Primary School Math is one of the first few steps that determine how well students pick up core concepts, before they can move on to more advanced concepts.
One of the main reasons why children find it difficult to follow mathematics is because they are unable to link concepts that are abstract with real objects.
Visualization is important to understand mathematical concepts, instead of just learning by rote.
For example, measuring a real equilateral triangle piece and measuring its sides and showing them to be equal is easier for students to understand than just teaching them that all the sides of an equilateral triangle are equal. Some students struggle with mathematical calculations even though they have a good understanding of concepts.
They make mistakes as a result of misreading signs or numbers, or carrying wrong numbers and so on.
Primary mathematics curriculum has a collective effect, meaning, students should have a sound understanding of it before they can move onto other areas.
