P7M Algebra Facts & Games

Please use the weblinks below to practise what we have been learning in class. Remember the key rules when solving algebraic equations:

  • You want to get the variable (the letter) on its own on one side of the equation. For example, y + 5 = 10. What do you need to do to get the y on its own? Subtract 5! y + 5 – 5
  • Remember that whatever you do to one side of the equation, you must do to the other… so it balances! y + 5 – 5 = 10 – 5
  • Show all of your working, to record your thought process and understanding.              y + 5 = 10
  •                                          y + 5 – 5 = 10 – 5
  •                                                        y = 5
  • For more complex or multi-step algebraic equations, take one step at a time and use the above rules. For example,
  •                                      3y – 6 = 24
  •                              3y – 6 + 6 = 24 + 6
  •                                             3y =   30
  •                                      3y ÷ 3 = 30 ÷ 3
  •                                                 y = 10
