If x is zero, is the following true?
7x  2 < 6x  2 < 3x + 4
In the back of your books write down at least 10 values of x which satisfy this inequality statement.
"<" means "is less than"

When x is zero the statement is not true.
Here are ten values of x which make the statement true:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
there are of course many other values which make the statement true.
An inequality like this can be solved by splitting it into two parts:
7x  2 < 6x  2 x < 0 
6x  2 < 3x + 4 3x < 6 x < 2 
So the complete answer is x < 0
Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

Graphic Display CalculatorThis handheld device and companion software are designed to generate opportunities for classroom exploration and to promote greater understanding of core concepts in the mathematics and science classroom. TINspire technology has been developed through sound classroom research which shows that "linked multiple representation are crucial in development of conceptual understanding and it is feasible only through use of a technology such as TINspire, which provides simultaneous, dynamically linked representations of graphs, equations, data, and verbal explanations, such that a change in one representation is immediately reflected in the others. For the young people in your life it is a great investment. Bought as a gift for a special occasion but useful for many years to come as the young person turns into an Alevel candidate then works their way through university. more... 
iPad AirThe analytics show that more and more people are accessing Transum Mathematics via an iPad as it is so portable and responsive. The iPad has so many other uses in addition to solving Transum's puzzles and challenges and it would make an excellent gift for anyone. You have to hold iPad Air to believe it. Itâ€™s just 7.5 millimeters thin and weighs just one pound. The stunning Retina display sits inside thinner bezels, so all you see is your content. And an incredible amount of power lies inside the sleek enclosure. So you can do so much more. With so much less. more... Before giving an iPad as a gift you could add a link to iPad Maths to the home screen.
