Did you know that counting spaces on a graph is different from reading what those spaces represent? For Bukit Timah families, ask your child to identify the axis label, unit and value of one interval before reading a point. This quick check can reveal why an otherwise sensible calculation begins with the wrong number.
Use a simple example: on a uniform axis labelled 0, 10 and 20, with five equal intervals from 0 to 10, each interval represents 2. A point three intervals above 10 represents 16. Let the child explain the interval calculation before supplying the answer.
Bring the actual graph to the tutor and separate three questions: can the child read the scale, locate the value and interpret what that value means? Start with the missing step. Use graph types appropriate to the student’s current programme rather than assuming every Primary or secondary class studies the same representation.

Choose the part closest to your child’s work and try one manageable learning check.
SECTION 1 OF 5
Read the labels before the shape
Ask what each axis represents and which units are used. In a temperature-time graph, a point gives a temperature at a particular time. Reading a height without identifying the variable can produce a number that does not answer the question.
Some displays use categories, keys or picture symbols instead of two numerical axes. Check the particular representation first. The tutor should identify whether the difficulty is reading a scale, interpreting a key or understanding the task.
SECTION 2 OF 5
Count intervals rather than marks
Between labelled values of 10 and 20, five equal intervals mean each interval is 2. Count the spaces between marks, not the marks themselves. Ask the child to demonstrate this on a familiar axis before reading a more demanding graph.
If there are four intervals instead, each represents 2.5. Do not assume a minor mark always stands for one unit. A different graph can use a different scale, even when the printed grid looks similar.

SECTION 3 OF 5
Check the starting value and any break
Inspect the first labelled value and any indicated axis break. A displayed axis need not begin at zero. For a uniform axis beginning at 50, moving two intervals of 5 gives 60, rather than 10.
For a graph with a specialised scale or other unfamiliar feature, ask the teacher or tutor to explain it. Use examples within the child’s taught scope. The first goal is to read the representation correctly, not introduce extra graph types.

SECTION 4 OF 5
Separate reading from interpretation
After finding a value, ask what the question requires: reporting it, comparing two values, calculating a difference or describing a pattern. Reading the graph correctly is one step. The subsequent reasoning must match the task.
If one point is 16 and another is 10 in the same unit, their difference is 6 in that unit. Preserve the quantities and units in the explanation. A correct subtraction cannot fix a value misread at the start.

SECTION 5 OF 5
Bring one fresh graph to the review
Keep the original misreading and the corrected interval explanation. Ask the tutor to choose another graph with a suitable different scale. Note whether the child checks the interval independently or waits for a reminder.
The Mathematics teaching guide describes inspecting workings in 3-pax tutorials. Apply that close attention to where the graph value first entered the solution. Confirm the relevant Maths or Science programme and school scope before choosing further practice.
