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 44 = 2024
63 67 = 4221
71 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 × 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
A class 4 teacher wants to help her students understand the 3 categories of division of numbers. Construct one word problem of each category corresponding to the division 32 ÷8 = .4 Which of these categories of word problems is usually considered difficult for a primary school child to understand? Give reasons for your answer
Explain two implications for teaching mathematics of the fact that mathematical knowledge is hierarchically constructed. Give examples in support of your answers in the context of teaching negative numbers.
When a class 4 child was asked to mark the angle AOB in the following figure, she did the following
What could be the possible reasons for giving such answers? Suggest a class room activity that helps children explore and learn the concept of angle and also helps children to articulate reasons and construct arguments discussed in Sec. 18.3 of Block5
A class 5 child believe that the division always makes a number smaller. Describe an activity that could help her correct her misconceptions. Also describe an activity to assess how far the activity is effective.
How would you convince a child that any number multiplied by 0 is 0, using a teaching aid
Illustrate the use of each of the following in learning the concept of “fraction”.
i) an outdoor activity
ii) newspapers and magazines
