“Which fraction is bigger?”
Your child sees the bigger denominator and chooses the smaller amount.
FOR PARENTS WHO KEEP HEARING “I DON’T GET IT”
When the math on the page
doesn’t make sense yet.
Your child might remember a rule, then get stuck when the question changes. You want to help—but another explanation of the same rule isn’t always enough.
Shop Class Math gives you something to make together, a question to ask, and an answer with the reasoning explained. Start by making the numbers visible.

Does this sound familiar?
“I knew this yesterday.”
A remembered procedure doesn’t carry over to a new problem.
“How do I explain it?”
You want to help without preparing a lesson or turning the evening into another worksheet session.
These are examples of learning difficulties—not a diagnosis. The starting point is finding out what your child understands.
TRY IT TOGETHER · FRACTIONS & MEASUREMENT
Make a fraction marker for a 12-inch strip.
Use paper or thin cardboard to make a reusable measuring strip. The goal is to connect a fraction of a whole with an actual length—not just memorize a rule.
Gather: paper or card, an inch ruler, a pencil and two colors. An adult cuts a strip 12 inches long and checks its length. Put scissors away before the lesson. No printer needed.
1. Ask before showing
“Which is farther along this strip: one-half of its length, or three-eighths? Show me your guess.”
Let your child point or draw. Don’t supply the answer yet.
2. Open the visual explanation together
Divide the whole strip into eight equal parts. Each part is 1½ inches long. Three parts reach 4½ inches; four parts reach 6 inches.
Illustration—not a full-size cutting template or a photograph.
Parent prompt: “How many eighths reach halfway? How can the strip help us compare?”
Reasoning: ½ = 4/8, so ½ is larger than 3/8. On this strip, the marks are 1½ inches apart. The comparison only works this way because both fractions refer to the same whole.
3. Make the idea physical
Mark every 1½ inches, starting at zero. Label the third mark ⅜ and the fourth ½. Ask your child to explain the marks in their own words. If needed, fold a paper strip in half first, then compare its crease with the marks. That is supported practice.
4. Check a different example
On another day, use an 8-inch strip. Ask: “Where is ⅜ of this strip? Where is ½? Which is farther from the start?” Keep the answer closed while your child tries.
Parent answer for the new strip
⅜ × 8 = 3 inches. ½ × 8 = 4 inches. One-half is farther from the start; the gap is 1 inch. The fraction relationship stays the same, but the lengths change with the whole.
Notice whether your child explains independently or needs help. One correct answer does not establish lasting understanding.
Too much for today? Start with halves in our free bookmark lesson. If counting is the better starting point, start with three objects. These links are alternatives, not prerequisites.
This is the system—not just a stack of worksheets.
Make it visible
Use objects, measurements and drawings to give the numbers a meaning.
Know what to ask
Follow parent prompts and worked answers. You don’t have to invent the explanation.

What we can—and can’t—promise
We provide a structured way to practice math together. We cannot promise a particular learning result or that a project will resolve every difficulty. These are supplemental pilot materials; physical builds and family outcomes remain unverified. This illustrated walkthrough is not a customer testimonial or a filmed family trial.
