Calcul mental

In this video, we discuss new sequences: by 2s, by 5s, and by 10s. Using a number line, students can discover that a sequence of numbers is an ordered series that regularly adds the same number.

In this video, we explore the 10 times table. To begin, we started by counting together in increments of 10 up to 100, showing that each new number is simply the previous one increased by 10.

This video focuses on learning the 2 and 4 times tables, an essential step in developing basic math skills.

This video is dedicated to learning the 3 times table.

In this video, I guide you through the 5 times table, which, when learned by heart, will speed up and simplify your math calculations.

In this video, we explain Pythagores' table. This is a double-entry table containing the results of operations, which can be multiplications or additions.

In this video, we explore the number 1000 and its different representations.

In this video, students learn to distinguish between quadrilaterals and learn about the characteristics of specific parallelograms.

In this video, we explore the geometric figure of the right-angled triangle.

In this video, we discuss angles. An angle is the part of a plane bounded by two rays originating from the same point.

In this video, students will learn how to recognize right angles and draw them.

In this video, we will explore techniques for effectively solving math problems.

In this video, we explore numbers up to 9,999. We explore how to break down and read large numbers.

To help students better understand time, this video teaches them the different months of the year.

In this video, we explain the concept of halves based on what students already know: doubles.
