Working with One Variable 5 + a = 19 In this example ‘a’ is the variable. This can be represented using the bar model: 19 5 We can see that a a = 19 - 5 a = 14
Working with Two Variables 3 n + m = 17 In this example ‘n’ and ‘m’ are the variables. This can be represented using the bar model: 17 n n n m Now we need to look at the possibilities for ‘n’ and ‘m’.
3 n + m = 17 17 What would this look like if: n n n m 1 14 3 m would need to be: n=1 1 1 n=2 2 11 11 n=3 3 8 8 n=4 4 5 5 n=5 5 2 2 5 5
What about 23 = 2 s – t? We can still represent this using the bar model: 2 s 23 t We can see that 2 s (2 x s) must be greater than 23, therefore s must be greater than or equal to 12. We can write this as: s ≥ 12
23 = 2 s – t 2 s 23 If s = 12 s = 13 s = 14 23 = 24 - t 23 = 26 - t 23 = 28 - t t so t = 1 t=3 t=5 and so on!
Problem Solving and Reasoning Find a whole number that solves the equation 10 – x = 4 x Find a whole number that solves the equation 25 ÷ x = x Challenge: Can you find your own that works and explain how you found it? To help you do this, you can draw diagrams or use practical equipment.
