Explain why use of concrete material and hands on experiences, in teaching learning of mathematics at primary level are more effective. Illustrate with the help of one example each.
The use of concrete materials and hands-on experiences in teaching primary school mathematics significantly enhances understanding and retention among young learners. Concrete materials help bridge the gap between abstract concepts and practical understanding, making the learning process more engaging and relatable.

Much of Mathematics teaching is actually about encouraging children to become more aware about patterns they find and to use them in their thinking. Illustrate this in the case of the situation given below by answering the questions given in questions (i), (ii) and (iii), below.
“A mathematics teacher in class 5 showed the following pattern in the class.
46 X 44 = 2024
63 X 67 = 4221
71 X 79 = 4909
She gave some time for the students to identify the pattern. After some time she asked the students to find the answer of "84 x 86" in one second. One student answered 7224. Based on this situation, answer the following question.
i) What is the pattern used by the student?
ii) Explain why it works?
iii) Describe how it helps to encourage mathematical thinking.
