How Parents Can Support Two Kids at Different Math Levels
Mathnasium's education specialists explain how to help two kids at different math levels grow with confidence, not comparison.
Crystal Lake students returned to the classroom in late August, and after the first month of school, a clearer picture may already be forming of where your child stands in each subject, including math.
If math has not gotten off to the start your child hoped for, there is still time to respond early in the semester, before small misunderstandings or missed work become harder to manage.
Today, we’ll share common ways math difficulties can begin to show up during the first month of school, along with practical steps parents can take to help their child regain momentum and get back on track.
Math struggles after the first month of school tend to follow familiar patterns, and Mathnasium of Crystal Lake sees them show up in local students year after year. Here are five common ones, along with why each tends to happen.
Some students feel slower with calculations or less confident using skills that felt familiar last spring, even weeks after summer ends. Researchers call this pattern summer learning loss, often known as a summer slide, a slowing of academic progress that happens over school breaks.
Research has found that math is particularly affected: a review of 39 studies found that summer decline was greater in math than in reading, with the steepest drops in math computation and spelling. On average, students lost about a month of grade-level learning over the break.
At home, you can recognize it as:
Your child needs to count on fingers for a multiplication fact like 6 × 7 that they had memorized cold back in May.
Homework that used to take 15 minutes now stretches to 30, even though the assignment covers the same kind of problems as before break.
Your child asks "wait, how do I start this?" on a problem type they solved independently just a few months ago.
Simple mental math, like making change or splitting a bill, takes noticeably longer or gets set aside for a calculator when it didn't before.
Your child re-reads the same homework instructions two or three times before starting, on material that used to be a quick glance.
Crystal Lake students move through District 47's math curriculum before advancing into District 155's high school courses, and several transition points ask them to use math in new ways.
Fractions, usually in upper elementary, test whole-number habits. Students often need to understand that fraction operations follow different rules and represent quantities differently than whole numbers do.
Ratios, proportions, and negative numbers, often in middle school, ask students to reason abstractly, making sense of relationships between quantities or numbers below zero for the first time.
Algebra I, commonly taken in middle school or early high school, asks students to translate words into equations and solve multi-step problems without a memorized example to follow.
Geometry, often in high school, shifts the goal from calculating to explaining, asking students to prove why a relationship is true rather than just find an answer.
Advanced high school courses ask students to connect several skills within the same problem, like algebra, functions, graphs, and trigonometry, which can feel like a lot at once.
This challenge can surface at any grade level, and it often becomes clearer once students are expected to complete more homework and prepare for tests on their own.
You may notice it in your learner in a few ways:
Needing class notes, textbook examples, or your help for nearly every problem.
Getting stuck as soon as a question appears in an unfamiliar format.
Struggling to explain why a method works or how they chose it.
New study habits take shape during the first month of school, but old habits often carry over from the previous grade too. One common pattern shows up the night before a quiz or test, when a student waits until then to review a full unit of math.
Cramming can make a student feel temporarily familiar with notes or worked examples, but it rarely builds the understanding needed to solve problems independently. Lasting math learning depends on remembering procedures, recognizing which strategy a problem calls for, and connecting new ideas to earlier skills.

By the first month of school, many students have already gotten feedback from a classroom math quiz, test, or graded assignment.
Crystal Lake students also encounter this through the school year's regular testing cycle, including District 47's periodic MAP assessments and coursework grading at the high school level.
A lower-than-expected result can be discouraging, especially when a young learner sees it as proof that they're "bad at math" rather than as feedback about a skill, a study method, or an adjustment to a new course.
You may hear things like, "I'm just bad at math," "I studied, so I should have gotten it. There's no point trying again," or "Everyone else understands this except me." Some students may also stop raising their hand or avoid harder problems because they're afraid of getting them wrong.

