how can you start Introduction of teaching mathematics in foundation phase about function with input of (1,2,3) and rule of x³ with output of ( 1,8, 27)
To introduce the concept of functions in the foundation phase, we can start by explaining that a function is like a machine that takes in a number (input) and gives out another number (output). In this case, we will use the example of the function with the rule x³, where the input numbers are 1, 2, and 3, and the corresponding outputs are 1, 8, and 27 respectively.
We can illustrate this concept using a simple chart or table:
Input (x) | Rule (x³) | Output
1 | 1 | 1
2 | 2³=8 | 8
3 | 3³=27 | 27
By looking at this table, students can see how the input numbers are being transformed by the rule x³ to produce the corresponding output numbers. This helps them understand the relationship between the input and output of a function. We can then encourage students to find other examples of functions and explore how different rules can change the output based on the input.
