Real-world fractions and testing 3D glasses

In Math, we were doing fractions, and we we're getting a pizza party from Pizza Pizza. We're getting 6 pizzas because 23 people wanted pizza, but some people wanted more than just one piece. - Logan

Today we watched a movie in 3D, and it was called Shark Boy and Lava Girl. We made 3D glasses, and we watched the movie with them. - Kyra

After lunch, for afternoon, we were watching Shark Boy and Lava Girl in 3D, to try out our 3D glasses that we made. My glasses worked really good. - Hailey M.

After morning recess, Mr. H. told us that we're getting pizza. We've been working with fractions, and dividing them equally, and deciding what type of pizza to get, and adding them up in decimals and putting the number of slices all together in fraction version. - Jenna

Wanting to have the students see the application of fractions in the real world, we are having a pizza party. The students, having been doing lots of work with adding and subtracting fractions lately, as well as converting fractions to decimals, had to put their learning to use. After a lot of discussion, the students realized they needed to each figure out what fraction of a pizza they would eat, and then add those totals together in their table groups. Next, as a class, they had to add together the totals of all of the groups, in order to get a classroom total. They also successfully converted the fractions in their number sentence into decimals. They have now figured out that I need to order 6 pizzas. Tomorrow's jobs include figuring out how many pizzas we need to order of each of the flavour choices, and to come up with a total cost of all of the pizzas (they're really going to have to put their knowledge of adding decimals to use for that!).

In the afternoon, I surprised the class by informing them that I had bought a 3D movie for the class to watch, in order to test out their 3D glasses they had made in Science over the past few weeks. The movie was 'The Adventures of Shark Boy and Lava Girl in 3D', which we watched in the Music room, where we could block out almost all the light (a big thank-you to Ms. Evans for letting us use the space!). I'm pleased to report that everyone's glasses worked, and I definitely heard some ooooo's and ahhhhhh's during some of the 3D special effects. Bill Nye said it best: "Science Rules!"

You need fractions in the real world - who knew?!

Pepperoni and cheese were the most popular choices.

Some of the calculating the class was doing. The 40-23 equation was after a student suggested 4 pizzas would be enough for everyone... until they saw how little pizza that really would leave for everyone.

Immersed in the world of a 3D movie!
