Visualizing Addition of Dissimilar Fractions Without and With Regrouping
Objective: Visualize addition of dissimilar fractions without and with regrouping.

Mother has one whole cake. First she sliced 1 and then 1 of the cake. What part of the cake did she slice? 2 4 Let’s solve the problem following the steps in problem solving.
1. What is asked for?
The part of the cake that was sliced.
2. What are the given data?
1 was the first sliced , and 1 was the second sliced 2 4 3. What is the mathematical sentence?
1 + 1 = n

2 4

...Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom, such as 9/8. I will explain how to convert these...
...Subtraction with Regrouping
Abstract
This literature review focuses on twodigit subtraction with regrouping. Many students struggle with this concept and place value is a major stumbling block for students trying to master subtraction. This paper will also show that delaying the introduction to the traditional algorithm and allowing students to use their invented strategies as well as paying attention to the concreterepresentationalabstract instructional...
...Lacsap’s Fractions
IB Math 20 Portfolio
By: Lorenzo Ravani
Lacsap’s Fractions Lacsap is backward for Pascal. If we use Pascal’s triangle we can identify patterns in Lacsap’s fractions. The goal of this portfolio is to ﬁnd an equation that describes the pattern presented in Lacsap’s fraction. This equation must determine the numerator and the denominator for every row possible.

Introduction to Psychology
Addiction as Choice?
Substance abuse is a pervasive problem throughout the United States. It affects all populations, socioeconomic groups, ages, and races. Within the community of substance abuse treatment providers, there is an ongoing debate on whether addiction is a disease, or whether individuals who abuse substances choose to engage in the behavior. There is evidence to support both positions. This paper will...

Imagine if your connection at home has been down for a few days. It would be a bit difficult to manage. Life without the Internet is an everyday scenario for most of the world. To me, life without the Internet is fine and of course, livable, but not much informative. Information are everywhere around us. The developed whole world is addicted to info. The Internet...
