Journaling with Fractions

Write a Fraction Fairy Tale.

Red Riding Hood loved to bake. She heard that Three Little Pigs had moved in a new brick house just down the street. Being a good neighbor, Red wanted to welcome the Pigs into the neighborhood. So, she baked an apple pie. When the pie was freshly out of the oven, she put it in her basket and skipped down the street. When she got to the Pigs’ home, the Three Little Pigs were very excited about the pie, but couldn’t decide who would be the Pig to eat it. Red knew that the pie would have to be cut and to keep the Pigs from fussing, she cut it into three equal pieces. Each pig ate 1/3 of the apple pie and lived happily ever after!

Fraction FajitasUse tortillas as a manipulative to teach fractions. Each student will

need two tortillas– one to represent the

whole and one to represent the

fraction.

Mrs. Housley’s Peculiar Pizzas

Create pizza templates. Cut yarn long enough to “slice” each pizza a few

times. Students will use the yarn to divide the pizza into even pieces based

on the order taken. Use worms, dinosaurs, bugs, etc. to create

toppings on a fraction of the pizza.

Everybody's doin' the Action Fraction!

Gettin' mathematical satisfaction!

Dancin' a radical new sensation!

Sweepin' it's way across the nation!

Reach up high as you can go.

Bend down low and touch your toes.

Lift your hands half way up,

And mark the middle with a clap, clap,

clap.

Reach up high as you can go.

Bend down low and touch your toes.

Lift your hands one fourth the way.

Snap your fingers, step and sway.

Reach up high as you can go.

Bend down low and touch your toes.

Lift your hands three fourths the way,

Jiggle and shake 'em any old way.

Turn one third and wave your hand.

Turn another third and wave once more.

Turn another third and you're right back

home

Ready to what you did before.

Everybody's doin' the Action Fraction!

Gettin' mathematical satisfaction!

Dancin' a radical new sensation!

Sweepin' it's way across the nation!
