Fractions - 4th grade

I solve two word problems involving mixed numbers: the first has to do with a perimeter of a triangle, and the second has to do with a blueberry muffin recipe (Mathy says YUMMM!). The first part of this lesson is here:

I show how to subtract fractions and mixed numbers (mostly mixed numbers) using a visual model - or just by logical thinking, kind of imagining pie pictures in your mind. In the 2nd part we then solve some word problems:

Here we first practice using the shortcut for multiplying a fraction by a whole number. Then we triple a recipe that has various fractions in it. Mathy wants to add BLUEBERRIES to the recipe, of course! Part 1 of this lesson is here:

I show, using visual models, how to multiply a fraction by a whole number. It is really easy! By the time you've seen me work through several examples, you've probably figured out the shortcut for this yourself.
