Subtracting fractions and mixed numbers - video lessons for 4th grade

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.

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!).
