The current lesson is planned in detail in the Lesson Plan (above) and sets out to encourage children to use their previous knowledge to solve a problem to calculate how many circles in a new array (which they will find is 23 times 3). The plan is to find different methods for doing this, to consider which are complicated and which are easier and, if any child suggests column multiplication, to link this to the practical activities. The longer-term goal is to make the children aware of the advantages of column multiplication building from meaningful experience related to practical examples.
Key Points:
The array method offers a powerful visual approach to explain multiplication in terms of groups of items. The above example shows that 60 can be expressed as 20 groups of 3 items or 3 groups of 20 items, which also illustrates the commutative property of multiplication. In this problem, the challenge is for the students to show an array that represents 63.
The teacher starts at the left-hand side of the board with the problem, writes up the development of the lesson, circling important points in yellow, so that the whole lesson structure is seen on the board at the end of the lesson.
