Max Maths, Year 3, Learn together, Reviewing and naming fractions (2)

In a Year 3 mathematics lesson from Max Maths, students are reviewing and naming fractions, focusing on understanding and visualising parts of a whole. For instance, they look at a triangle divided into three equal sections, with two of these sections shaded. This visual representation helps students grasp that two-thirds of the triangle is coloured, which is written as 2/3. This fraction indicates that two out of the three equal parts are shaded. The lesson reinforces the concept that fractions represent parts of a whole, with the numerator (top number) showing how many parts are being considered, and the denominator (bottom number) indicating the total number of equal parts.

Similarly, the lesson explores fractions using a number line divided into ten equal parts. Here, students see that four parts of the number line are shaded, which is expressed as 4/10, or four-tenths. This fraction means that four out of the ten equal parts are coloured. The lesson continues by reinforcing the terminology associated with fractions: the numerator is the number above the fraction line, representing the parts of the whole that are being counted, and the denominator is the number below the line, representing the total number of equal parts that make up the whole. For example, in the fraction 2/3, which represents two-thirds of the triangle, '2' is the numerator and '3' is the denominator, indicating that two out of three equal parts of the triangle are shaded.