The first test can also give you a useful starting point. Look at which problems caused trouble and whether the pattern points to a specific skill that needs more attention.
If you've noticed any of these early math difficulties, the steps below can help your child figure out what needs attention, build stronger skills, and feel more confident this semester.
A look at a quiz and homework assignments can tell you exactly where to focus first.
Look for the clues: Pull out one recent math quiz or test and homework assignments on the same topic.
Spot the patterns: Search for the same kind of error showing up more than once, like fraction calculations, negative-number mistakes, skipped equation steps, or trouble turning a word problem into an equation.
Let them try it without help: Ask your child to solve one missed problem out loud, without notes, and notice the first step where they pause or hesitate.
Compare that step to their homework: If the same issue shows up in both places, that's a strong clue about what to review. If homework is only correct with notes or examples open, your child may just need more practice working on their own.
Choose what to work on next: Use what you found to choose a single focus, like reviewing the skill, practicing a few similar problems over the next few days, or asking the classroom teacher a specific question.

If the first review shows a missing earlier skill is blocking the current work, the fastest fix is refreshing that skill first.
Find the real starting point: Look at the current problem that caused trouble, then work backward to figure out which earlier skill it depends on.
Check the earlier skill: Try one or two simple problems on that skill alone to see if it's solid.
Refresh before moving forward: If it's shaky, spend a few short sessions over several days rebuilding it before going back to the current assignment.
Match the fix to the difficulty: If equations with fractions are the problem, check fraction operations and common denominators first. If graphing feels confusing, check whether your child is comfortable evaluating expressions and working with positive and negative numbers.
Rebuilding the skill underneath the struggle usually makes the current classwork feel far more manageable than practicing a problem your child isn't ready for yet.

Spacing out math practice beats cramming, and the research backs this up clearly. In a classroom study of 11- and 12-year-olds, students who spread the same number of practice problems across three sessions, one week apart, scored higher on a test a month later than students who did all the practice in one sitting.
Here's how to build that into your week:
Set short, regular check-ins: Aim for two or three brief math sessions each week instead of one long review the night before a quiz or test.
Warm up, then move forward: Start each check-in with one or two problems from an earlier lesson, then add a few from the current topic.
Let your child try first: Have them solve problems before checking notes or examples. Notes can help correct a mistake afterward, but the first attempt should show what they can recall on their own.
Keep a "come back to this" list: Save problems that were missed or needed help, then revisit similar (not identical) versions a few days later.
Plan around known test dates: When a quiz or test is announced, spread the review across the remaining days instead of saving it all for the night before.
When homework gets frustrating, giving your child the answer can feel like the quickest way to help. But asking a question or offering a small hint can do more to support their learning. It gives them a chance to work through the problem themselves and think independently.
Research on parental homework-helping behavior found that productive struggle, or working through something just beyond a student's current understanding, supports learning math concepts and procedures, but only when parents lean toward guiding and not taking over the task.
Let your child learn the problem, figure out what it's asking, and try a first step before you explain anything. If they stall, ask questions that hand the work back to them, like "What do you know already?" or "What could you try first?"
When they reach an answer, have them talk you through it. That reveals whether they understand the method or are just repeating a step without knowing why.
If they're still stuck, offer a smaller nudge instead of the full answer, like pointing them back to a formula or an earlier example, and let them decide how to use it.
Still, watch for the point where struggle stops being productive: if they keep repeating what isn't working, pause and find the missing skill instead of pushing them to keep guessing.

How your child talks about a bad grade matters almost as much as the grade itself. Research on students’ beliefs about their ability to improve suggests that the way they interpret a setback can shape what they do next.
A longitudinal study of 373 seventh graders found that kids who believe they can get better at math with effort tend to keep improving, while kids who believe their ability is fixed tend to stall out, and the way parents respond after a low score can nudge a child toward either belief.
Ways to rebuild confidence after an early low score:
Focus on what happened, not who your child is: Say "These problems needed a skill you're still building," instead of "You're bad at math."
Name the next learnable step: Tie the mistake to one specific action, like reviewing negative numbers, practicing fraction operations, or learning how to set up word problems.
Use "yet" with a plan: "You don't feel confident with this yet. Let's work on two problems today and come back to this later in the week."
Make improvement visible: Save one missed problem, then revisit a similar one after some practice. Your child will trust their progress more when they can see a skill improve.
Praise strategy and persistence: Notice when your child shows their work, checks an answer, tries a new strategy, or returns to a hard problem. Skip general labels like "You're so smart" or "You're just good at math."
Keep goals small and near-term: Something like "solve three fraction problems without notes" gives your child a concrete win to work toward before the next test.
