In today’s post, we are going to review vertical subtraction. As always, we are going to review with examples that will help us to understand what vertical subtraction consists of and how to solve such problems. Before we begin, let’s review the material that we’ll use to subtract. We’ll use individual cubes to represent 1s. […]

In today’s post we are going to work with proportions. Today, we’ll start by looking at problems with proportional numbers. In order to solve problems with proportional numbers, the first step is to know the concepts of ratio and proportion. Ratio A ratio is the quotient of two numbers or quantities that are being compared […]

In today’s post, we’re going to talk about multiplying fractions using the Singapore Math Bar Model. Let’s take a look at an example: Amy drew a rectangle and colored in 2/5 of the parts purple and after, she striped 1/2 of them yellow. We can calculate the answer by observing the described section between the […]
