In today’s post we’re going to take a look at the compound rule of 3, but first we need to remind ourselves about the simple rule of 3. I’ve selected some previous posts that you can look at if you need to: Rule of three: Direct and Inverse Direct and Inverse Rule of three Problems […]

In today’s post, we’re going to take a look at some strategies for solving problems that involve incomplete horizontal additions and subtractions, using examples to help us. Acquiring mental calculation strategies is not always easy, since there’s no defined “best method” for everyone, and it can be frustrating if you don’t pick it up quickly. […]

In today’s post, we’re going to see how to solve some of the problems that we’ve introduced in Smartick: fraction word problems. They appear during the word problems section at the end of the daily session. We’re going to look at how to solve problems involving addition and subtraction of fractions, including mixed fractions (the […]

In this entry, we’re going to explain how to break down or factor a number to its prime numbers step by step. Before we start anything, feel free to look at these entries where we explain what “factoring” means and what a prime number is so you can refresh your memory. Factorization How to factor […]

In today’s entry, we are going to look at the distributive property of multiplication with respect to addition and subtraction. The distributive property is one of the properties of multiplication that is applied with respect to addition or subtraction. This property tells us that if we add or subtract several numbers and we multiply the […]

Addition and multiplication both use the associative property, while subtraction and division do not. We’re going to to get up close with each situation to get a better idea. The associative property in Addition ♥ Addition indeed has the associative property. Whatever numbers a, b, and c may be, they always end up the same: […]

In today’s post, we are going to solve a probability problem that appeared in Madrid’s 2008 Standardized Elementary Testing Exam (CDI): Let’s start by reviewing some probability concepts. Sample space: The sample space refers to all of the possible outcomes of a random experiment and it’s often represented by E (or as omega, Ω, from […]

In today’s post we’re going to look at the concept of equations. To start, we’re going to take a look at this situation: “One third of Cecilia’s flowerpots contain daisies, half of them are full of pansies, and the other twelve contain poppies. How many flowerpots does Cecilia have?” Think about it, and see if […]

What is a series? And a pattern? In this post, we’ll teach you all about series and patterns. To talk about patterns is to talk about regularities. Regularities are everywhere and it’s a special skill to be able to recognize them. Regularities exist in natural and social phenomena; the search for regularities is the base of […]

Set theory is known as a math content area but its uses go far beyond the development of logical-mathematical thinking. Understanding set theory allows us to use the sets as a tool to analyze, classify, and organize the knowledge acquired to develop the complex conceptual network in which we store our learning. So there are […]

What needs to be done in order to solve multiplication problems? Isn’t it enough to just multiply the numbers that we’re given? No! Because… What’s more important is UNDERSTANDING the multiplication problems. This is why we’re bringing you some multiplication problems today where YOU WON’T NEED TO USE MULTIPLICATION, but rather, TO THINK CRITICALLY. Ready? […]

Welcome to Smartick’s blog! In today’s post we are going to learn some geometry and talk about prisms: what they are, what are their principal elements, the types of prisms that exist and how we can calculate their areas and volumes. What Are Prisms? A prism is a polyhedron that has two equal, parallel sides […]
