    Make sure to check the symbol, to see if you are allowed to use a calculator for each question.

  • Trial and improvement methods

    When we say ‘trial and improvement’ we mean having a logical attempt at something, then using the result to figure out where to try next.

    Imagine if you’re trying to guess a number with a friend.

    You guess 6, your friend says higher. You guess 20, your friend says lower.

    You now know you need to pick a number between 6 and 20, you’re best to pick a number right in the middle, this reduces the number of options left as fast as possible, on average.

    You say 13, your friend says higher. This makes the number of choices left smaller each time, and is generally the most efficient way to

    find a solution.

    In the questions below, you are going to pick a number to try as x. Substitute it in, as you have practiced doing, and see if you get the desired answer. If not, fill in the table and then try again!

    You can use a calculator.

  • Forming expressions and equations

    Remember: an equation has an equals sign, an expression does not.

    Watch the video, then treat these questions as if the inequality sign were an equals. Notice on question 3 you need to draw your solution on a numberline also.
