Pizza Fractions Project! - 4th Grade Frolics I wanted to share a fun project my kiddos did. We had been working on fractions and I wanted to come up with a little fun that would reinforce some of what they learned as well as let them have some fun being creative. WARNING.....LOTS of pictures ahead....they all were so unique and creative, I had to share them all:)Directions Google Doc HERE We were fortunate enough to have a local pizza place donate enough boxes so each of my kids could have one. This is the first time I have done this project.....I'm sure next time I will add to it but for a first time, I am pleased with it and THRILLED with how they turned out.

Math in Daily Life When you buy a car, follow a recipe, or decorate your home, you're using math principles. People have been using these same principles for thousands of years, across countries and continents. Whether you're sailing a boat off the coast of Japan or building a house in Peru, you're using math to get things done. How can math be so universal? First, human beings didn't invent math concepts; we discovered them. Also, the language of math is numbers, not English or German or Russian.

Number Frames Overview Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing. As students advance, custom frames can be constructed to help visualize factors, products, fractional parts and more. Using LEGO to Build Math Concepts I was not one of those LEGO® kids growing up. Sure, my brothers had LEGO bricks, and every so often I’d kidnap some tiny LEGO men for a make-believe game. But I didn’t truly appreciate the engineering capacity of those studded plastic bricks. They were just so rigidly rectangular! As an adult, I’ve come to appreciate LEGO, both for its rectilinear aesthetic, and even more so, for its mathematical might.

DIY Math Multiplying Manipulatives * Evil Math Wizard I teach math to 2-5th graders, which is a big range. But it’s fun for me to see the development changes especially when using objects to help them figure things out, from fingers, blocks, counters, fractions kits, etc. I encourage my students to use them. I don’t want them to hide their fingers under their desk when they are figuring things out. It’s an important part of math to visualize. And because I have these kids up to 5th grade, they use their fingers less and less, naturally.
