This is a classic you can play anywhere. Try it on long car journeys.

The objective is to guess the mystery number.

You say: "I've thought of a number, added 3 to it, and the result is 7. What is my number?"

Make the questions as easy as possible to start with. As your child gains confidence, make the questions are little harder.

At some point, say you're going to call the mystery number 'x'. Then ask the question in equation form.

Now don't panic. It's simple.

Suppose your question is: "What number plus 3 makes 17?"

You call the mystery number 'x'. And so your equation is:

x + 3 = 17

You ask your child "if x plus three is seventeen, what's x?"

You can also reverse roles and ask them to give you some puzzles. Most kids enjoy this. And it trains them to think more creatively about algebra too.

*** Summary ***

Just a few subtle changes in the way your child thinks can have profound effects on their results in the math class.

Don't overload your child. Go in very small steps with lots of similar examples to give practice and confidence.

Even the smallest thing may be a stumbling block. Like understanding that 'x' means '1x' (the '1' is not usually written down).

Give lots of praise and reward to create and reinforce the 'feel good' factor.

As in any kind of teaching, it's better to ask lots of questions rather than keep telling someone something.

Take enough little leaps and at some point your kid will experience the "Aha!" moment when the whole algebra thing suddenly clicks into place.
