representations of fractions (pizzas) and/or proportion bars for this.
