So, I am reflecting on my approach. I realize that I can't go on with this approach of self-directed (Montessori-style) discovery learning with manipulatives. I need to entice them into the joy of fractions, so I went shopping looking for a food item that I can use to divide into fractions. Soft chocolate chip cookies? Too small and crumbly. Tortillas for quesadillas? Too much trouble. Bread? Not even on all sides. Red vines? Yes! So I will try red vines, and less independence, and see if I can decrease the frustration for both them and me.
How about this for a song? (Mulberry Bush)
This is way we add fractions
With unlike
Denominators.
We need to find equivalent fractions
So that they both have
Common denominators.
Find common multiples
And use the
Least of them.
You can use the Identity property
To multiply
The fraction in question.
Two over two, three over three
Whatever you need
To get common denominators.
Add only the numerators,
The denominator stays the same.
Don't forget simplest form
Divide with common factors
Number over number
How do you know it's simplest form?
When the greatest common factor
Is one.
