5. Example Arrange consecutive numbers 1 to 5 in the given arrangement so that the vertical sum is equal to the horizontal sum.
6. 3 2 2 1 5 2 3 5 1 5 4 1 4 4 3 Total = 10 Total = 8 Total = 9
7. Example Arrange consecutive numbers 2 to 6 in the given arrangement so that the vertical sum is equal to the horizontal sum.
8. 5 3 3 2 6 3 6 5 2 4 6 2 4 4 5 Total = 12 Total = 11 Total = 13
13. Example Students get to practise addition of three numbers while developing higher-order thinking such as looking for patterns and relations, as well as their number sense.

21. Example How about the learning of multiplication facts or the multiplication table? Can it involve the development of higher-order thinking?

26. Example Students have a chance to develop the ability to make connections and also to develop visualization ability which is fundamental in the learning of mathematics.

32. Conclusion Drill-and-practice is mot mutually exclusive from higher-order thinking. This lecture gives examples of how drills can be used to develop a range of higher-order thinking.
