This video explains how to add and subtract whole hundreds using different strategies.

This video presents several strategies for completing simple additions up to 10.

This video presents a simple and effective strategy for completing calculations involving addition and subtraction of the number 9.

In this video, we explain the different steps involved in mental calculation and the importance of memorizing numerical facts.

In this video, we will learn how to compare large numbers. To do this, we must first count the number of digits in each number.

In this video, I teach students how to compare and order numbers up to 999.

In this video, I explain how to compare fractions. Students first learn what a fraction represents through a concrete situation.

The objective of this video for students is to convert measurements of duration, particularly in order to compare them.

In this video, I show how to perform a decimal division of two integers. The quotient will therefore have an integer part and a decimal part.

In this video, we review the technique of dividing a decimal number by an integer. For example: 35.43 : 12. Simply start by dividing the integer part, place a comma in the quotient, and then divide the decimal part.

In this video, we explore mental math techniques for determining doubles and halves of numbers up to 100. This is an essential math skill that children will learn to master in a fun and interactive way.

Through this video, children learn about fractions, particularly halves (or one-half) and quarters. I show how to cut a cake, a strip of paper, or even a disc so that each piece is equal.

In this video, students learn how to express measurements using fractions.
