Best practices for teaching math in primary schools include using manipulatives to engage students physically, integrating real-world applications to relate concepts to everyday life, and promoting a growth mindset to encourage perseverance. Differentiated instruction allows for tailored approaches based on individual student needs and learning styles. Incorporating technology such as interactive apps and games can enhance engagement and foster a deeper understanding of mathematical concepts. Regular assessments help monitor progress and identify areas needing additional support. Collaboration and communication among teachers also enhance instructional practices.
