Mazie’s Amazing Marshmellows (Lesson 2 of 2)

Launch/Hook:

Demonstrate on the board what happens when we have more pieces of something than the total in regards to fractions.

Use yesterday’s task as an example: What is the fraction if somebody orders the equivalent of one whole slab, but broken up into packs of 6?

It would look like 24/6 as an Improper Fraction if we are talking about 6 packs of marshmallows. We can divide 24 nicely into 6, so it would be 4 full boxes, but what if it was boxes of 9? 

That would be 24/9 which ends up being 2 whole boxes of 9, and one more box that is 6/9 full. So that would be what we call a Mixed Number. It has a whole number of 2, and a fraction of 6/9, written as 2 6/9

Task:

Your problem today, is that we have had some corporate orders for marshmallows, and they are for certain amounts of individual pieces in specific sized boxes.

You will need to work out what the Improper Fraction and the Mixed Number representations of full boxes are used for each order:

20 pieces in boxes of three

27 pieces in boxes of four

44 pieces in boxes of six

50 pieces in boxes of nine

70 pieces in boxes of twelve

100 pieces in boxes of twenty four

Students are specifically asked what the numerator and denominator are, and what that means for each answer, when going through answers on the board.
