My Grade 7 Child Is Struggling With Negative Numbers: A Guide for Alberta Parents

Your child used to manage Maths homework on their own. Now a question such as −3 + 8 brings everything to a stop.

They may remember a rule about “two negatives making a positive,” but apply it to the wrong question. You explain it one evening, and the next day they are confused again.

For many learners, negative numbers are a change in how they think about numbers. Numbers can now describe temperatures below zero, a loss of money or a position on the other side of zero. If that meaning is unclear, memorised rules can quickly become mixed up.

If your child is in Grade 7 in Alberta, a short conversation can help reveal which part they need to understand.

Start with a number line

Draw a horizontal line and mark the numbers from −10 to 10, with zero in the middle.

Ask: “Which is greater: −2 or −7?”

The answer is −2 because it is farther to the right on the number line. A child who says −7 is greater may be looking only at the 7 and the 2, without considering what the negative sign means.

Try a temperature example:

“It is −7°C in the morning and −2°C in the afternoon. Did it get warmer or colder?”

It got warmer by 5°C. Connecting the numbers to a situation can help your child make sense of their positions.

Three questions to try together

These are practice examples, not an official Alberta assessment. Ask your child to show or explain each answer using the number line.

1. Adding a positive number

Question: −3 + 8 = ?

Answer: 5.

Start at −3 and move eight places to the right. You cross zero and finish at 5.

If your child answers −11, ask which direction adding a positive eight should take them.

2. Subtracting a positive number

Question: 4 − 7 = ?

Answer: −3.

Start at 4 and move seven places to the left. After four places you reach zero; three more places take you to −3.

Ask your child whether the answer should be greater or less than 4 before they calculate.

3. Subtracting a negative number

Question: 2 − (−3) = ?

Answer: 5.

This one often causes confusion. You can connect it to a change in temperature: moving from −3°C to 2°C is a rise of 5°C. Then return to the number sentence and discuss why subtracting −3 from 2 gives 5.

If your child can complete the first two questions but struggles with this one, that is a useful, specific point to work on. There is no need to repeat every integer question from the beginning.

Why rules alone can be confusing

A child may say, “Minus and minus make plus,” without knowing whether they are adding two negative numbers or subtracting a negative number. Those are different situations.

Compare:

• −2 + (−3) = −5
• 2 − (−3) = 5

Both questions contain two negative signs, but they do not have the same answer. A number line and a spoken explanation can help your child see what each operation is doing.

When they get an answer, ask: “Does it make sense for the result to be positive or negative?” This builds the habit of checking rather than relying entirely on a slogan.

What if negative numbers are affecting algebra too?

Your child might understand how to solve an equation but make an integer error in the middle. For example:

x + 5 = 2

To find xx, they need the number that becomes 2 after adding 5. The answer is −3, because −3 + 5 = 2.

If a child cannot comfortably reason through −3 + 5, practising many more equations may increase frustration. Strengthening the integer skill first gives them a better foundation for the algebra work.

How to help without a nightly argument

Choose a calm time and practise a few questions, rather than restarting the entire homework sheet after your child is already upset.

Use the same number line for several days. Let your child explain where they start, which direction they move and where they finish. When they become more confident, ask them to picture the movements before drawing them.

If they make a mistake, say, “Show me what you were thinking.” Their explanation will help you see whether they misunderstood the negative number, the operation or the wording of the question.

When should you consider extra Maths support?

Speak with your child’s teacher if errors with integers continue across assignments or your child is losing confidence in Maths. Ask which topics the class has covered and whether negative numbers are the main difficulty or one part of a wider gap.

A tutor should look at your child’s working, not only the final answer. One learner may need a clearer understanding of the number line. Another may understand simple integer questions but struggle when they appear inside equations or word problems.

A focused plan should help your child explain their method, practise it and then apply it independently to new questions.
