The Test My Kid Blog
Practical, growth-minded guidance on math, reading, grade-level expectations, and the test scores schools use, written for parents who want to know where their child really stands.
Kids learn even and odd fastest when they can see it: pair the objects up and either everything has a partner or one is left stranded. Here is how to build it from real pairs, connect it to the last digit, and spot the gap before it spreads.
Comparing fractions is where the bigger-number-means-more rule finally betrays kids. Here are the four methods that actually work, from the one-half benchmark to a common denominator, in the order to teach them.
You cannot add fractions until the bottoms match. Here is the step-by-step way to make them match, two worked examples, and the one check that catches most mistakes.
A ruler looks simple until your child has to name the tiny lines between the numbers. Those marks are a hierarchy, and reading the inch side is really a fractions skill in disguise. Here is why kids stall, the length-tells-the-fraction trick that fixes it, and a step-by-step routine you can run with the ruler in your junk drawer.
Multiplying fractions is the rare fraction rule that is actually simple to do and easy to get wrong for the wrong reasons. Here is the routine that makes it click, and why the answer gets smaller.
Why does scaling a recipe from 2 cups to 6 confuse so many kids? Because they add 4 to everything instead of tripling it. Ratios are the first place where multiplicative thinking has to take over from adding, and most stumbles trace straight back to that one switch. Here is how to teach ratios and proportions so the reasoning holds, the two traps that catch almost everyone, and how to tell a careless slip from a real gap.
Why is negative 5 smaller than negative 2? Why does subtracting a negative make the answer bigger? Kids get lost because negatives arrive as a pile of sign rules with no picture underneath. Here is how to teach integers from the number line out, the two moves that trip almost everyone up, and how to tell a sign slip from a real gap.
The jump into pre-algebra trips up kids who were fine at arithmetic, and it is almost always the same three things: the equals sign suddenly means balance instead of 'the answer goes here,' a letter is just a number you do not know yet, and you solve by undoing operations while keeping both sides even. Here is how to teach each one at home, and how to tell a concept gap from a shaky-facts gap underneath.
Mental math is not doing paper math in your head, it is a small set of strategies that make the numbers friendly first: make a ten, break a number apart by place value, and round then adjust. Here is how to teach those moves, why racing for speed backfires, and how to tell the difference between a strategy gap and a shaky-facts gap underneath.
Money looks like it should be easy, then a child learns that a dime is smaller than a nickel but worth twice as much and the whole thing wobbles. Here is how to teach the four coin values, connect them to skip counting your child already knows, count mixed coins from largest to smallest, and make change by counting up, all without a worksheet fight.
Most kids meet percentages as a pile of disconnected tricks: move the decimal, cross-multiply, is-over-of. It works until the numbers get weird, and then it collapses. Here is how to anchor everything to one idea, 'percent means per hundred,' teach the benchmark percents your child can do in their head, and tell whether a mix-up is a percent gap or shaky fractions underneath.
Order of operations looks like a list of six ranked steps, and that is exactly why kids get it wrong. Multiply and divide are one step, add and subtract are one step, and PEMDAS hides that. Here is how to teach it as four tiers with 'left to right' inside the last two, why the mnemonic backfires, and how to tell whether a mix-up is a rule slip or shaky multiplication underneath.
Area and perimeter get swapped constantly, and it is almost never because a child is careless. It is because both problems show the same rectangle and ask for two very different things. Here is how to teach perimeter as walking the fence and area as covering the floor, why the units are the whole game, and how to tell whether a mix-up is a formula slip or a missing picture.
Rounding looks like a tiny skill, but it is really place value in disguise, and the rules kids memorize fall apart the moment the numbers get bigger. Here is how to teach it from the number line, why the midpoint rule confuses so many kids, and how to tell whether a rounding miss is a rounding gap or a place-value one.
Telling time trips kids up because the same twelve numbers mean one thing for the hour hand and something completely different for the minute hand. Here is what is really going on, and a hands-on routine that builds it one layer at a time.
Decimals trip kids up because 0.45 looks bigger than 0.5 when you read the digits like whole numbers. Here is what is really going on, and a hands-on routine that rebuilds the idea from money up.
Most addition trouble is not about addition at all. It is carrying: the moment two digits add to more than nine and your child has to bundle a new ten. Here is how to make regrouping make sense, catch the classic mistakes, and know when the gap is bigger than one worksheet.
Most subtraction trouble is not about subtraction at all. It is borrowing: the moment the top digit is too small and your child has to trade a ten. Here is how to make regrouping make sense, catch the classic mistakes, and know when the gap is bigger than one worksheet.
Place value is the quiet foundation under carrying, borrowing, multi-digit math, and decimals, and when it is shaky everything above it wobbles. Here is how to build it from real groups of ten, connect it to the numbers your child reads every day, and spot the gap before it spreads.
Most kids get stuck on division because they are handed the long-division steps before they understand what dividing means. Here is how to build division from equal sharing, connect it to the times tables your child already knows, and make long division survivable.
Most kids stall on multiplication because they are told to memorize a grid before they understand what it means. Here is how to build the times tables from a few anchor facts your child can actually reason from.
Fractions trip up kids because they quietly break every rule whole numbers taught them. Here is what is actually going on, and a hands-on routine that rebuilds the idea from the ground up.
Math anxiety is a fear response, not a verdict on ability. Here's how to spot it, how to keep it from spreading at the kitchen table, and the small routines that help a frozen kid thaw.
Fact fluency is the bridge between counting on fingers and solving real problems. Here are the home routines that build it, the research behind them, and why speed alone isn't the goal.
Most kids who stall on word problems can already do the arithmetic. The gap is reading the story and deciding what to do. Here is a simple, repeatable routine that fixes it.
When a teacher says your child is behind in math, the fix is precision, not volume. Here is how to find the one or two skills they actually missed and close the gap with ten focused minutes at a time.
'I hate math' is almost never about math. It is about fear of being stuck or judged. Here is how to defuse the dread, find the specific skill underneath it, and rebuild your child's confidence.
