Your teenager brings home a Math 20-1 test. The mark is much lower than you expected. You ask what happened, and they say, “I studied. The questions were just different from the homework.”
That answer may be true. It also gives you a place to start.
If your family lives in Calgary, Edmonton or elsewhere in Alberta, you do not need to become your child’s Maths teacher overnight. You need to find out what went wrong on the test so the next few weeks of practice address the right problem.
What is Math 20-1?
Math 20-1 sits in Alberta’s Math 10C → Math 20-1 → Math 30-1 sequence. Students work with topics such as quadratic functions, trigonometry, radical and rational expressions, sequences and inequalities. The course asks them to use earlier algebra skills in increasingly complex questions.
A disappointing mark does not tell you whether your child has misunderstood the current topic, forgotten an earlier skill or struggled to apply what they know. Their marked answers can help you tell the difference.
Look at the first mistake, not just the final mark
Choose three questions your child lost marks on. For each one, ask:
- Did you understand what the question was asking?
- What did you decide to do first, and why?
- Which line were you last confident about?
- Could you try a similar question without looking at the correction?
Suppose your child loses marks on a quadratic question. They may understand that they need to find where a graph crosses the horizontal axis but make an error while factoring. That points to an algebra skill they can practise. If they factor correctly but cannot explain what the answers mean on the graph, they need help connecting the equation and graph.
Those two students need different lessons, even though both got the same question wrong.
Four patterns a parent may notice
“They know the method until the question looks different”
Your child may have memorised the order of steps in a worked example. Ask them to explain why they chose that method. Then give them a fresh question with slightly different wording. If they cannot begin, they need practice recognising the mathematical idea in a new setting.
“They understand the lesson but keep making algebra errors”
Find the earliest incorrect line in their working. Repeated errors in factoring, signs or rearranging equations can affect several Math 20-1 topics. A short review of that underlying skill may help more than repeating the entire new lesson.
“They finish questions but never check their answers”
Have your child put an answer back into the original equation when appropriate. Ask whether it makes sense in the question or on the graph. This is particularly helpful when a question involves an expression with restrictions.
“They leave questions blank”
Ask your teenager what they could identify from the question, even if they could not finish it. Could they name the topic, write a relevant equation or draw a quick sketch? Building a reliable first step can help them attempt more of the paper.
What should we ask the teacher?
Send a short, specific message. For example:
“We reviewed my child’s recent Math 20-1 test and noticed difficulty with quadratic graphs and factoring. Which skill should they focus on first, and are you seeing the same issue in class?”
Ask which topic the class will cover next, too. That helps you arrange support that addresses the learning gap while keeping your child connected to current lessons.
How should my child practise before the next test?
Avoid making every study session a full practice test. Start with the recurring error you found.
If factoring is the problem, practise a few examples and then use factoring in a Math 20-1 question. If interpreting a graph is the problem, ask your child to explain what an intercept or turning point tells them in the question they are working on. Finish with one new question completed independently.
When they get it wrong, ask for their reasoning before showing the solution. You want to know whether the same gap is still there.
When might a tutor help?
Consider a tutor if your child makes the same mistake after reviewing corrections, cannot start homework alone or is becoming anxious about every Maths test. Take the marked test to the first session. It gives the tutor evidence to work from.
Ask the tutor to tell you:
- Which skill is affecting your child’s Math 20-1 work
- How they will address it alongside the current school topic
- What your child will be able to do independently after a few lessons
- How they will check whether the improvement lasts
The aim is for your teenager to understand why a method works and recognise when to use it.

One low test mark can become useful information if you identify the first mistake and act on it. Start with your child’s marked work, speak with their teacher and focus practice on the skill that keeps causing difficulty.
