In this post we are going to learn about the criteria of divisibility by 3, 4, 9 and 11. Criteria of divisibility by 3 A number is divisible by 3 when the sum of its digits is a multiple of 3. For example: Is 1098 divisible by 3? We add all the digits of 1098: 1 […]

In this post, we are going to explain reducible equations with several examples taken from Smartick’s daily sessions. We will begin with some easier examples, and work our way toward those that are more complicated. If you need to review what an equation is, and its terms, you can take a look at this previous […]

In today’s post we are going to answer the question, what is factorial decomposition? I hope that by the end of the post you’ll have it crystal clear. Definition of Factorial Decomposition We are going to start by remembering what a ”factor” is in mathematics. A factor is every number that is multiplied by another. […]

For this entry, we are going to learn some surprising facts about prime numbers. We would recommend reading our post about prime numbers and composite numbers first, to refresh your knowledge about these numbers. Are you ready to move on? Perfect! I’m sure that you know it is possible to write some numbers as products of […]

I am sure this sounds familiar to many of you: To calculate the least common multiple (LCM), we have to choose between the common and uncommon factors that have the highest exponent. But what does it mean? Why do we have to choose from all factors…and out of the common factors, why the ones with […]

In previous posts we’ve learned about prime numbers and composite numbers. Today we’re going to look at different sequenced prime numbers activities involving prime numbers that Smartick students work on. We’ve included examples of different types and levels, from identifying whether a number is prime or composite to finding the least common multiple and highest common factor through […]

In today’s post, we are going to learn about the different methods we can use to simplify fractions, as well as a trick that is essential to simplification. We will also see some examples of activities that children solve during their Smartick sessions. What is Simplifying Fractions? Simplifying a fraction is reducing the numerator and […]

In today’s post, we are going to explain exercises with subtracting fractions. We will also see some of the Smartick activities about subtracting fractions that children complete during their sessions. In an earlier blog post, we explained how to subtract fractions. You can take a look and review this post before reading more. In order […]

In this post, we are going to learn how to factor into prime numbers. First, let’s look at what factoring is: writing a number as the multiplication of other numbers. For example, let’s factor the number 12. 12 = 3 x 4 12 = 2 x 6 12 = 1 x 12 All 3 cases are […]

Are you ready to learn how the greatest common factor is calculated? We’ll explain it to you in this post along with examples and videos to help you better understand the GCF. It’s also called GCD (Greatest Common Divisor) and HCF (Highest Common Factor). Let’s go! What is the Greatest Common Factor (GCF)? In mathematics, the […]

In this post, we are going to learn a mental math strategy for multiplying by 11 using a simple method. Mental Math Strategy 1: Multiplying a 2-digit number by 11 It’s only a matter of adding the number’s two digits and then putting the result in between the two numbers. Let’s take a look at some […]
